A pandemia da COVID-19 causou uma completa modificação nas formas de interação e comportamento social, visto que a contenção do vírus tornou-se prioridade mundial. O Estado, junto à medicina, passou a determinar os protocolos sanitários seguidos pela comunidade. A partir da indagação do filósofo Giorgio Agamben acerca da facilidade na qual uma sociedade permitiu considerar-se contagiada e entendendo como um período de calamidade deflagra a fragilidade da racionalidade científica diante da demanda por cura, neste artigo objetivou-se analisar se a medicina (...) tem respondido às demandas místicas a ela solicitadas, ou mesmo, se tem forjado demandas mistificadoras que reforçam seu lugar de poder social. Para tal, notas e documentos e posicionamentos de figuras políticas e instituições médicas brasileiras estarão aqui postos em pauta como vitrine que permite a análise da presença do caráter místico no discurso da medicina. É trazida aqui a oportunidade de ponderar as consequências decorrentes da ausência de questionamento acerca da cientificidade das instituições médicas e de suas influências na sociedade contemporânea. A exploração abrange não apenas o funcionamento baseado em conhecimento, mas também ressalta a influência da fé. Portanto, é um convite à reflexão sobre como a prática médica nos convida ao apego da crença na ciência. (shrink)

Female sex steroids can affect the motor system, modulating motor cortex excitability as well as performance in dexterity and coordination tasks. However, it has not yet been explored whether FSS affects the cognitive components of motor behavior. Mu is a sensorimotor rhythm observed by electroencephalography in alpha and beta frequency bands in practices such as motor imagery and action observation. This rhythm represents a window for studying the activity of neural circuits involved in motor cognition. Herein we investigated whether the (...) alpha-mu and beta-mu power in the sensorimotor region and the alpha and beta power over frontal, parietal, and occipital regions are modulated differently in the menstrual, follicular, and luteal phases of menstrual cycles in right-handed dominant women. To do so, these women underwent MI and AO in the three menstrual cycle phases. The spectral activity of the cortical regions for the alpha and beta bands were compared between phases of the menstrual cycle and a correlation analysis was also performed in relation to estrogen and progesterone levels. For the hypothesis-based approach, beta-mu event-related desynchronization was significantly stronger in the C3 channel in the follicular phase than in the menstrual and luteal phases. For the data-driven approach, beta ERD during MI was higher in the follicular phase than in the menstrual and luteal phases in the frontal region. These findings suggest the effect of FSS on executive movement control. No effect of menstrual cycle phases was observed in cortical areas investigated during OA, but alpha and beta bands correlated positively with the follicular phase plasma estradiol level. Thus, the attenuation of alpha and beta bands referring to mirror neuron activities appears to be associated with inhibition of cortical activity when estradiol levels are lower, improving cognitive processing of motor action.

The scientific community has debated the importance of “return” activities after ethnobiological studies. This issue has provoked debate because it touches on the ethics of research and the relationships with the people involved in these studies. This case study aimed to investigate community perception of an ethnobotany research project that was carried out in the semi-arid region of northeastern Brazil. Furthermore, we reported how the residents of this rural community felt about participating in the activities of “return” that arose from (...) the projects. Our findings demonstrate that “return” activities should be planned from the design phase of the research until its closure as a lifelong process that allows the communities involved to gradually take ownership of the information and actions that are being generated. Similarly, we argue that such activities must be negotiated with the people of the community so that they have decision-making power and autonomy to decide what is most relevant to their lives.

Due to the pandemic and the suspension of in-person school classes, there was an interruption in the meals served to approximately 40 million students who benefited from the Brazilian National School Feeding Program (PNAE). This article describes two case studies, comparing the strategies adopted by two municipalities for maintaining school feeding during the Covid-19 pandemic in the northern region of the state of Rio de Janeiro, Brazil, and discuss possible impacts of these strategies on food and nutrition security. These municipalities (...) together cover about 81% of the population in the region. In July 2020, we conducted interviews with PNAE municipal managers, following a qualitative approach. We discuss the results in relation to existing Brazilian guidance on food and nutrition security. The municipalities have developed distinct strategies to overcome operational obstacles and maintain PNAE goals, such as distributing food kits and making cash transfers to students’ families. The main determinants of these strategies are financial availability, the relationship between municipal teams and school communities, and the pre-pandemic PNAE logistics and management. Depending on the strategy and duration of the pandemic, the impacts on food and nutrition security can be wide-ranging, affecting food quality and local farmers who sell products to PNAE. It is necessary to acknowledge that this is not a short-term pandemic and find ways to perform school feeding in accordance with PNAE criteria. (shrink)

