    Detrended Fluctuation, Coherence, and Spectral Power Analysis of Activation Rearrangement in EEG Dynamics During Cognitive Workload.Ivan Seleznov, Igor Zyma, Ken Kiyono, Sergii Tukaev, Anton Popov, Mariia Chernykh & Oleksii Shpenkov - 2019 - Frontiers in Human Neuroscience 13:463672.
    In the study of human cognitive activity using electroencephalogram (EEG), the brain dynamics parameters and characteristics play a crucial role. They allow to investigate the changes in functionality depending on the environment and task performance process, and also to access the intensity of the brain activity in various locations of the cortex and its dependencies. Usually, the dynamics of activation of different brain areas during the cognitive tasks are being studied by spectral analysis based on power spectral density (...)

    Long-Term Inquiry Meditation Reduces EEG Spectral Dynamics in Self-Schema Processing.Junling Gao, Hang Kin Leung, Bonnie Wai Yan Wu, Jenny Hung, Chunqi Chang & Hin Hung Sik - 2023 - Heliyon 9 (9).
    Abstract Objective Intuitive inquiry meditation is a unique form of Buddhist Zen/Chan practice in which individuals actively and intuitively utilize the cognitive functions to cultivate doubt and explore the concept of the self. This event-related potential (ERP) study aimed to investigate the neural correlates by which long-term practice of intuitive inquiry meditation induces flexibility in self-schema processing, highlighting the role of doubt and belief processes in this exploration. Methods Twenty experienced and eighteen beginner meditators in intuitive inquiry meditation were recruited (...)

    Hypnotic induction is followed by state-like changes in the organization of EEG functional connectivity in the theta and beta frequency bands in high-hypnotically susceptible individuals.Graham A. Jamieson & Adrian P. Burgess - 2014 - Frontiers in Human Neuroscience 8:86859.
    Altered state theories of hypnosis posit that a qualitatively distinct state of mental processing, which emerges in those with high hypnotic susceptibility following a hypnotic induction, enables the generation of anomalous experiences in response to specific hypnotic suggestions. If so then such a state should be observable as a discrete pattern of changes to functional connectivity (shared information) between brain regions following a hypnotic induction in high but not low hypnotically susceptible participants. Twenty-eight channel EEG was recorded from 12 high (...)

  4. Noise from the Periphery in Autism.Maria Brincker & Elizabeth B. Torres - 2013 - Frontiers in Integrative Neuroscience 7:34.
    No two individuals with the autism diagnosis are ever the same—yet many practitioners and parents can recognize signs of ASD very rapidly with the naked eye. What, then, is this phenotype of autism that shows itself across such distinct clinical presentations and heterogeneous developments? The “signs” seem notoriously slippery and resistant to the behavioral threshold categories that make up current assessment tools. Part of the problem is that cognitive and behavioral “abilities” typically are theorized as high-level disembodied and modular functions—that (...)

    continent. 1.1 : 3-13. / 0/ – Introduction I want to propose, as a trajectory into the philosophically weird, an absurd theoretical claim and pursue it, or perhaps more accurately, construct it as I point to it, collecting the ground work behind me like the Perpetual Train from China Mieville's Iron Council which puts down track as it moves reclaiming it along the way. The strange trajectory is the following: Kant's critical philosophy and much of continental philosophy which has followed, (...)

    Dans cette contribution, j'examinerai l'argument qui renvoie dos à dos le théisme et l'athéisme et qui structure la présentation de l'alternative que constitue le Dieu à venir. N'étant ni adhérant, ni sympathisant du réalisme spéculatif, je ne proposerai pourtant pas de critique externe de la philosophie de la religion proposée par Meillassoux. De manière heuristique, je vais tenir pour acquis Après la finitude et je montrerai ce qui me semble être les faiblesses de l'argument, critiques rendant finalement peu crédible l'affirmation (...)

    Compatible statistical interpretation of a wave packet.Mirjana Božić & Zvonko Marić - 1995 - Foundations of Physics 25 (1):159-173.
    A compatible statistical interpretation of a wave packet is proposed. De Broglian probabilities which unite wave and particle features of quantons are evaluated for free wave packets and Jor a superposition of wave packets. The obtained expressions provide a very plausible and physically appealing explanation of coherence in apparently incoherent beams and of the characteristic modulation of the momentum distribution, found recently in neutron interferometry combined with spectral filtering. Certain conclusions about dualism and objectivity in quantum domain are (...)

    Functional organization and restoration of the brain motor-execution network after stroke and rehabilitation.Sahil Bajaj, Andrew J. Butler, Daniel Drake & Mukesh Dhamala - 2015 - Frontiers in Human Neuroscience 9:134070.
    Multiple cortical areas of the human brain motor system interact coherently in the low frequency range (< 0.1 Hz), even in the absence of explicit tasks. Following stroke, cortical interactions are functionally disturbed. How these interactions are affected and how the functional organization is regained from rehabilitative treatments as people begin to recover motor behaviors has not been systematically studied. We recorded the intrinsic functional magnetic resonance imaging (fMRI) signals from 30 participants: 17 young healthy controls and 13 aged stroke (...)

    Spectral Nationality: Passages of Freedom from Kant to Postcolonial Literatures of Liberation.Pheng Cheah - 2003 - Columbia University Press.
    This far-ranging and ambitious attempt to rethink postcolonial theory's discussion of the nation and nationalism brings the problems of the postcolonial condition to bear on the philosophy of freedom. Closely identified with totalitarianism and fundamentalism, the nation-state has a tainted history of coercion, ethnic violence, and even, as in ultranationalist Nazi Germany, genocide. Most contemporary theorists are therefore skeptical, if not altogether dismissive, of the idea of the nation and the related metaphor of the political body as an organism. Going (...)