O presente trabalho tem como objetivo analisar o fenômeno do Totalitarismo no pensamento da filósofa alemã Hannah Arendt tendo como fio condutor a obra Origem do Totalitarismo. Verificaremos como a filósofa compreende o movimento totalitário e atuação do mesmo para capturar os seres humanos e destituí-los de todos os direitos usando para este fim os mais baixos artifícios, tais como os campos de concentração e o sistema propagandista ficcional. Focalizaremos especificamente no terceiro capítulo da obra supracitada, no qual a pensadora (...) apresenta os horrores das ditaduras e do Totalitarismo, revelando a face tenebrosa e cruel do homem.

As fraturas da sociedade salarial e o aumento da precariedade de vida levam diferentes setores a se engajarem em ações sociais. O artigo analisa o papel das corporações no enfrentamento dos problemas sociais a partir de um debate sobre o tipo de racionalidade subjacente ao modelo de desenvolvimento globalizado (pautado na razão indolente de Boaventura de Sousa Santos) e da análise da imbricação da economia na estrutura social (através da sociologia econômica). Os resultados demonstram que, apesar de alguns avanços (...) historicamente consolidados, práticas consideradas inovadoras por parte das corporações encontram substantivos desafios para ultrapassarem o nível da compensação, o que se relaciona com a permanência dos princípios da racionalidade mercantil. O estudo conclui que a genuína inovação social necessita considerar uma perspectiva de desenvolvimento e inovação baseada nas liberdades substantivas dos seres humanos. (shrink)

Taking literally the concept of emotional truth requires breaking the monopoly on truth of belief-like states. To this end, I look to perceptions for a model of non-propositional states that might be true or false, and to desires for a model of propositional attitudes the norm of which is other than the semantic satisfaction of their propositional object. Those models inspire a conception of generic truth, which can admit of degrees for analogue representations such as emotions; belief-like states, by contrast, (...) are digital representations. I argue that the gravest problem-objectivity-is not insurmountable. /// [Adam Morton] It is accuracy rather than truth itself that is valuable. Emotional truth is a dubious though attractive notion, but emotional accuracy is much easier to make sense of. My approach to accuracy goes via an account of what makes a story accurate. Stories can be accurate but not true, and emotions can be accurate whether or not they are true. The capacity for emotional accuracy, for emotions that fit a person's situation, is an aspect of emotional intelligence, which is as important an aspect of rational human agency as the intelligent formation of beliefs and desires.

In this urbane and witty book, Ronald de Sousa disputes the widespread notion that reason and emotion are natural antagonists.

How should we understand the emotional rationality? This first part will explore two models of cognition and analogy strategies, test their intuition about the emotional desire. I distinguish between subjective and objective desire, then presents with a feeling from the "paradigm of drama" export semantics, here our emotional repertoire is acquired all the learned, and our emotions in the form of an object is fixed. It is pretty well in line with the general principles of rationality, especially the lowest reasonable (...) principles. Turned to the second part of this side of reasonable. I will inquire how emotional beliefs, desires, and behaviors contribute to the rationality. I will present a very general biological hypothesis: emotions by controlling highlights the characteristics of perception and reasoning, so that we remove the difficulties due in particular to lead to paralysis; they are being simulated by a simplified perception of information, thus limiting our practice and cognitive choice. How are we to understand emotional or axiological rationality? I pursue analogies with both the cognitive and the strategic models, testing them against intuitions about emotional desires. We distinguish two different classes of desires, the subjective and the objective, and propose that emotions have a semantics that derives from "paradigmatic scenarios", in terms of which our emotional repertoire is learned and the formal objects of our emotions fixed. This fits in well with emerging facts about how our emotional capacities develop, and it can also be squared with the general principles of rationality, particularly minimal rationality. In the second part, I return to the perspective of rationality. I ask how emotions contribute to the rationality of beliefs, desires, and behavior. I proffer a very general biological hypothesis: Emotions spare us the paralysis potentially induced by a particular predicament by controlling the salience of features of perception and reasoning; they temporarily mimic the informational encapsulation of perception and so circumscribe our practical and cognitive options.

Do we love someone for their virtue, their beauty, or their moral or other qualities? Are love's characteristic desires altruistic or selfish? Are there duties of love? What do the sciences tell us about love? In this Very Short Introduction, Ronald de Sousa explores the different kinds of love, from affections to romantic love.

The word "truth" retains, in common use, traces of origins that link it to trust, truth, and truce, connoting ideas of fidelity, loyalty, and authenticity. The word has become, in contemporary philosophy, encased in a web of technicalities, but we know that a true image is a faithful portrait; a true friend a loyal one. In a novel or a poem, too, we have a feel for what is emotionally true, though we are not concerned with the actuality of events (...) and characters depicted. To have emotions is to care about certain things: we can wonder whether those things are really worth caring about. We can wonder whether our passions reflect who we are, and whether they constitute fitting responses to the vicissitudes of life. So there are two aspects to emotional truth: how well an emotion reflects the threats and promises of the world, and how well it reflects our own individual nature. That is the starting point of this book, which looks first at the analogies and disanalogies between strict propositional truth and a looser, "generic" sense of truth. As applied to emotions, generic truth is closer to those original meanings: as in a portrait's fidelity or friend's loyalty. Taken in this sense, the notion of emotional truth opens up large vistas on areas of life essential to our existence as social beings, and to our concerns with beauty, morality, love, death, sex, knowledge, desire, coherence, and happiness. Each of those topics illustrates some facet of the dominant theme of the book: the crucial but often ambivalent role of our emotions in grounding and yet also sometimes undermining our values. Emotions act, in holistic perspective, as ultimate arbiters of values where different and independently justified standards of value compete. (shrink)

Femininity and whiteness dominate Western nursing, silencing ontologies and epistemologies that do not align with these dominant norms while perpetuating systemic racism and discrimination in nursing practice, education, research, nursing activism, and sociopolitical structures. We propose Black feminist thought as a praxis to decenter, deconstruct, and unseat these ideologies and systems of power. Drawing from the work of past and present Black feminist scholars, we examine the ontological and epistemological perspectives of Black feminist thought. These include (i) the uniqueness and (...) particular experiences of people, (ii) the acceptance of ontological and epistemological pluralism of truths and ways of knowing, and (iii) the mandate for equity in the health, social, political, and environmental structures of society. By focusing our attention on lived experiences and voices of those systematically excluded in nursing practice, education, research, and society, Black feminist thought offers an anticolonial, antiracist, and antidiscriminatory foundation for more effectively upholding nursing's disciplinary mandate for social justice and equity.

The aim is to examine the performative acts and gender constitution in the context of the Second British Invasion. Despite the pervasive character of patriarchy and the prevalence of sexual difference as an operative cultural distinction, gender was not passively scripted on the bodies of many British singers. The subversive performances did not exclude suffering and marginalization but simultaneously undermined compulsory coherence.

Chronic migraine is a difficult disease to diagnose, and its pathophysiology remains undefined. Its symptoms affect the quality of life and daily living tasks of the affected person, leading to momentary disability. This is a pilot, randomized, controlled, double-blind clinical trial study with female patients between 18 and 65 years old with chronic migraine. The patients underwent twelve mindfulness sessions paired with anodal transcranial direct-current stimulation over the left dorsolateral prefrontal cortex, with current intensity of 2 mA applied for 20 (...) min, three times a week for 4 weeks. In addition, 20 min of mindfulness home practices were performed by guided meditation audio files. A total of 30 participants were evaluated after the treatment, and these were subdivided into two groups—active tDCS and sham tDCS, both set to mindfulness practice. The FFMQ-BR, MIDAS, and HIT-6 questionnaires were used to evaluate the outcomes. After the treatment, the active mindfulness and tDCS group showed better results in all outcomes. The sham group also showed improvements, but with smaller effect sizes compared to the active group. The only significant difference in the intergroup analysis was the outcome evaluated by HIT-6 in the post treatment result. Our results provide the first therapeutic evidence of mindfulness practices associated with left DLPFC anodal tDCS with a consequent increase in the level of full attention and analgesic benefits in the clinical symptoms of patients with chronic migraine.