    Undecidability of the Spectral Gap: An Epistemological Look.Emiliano Ippoliti & Sergio Caprara - 2021 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 52 (1):157-170.
    The results of Cubitt et al. on the spectral gap problem add a new chapter to the issue of undecidability in physics, as they show that it is impossible to decide whether the Hamiltonian of a quantum many-body system is gapped or gapless. This implies, amongst other things, that a reductionist viewpoint would be untenable. In this paper, we examine their proof and a few philosophical implications, in particular ones regarding models and limitative results. In more detail, we examine (...)

    The Spectricity of Humanness: Spectral Ontology and Being-in-the-World.Zachary Isrow - 2022 - Berlin, Germany: Walter De Gruyter.
    The question of humanness requires a philosophical anthropology and we need a revision of what philosophical anthropology means in light of contemporary efforts in speculative realism and object-oriented ontology. This is the main claim of the book which expands into the smaller supporting claims that 1) contemporary work in speculative realism indicates that Heidegger’s analytic of Dasein needs to be rethought in consideration of certain Kantian values 2) recent philosophical anthropology offers an incomplete look at the central concern of philosophical (...)

    Spectral bodies: Derrida and the philosophy of the photograph as historical document.Nick Peim - 2005 - Journal of Philosophy of Education 39 (1):67–84.
    Marx's call for a materialism capable of engaging reality as ‘sensuous human activity’ opens a question about the role of representation in relation to data. Images have increasingly been seen as significant forms of data in the history of education. Derrida's theory of the spectre—a variation on the positions established in his earlier works on the trace, the supplement and differance—offers a way of rethinking visual images, their relations with existing discourses of knowledge and with positioned subjects who makes sense.

    Coherence of Socio-Cultural Processes: On the Problem of Methodology.В. С Шмаков - 2022 - Siberian Journal of Philosophy 20 (2):103-111.
    The article deals with the problems of methodology for studying the dynamics of socio-cultural processes of local communities in the context of globalization. The purpose of the study is a methodological analysis of the problem of competition, from the point of view of global and local specifics of the development of culture and sociality. Modernization processes generate a paradigm of socio-cultural development that fixes the scale of action, methods and means of interrelation and existence of elements and subsys­tems that influence (...)

    Spectral Strangers: Charlotte Brontë’s teachers.Nesta Devine - 2013 - Educational Philosophy and Theory 45 (4):383-395.
    In this article I attempt to engage with Charlotte Brontë as both a teacher and a philosopher. In her depiction of two impoverished gentlewomen as teachers Brontë is, as is often pointed out, drawing on her own history, but she is also exploring two conflicting contemporary philosophic notions: the romantic ideal and the ideal of rationality, as they are played out in the lives of women. Brontë uses the plot device of taking her teachers into new environments, from where as (...)

    The Coherence Hypothesis: Critical Reconsideration, Reception History and Development of a Theoretical Model.Florian Jeserich - 2014 - Archive for the Psychology of Religion 36 (1):1-51.
    It is still largely unclear which pathways explain the religion-health connection and how these mechanisms work. One such intervening mechanism, coherence, is the focus of this article. Based on database searches and a review of the literature retrieved, I differentiate between six meanings of coherence in religion-related research: 1) consistency; 2) credibility; 3) congruence; 4) confidence; 5) character; and 6) cohesion. In this article, this classification is utilized to analyse the conceptualizations and operationalizations of coherence within a (...)

    When it became uncool to speak of beauty with respect to pieces of art, physicists started claiming that their results are beautiful. They say, for example, that a theory's beauty speaks in favour of its truth, and that they strive to perform beautiful experiments. What does that mean? The notion cannot be defined. (It cannot be defined in the arts either). Therefore, I elucidate it with examples of optical experimentation. Desaguliers' white synthesis, for example, is more beautiful than Newton's, and (...)

    While some may argue that universities are in a state of crisis, others claim that we are living in a post-university era; a time after universities. If there was a battle for the survival of the institution it is over and done with. The buildings still stand. Students enrol and may attend lectures, though most do not. But virtually nothing real remains. What some mistakenly take to be a university is, in actuality, an “uncanny” spectral presence. The encompassing ethico-philosophical (...)

  36. Spectral Statistics of the Rectangular Billiard with a Flux Line.Saar Rahav & Shmuel Fishman - 2001 - Foundations of Physics 31 (1):115-146.
    The density of states of a rectangular billiard with an Aharonov–Bohm flux line in its center was calculated in the semiclassical approximation and was used for the calculation of the form factor in the diagonal approximation. The distribution of nearest level spacings and the form factor were calculated also numerically. For some values of the flux these were found to be close to the ones of the semi-Poisson statistics. The difference between the numerical results and the semiclassical ones were found (...)

    The Spectral Dilemma and the Instauration of the Divine: Latour contra Meillassoux.Michael Norton - 2014 - ThéoRèmes 6 (1).
    Quentin Meillassoux has argued that lives irremediably ruined by injustice, suffering, and tragedy confront us with an irresolvable dilemma: either God exists to bring justice to the world, or God does not exist and true justice is an impossibility. He proposes to escape this dilemma by introducing the idea of a “virtual” God who does not exist now but who could unpredictably come into existence in the future. According to Meillassoux’s argument, such an event would entail a radical break with (...)

    The prospects for a phenomenology of technology have been guided in the past decade by a split between supporters of Martin Heidegger and those who subscribe to Bernard Stiegler’s critique of Heidegger. This essay proposes that both are needed for a phenomenology of what Edward Castronova calls “synthetic worlds” (large on-line environments like Second Life and World of Warcraft). Here is a phenomenology that must take into account histories of design and technical evolution to account for the particular “fantasy of (...)