Emotion Review, Volume 14, Issue 4, Page 257-261, October 2022. Müller argues that the perceptual or “Axiological Receptivity” model of emotions is incoherent, because it requires an emotion to apprehend and respond to its formal object at the same time. He defends a contrasting view of emotions as “Position-Takings" towards “formal objects”, aspects of an emotion's target pertinent to the subject's concerns. I first cast doubt on the cogency of Müller's attack on AR as begging questions about the temporal characteristics (...) of perceptual events. I then argue that Müller's version of PT is not radical enough. On my attitudinal view, formal objects are not values but natural properties that justify specific affective or behavioral responses. Values are constituted only by a negotiated social aggregation of individual evaluative attitudes. (shrink)

This study aims to examine the ethical decision-making model proposed by Schwartz, where we consider the factors of non-rationality and aspects that affect ethical judgments of auditors to make the decision to blow the whistle. In this paper, we argue that the intention of whistleblowing depends on ethical awareness and ethical judgment as well as there is a mediation–moderation due to emotion and perceived moral intensity of auditors. Data were collected using an online survey with 162 external auditors who worked (...) on audit firms in Indonesia as well as 173 internal auditors working in the manufacturing and financial services. The result of multigroup analysis shows that emotion can mediate the relationship between EAW and EJW. The nature of this relationship is more complex and then tested by adding moderating variables using consistent partial least squares approach. We found that EMT and PMI can improve the relationship between ethical judgments and whistleblowing intentions. These findings indicate that internal auditors are more likely to blow the whistle than external auditors; and reporting wrongdoing internally and anonymously are the preferred way of professional accountants to blow the whistle in Indonesia.

Emotions are Janus‐faced. They tell us something about the world, and they tell us something about ourselves. This suggests that we might speak of a truth, or perhaps two kinds of truths of emotions, one of which is about self and the other about conditions in the world. On some views, the latter comes by means of the former. Insofar as emotions manifest our inner life, however, we are more inclined to speak of authenticity rather than truth. What is the (...) difference? We need to distinguish the criteria of correspondence or appropriateness suitable for authenticity from those that embody the criterion of truth. Furthermore there is also a question about the transitions – among states of mind, and between states of mind and behaviour – that emotions encourage. This realm of transitions concerns rationality. After sketching the relevant distinctions, I will endeavour to justify the view that emotions should be appraised in terms of all three terms. (shrink)

Emotions can be the subject of moral judgments; they can also constitute the basis for moral judgments. The apparent circularity which arises if we accept both of these claims is the central topic of this paper: how can emotions be both judge and party in the moral court? The answer I offer regards all emotions as potentially relevant to ethics, rather than singling out a privileged set of moral emotions. It relies on taking a moderate position both on the question (...) of the naturalness of emotions and on that of their objectivity as revealers of value: emotions are neither simply natural nor socially constructed, and they apprehend objective values, but those values are multidimensional and relative to human realities. The axiological position I defend jettisons the usual foundations for ethical judgments, and grounds these judgments instead on a rationally informed reflective equilibrium of comprehensive emotional attitudes, tempered with a dose of irony.

Este artigo tem por objetivo apresentar o desenvolvimento do conceito de “vontade” na obra O mundo como vontade e representação (1818-9) do filósofo alemão Arthur Schopenhauer. Pretende-se apresentar o conceito perpassando inicialmente pela dicotomia kantiana da Crítica da razão pura entre “coisa em si” e “fenômeno”. Depois, seguiremos as observações feitas por Schopenhauer a essa categorização da realidade e suas ressalvas, para, então, explicitarmos a sua respectiva filosofia fundamentada na oposição entre “vontade” e “representação”. Por último, a influência desse pensamento (...) na denominada “segunda tópica” (pós 1920) na obra do pai da Psicanálise, Sigmund Freud. (shrink)

The movement of Artificial Intelligence (AI) research from universities to big corporations has had a significant impact on the development of the field. In the past, AI research was primarily conducted in academic institutions, which foster a culture of peer reviewing and collaboration to enhance quality improvements. The growing interest in AI among corporations, especially regarding Machine Learning (ML) technology, has shifted the focus of research from quality to quantity. Corporations have the resources to invest in large-scale ML projects and (...) they are often more interested in fast results than in ensuring that AI algorithms are reliable and safe. This paper proposes that the description of a Darwinian process made by the mathematician and physicist Freeman Dyson can be used to understand the implications of ML research scenario. The context of the Darwinian process—or lack thereof—can be used to draw a parallel between historical and current implications of technology expansion strongly driven by economic interests, making clear the consequences of shifting AI research from academia to industry. Finally, this paper indicates future directions for AI research to create a healthier environment for the evolution of ML technology. (shrink)

À quoi bon la pensée? Pour de nombreux chercheurs, inspirés par les théories évolutionnistes, la pensée réfléchie est utile à notre espèce. Elle lui confère des avantages importants et contribue à son succès reproductif. Pourtant ses avantages ne sont pas si évidents. La pensée ne figure ni dans les mécanismes de l'évolution qui ont façonné la vie, ni parmi les procédés dont se servent la plupart des organismes pour s'y maintenir. Dans Évolution et rationalité, Ronald de Sousa montre que, (...) pour comprendre les avantages de la pensée réfléchie, il faut changer nos présupposés relatifs à la rationalité et reconnaître la multiplicité de ses dimensions. La rationalité ne nous sert pas seulement à avoir des croyances vraies et à agir de manière efficace dans un environnement changeant. Elle nous aide à gérer nos plaisirs et nos peines dans le temps et nous permet d'envisager des situations qui n'existent pas. En général, le statut de la rationalité comme ensemble de capacités ayant évolué dans le cours de l'histoire naturelle de notre espèce, passant des tropismes aux désirs et de la détection à la représentation, n'a pas été pris suffisamment au sérieux. Suivre ce processus d'évolution de la rationalité permet de comprendre comment elle est devenue une norme, mais aussi pourquoi il lui arrive aussi souvent d'échouer. Ronald de Sousa a profondément modifié nos façons de concevoir les émotions. Avec Évolution et rationalité, il pourrait avoir une influence aussi décisive sur nos façons de concevoir la rationalité.

Even though the university has the potential to help humanity in what amounts to a paradigmatic transition, it has been very restrictive and very selective in the kinds of knowledges it validates. In fact, the kinds of knowledges in which it has excelled are those most responsible for the paradigmatic crisis in which humanity finds itself. In a nutshell, the paradigmatic change calls for cognitive justice, justice for the different ways of knowing that circulate in society. Cognitive justice is the (...) polar opposite of ‘anything goes’. The assumption is that there is no global social justice without global cognitive justice, justice among knowledges. Looking back, while privileging one specific kind of knowledge and, indeed, granting it a cognitive monopoly, the university has been the privileged site for producing and legitimating cognitive injustice. As a result, the immense epistemic diversity of the world has been ignored or suppressed. In the following, I identify the problem and the promise for overcoming it. (shrink)

The Philosophical search for Natural Kinds is motivated by the hope of finding ontological categories that are independent of our interests. Other requirements, of varying importance, are commonly made of kinds that claim to be natural. But no such categories are to be found. Virtually any kind can be termed ‘natural’ relative to some set of interests and epistemic priorities. Science determines those priorities at any particular stage of its progress, and what kinds are most ‘natural’ in that sense is (...) always a real and lively scientific question. The general philosophical problem of scientific realism is also real; but between the scientific and the metaphysical, the ‘Problem of Natural Kinds’ sits otiose. (shrink)

In this paper, I argue that, despite the progress made in recent years, virtue argumentation theory still lacks a more systematic acknowledgment of other-regarding virtues. A fuller recognition of such virtues not only enriches the field of research of virtue argumentation theory in significant ways, but also allows for a richer and more intuitive view of the virtuous arguer. A fully virtuous arguer, it is argued, should care to develop both self-regarding and other-regarding virtues. He should be concerned both with (...) his own development as an arguer and with helping other arguers in that regard. (shrink)

There are those who believe that modern society's reliance upon law, politics and science to both regulate and emancipate society has reached a crisis point and can no longer provide answers to current social problems. Toward a New Legal Common Sense engages in a series of sociological analyses of law in order to illustrate the need for a profound theoretical reconstruction of the notion of legality based on locality, nationality and globality. In this way the author shows how developments including (...) suprastate organisations such as the European Union and international human rights law can be given their proper place in the sociology of law, and suggests a new set of social structures that might sustain the emancipatory elements that have disappeared from modern society. This 2002 edition, of a title originally published by Routledge, is part of the acclaimed Law in Context Series, whose aim is to develop broad interdisciplinary perspectives on law. Toward a New Legal Common Sense is written for students taking law and globalisation courses, and political science, philosophy and sociology students doing optional subjects. (shrink)

Neste artigo, pretendo oferecer algumas razões para se dizer que Aristóteles sustenta a tese de que a εὐδαιμονία não apenas oferece o critério normativo que orienta a instituição e a reforma de regimes que estão aquém do melhor regime, como também é aquilo que é visado pela instituição e pela reforma destes regimes, pois o melhor regime não é, para Aristóteles, senão o regime no qual a εὐδαιμονία pode ser alcançada em máximo grau (cf. Pol. VII.13 1332a4-7).

In this article I argue that, in spite of the apparently unshakable hegemony of the historical, philosophical and sociological arguments invoked by the canonical history of Europe and the world to demonstrate the uniqueness of the West and its superiority, there is room to think of a non-Occidentalist West. By that I mean a vast array of conceptions, theories, arguments that, though produced in the West by recognized intellectual figures, were discarded, marginalized or ignored because they did not fit the (...) political objectives of capitalism and colonialism at the roots of Western modernity. In the article I tackle specifically three topics: the conceptions of antiquity, modern science and a teleology of the future. Among many others who might be selected, I resort to three eccentric figures — Lucian of Samosata, Nicholas of Cusa and Blaise Pascal — to exemplify some of the paths that might guide us in the construction of a non-capitalist, non-colonialist inter-cultural dialogue. Such paths are here designated as those of learned ignorance, ecology of knowledge, wager on another possible world and artisanship of practices. (shrink)

The question What is an individual? goes back beyond Aristotle’s discussion of substance to the Ionians’ preoccupation with the paradox of change -- the fact that if anything changes it must stay the same. Mere reflection on this fact and the common-sense notion of a countable thing yields a concept of a “minimal individual”, which is particular (a logical matter) specific (a taxonomic matter), and unique (an evaluative empirical matter). Individuals occupy space, and therefore might be dislodged. Even minimal individuals, (...) therefore (Strawsonian individual or Aristotelian substance) already contain the potential for competition or conflict. What is added by biology to this basic notion? It emerges from some recent work on the evolution of metazoan animals that individuals as we know them are minimal individuals towhich four features have been added, and which appear to be inseparable: differentiated multicellularity; sexual reproduction; segregation of germ from somatic cells; and obligatory death. Whether or not individuals are to be counted as units of selection, they are not the beneficiaries of natural selection. (shrink)

In this essay, I will focus on the two main objections that have been adduced against the moral acceptability of contempt: the fact that it embraces a whole person and not merely some deed or aspect of a person’s character, and the way that when addressed to a person in this way, it amounts to a denial of the very personhood of its target.

Contemporary philosophers have paid increasing attention to the empirical research on emotions that has blossomed in many areas of the social sciences. In this paper, I first sketch the common roots of science and philosophy in Ancient Greek thought. I illustrate the way that specific empirical sciences can be regarded as branching out from a central trunk of philosophical speculation. On the basis of seven informal characterizations of what is distinctive about philosophical thinking, I then draw attention to the fact (...) that scientific progress frequently requires one to make adjustments to the way its basic terms are conceptualized, and thus cannot avoid philosophical thought. The character of emotions requires attention from many disciplines, and the links among those disciplines inevitably require a broader philosophical perspective to be understood. Thus, emotion science, and indeed all of science, is inextricably committed to philosophical assumptions that demand scrutiny. (shrink)

The study of consciousness is poised today at interesting crossroads. There has been a surge of research into various neurobiological underpinnings of consciousness in the past decade. The present article looks at the theories regarding this complex phenomenon, especially the ones that neurobiology, cognitive neuroscience and cognitive psychology have to offer. We will first discuss the origin and etymology of word consciousness and its usage. Neurobiological correlates of consciousness are discussed with structures like the ascending reticular activating system, the amygdala, (...) the cerebellum, the thalamus, the frontoparietal circuits, the prefrontal cortex and the precuneus. The cellular and microlevel theories of consciousness and cerebral activity at the neuronal level contributing to consciousness are highlighted, along with the various theories posited in this area. The role of neuronal assemblies and circuits along with firing patterns and their ramifications for the understanding of consciousness are discussed. A section on the role of anaesthesia and its links to consciousness is presented, along with details of split-brain studies in consciousness and altered states of awareness, including the vegetative states. The article finally discusses the progress cognitive psychology has made in identifying and theorising various perspectives of consciousness, perceptual awareness and conscious processing. Both recent and past researches are highlighted. The importance and salient features of each theory are discussed along with the pitfalls, if present. A need for integration of various theories to understand consciousness from a holistic perspective is stressed, to enable one to reach a theory that explains the ultimate neurobiology of consciousness.
