Clark & Thornton are too hasty in their dismissal of uninformed learning; nonmonotonic processing units show considerable promise on type-2 tasks. I describe a simulation which succeeds on a “pure” type-2 problem. Another simulation challenges Clark & Thornton 's claims about the serendipitous nature of solutions to type-2 problems.

In his target article Page proposes a definition of the term “localist.” In this commentary I argue that his definition does not serve to make a principled distinction, as the inclusion of vague terms make it susceptible to some problematic counterexamples.

Benevolent intersubjectivity developed in parent–infant interactions and compassion toward friend and foe alike are non-violent interventions to group behavior in conflict. Based on a dyadic active inference framework rooted in specific parental brain mechanisms, we suggest that interventions promoting compassion and intersubjectivity can reduce stress, and that compassionate mediation may resolve conflicts.

The dance metaphor of ape-human communication is valuable and needs to be pressed to its logical conclusion. When couples dance, they are both choreographers and dancers, and the dance arises dialectically out of the “peractions” of the dancers. We suppose that the way in which scientists communicate with their apes emerges by an analogous process.

Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The (...) animal was stereotactically irradiated at the level of the visual cortex upon defining the target by a fused cerebral MRI and CT scan. A fully implantable neural telemetry system consisting of a 64 channel intracortical multielectrode array, a telemetry capsule, and an inductive rechargeable battery was then implanted into the visual cortex to record and manipulate local field potentials, and multi-unit activity. We achieved a 3-month stability of the functionality of the un-tethered BCI in terms of telemetric radio-communication, inductive battery charging, and device biocompatibility for 3 months. Finally, we could reliably record the local signature of sub- and suprathreshold neuronal activity in the visual cortex with high bandwidth without complications. The ability to wireless induction charging combined with the entirely implantable design, the rather high recording bandwidth, and the ability to record and stimulate simultaneously put forward a wireless BCI capable of long-term un-tethered real-time communication for causal preclinical circuit-based closed-loop interventions.

We explore Madole & Harden's (2022) suggestion that single-nucleotide polymorphism (SNP)/trait correlations are analogous to randomized experiments and thus can be given a causal interpretation.

The brain and body need to adapt constantly to changing social and physical environments. A key mechanism for this adaptation is the ‘stress response’, which is necessary and not negative in and of itself. The term ‘stress’, however, is ambiguous and has acquired negative connotations. We argue that the concept of allostasis can be used instead to describe the mechanisms employed to achieve stability of homeostatic systems through active intervention (adaptive plasticity). In the context of allostasis, resilience denotes the ability (...) of an organism to respond to stressors in the environment by means of the appropriate engagement and efficient termination of allostatic responses. In this review, we discuss the neurobiological and organismal factors that modulate resilience, such as growth factors, chaperone molecules and circadian rhythms, and highlight its consequences for cognition and behavior.

© 2016 Elsevier LtdJumping spiders are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level. Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds by freezing—a common (...) anti-predatory behavior characteristic of an acoustic startle response. Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones —recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. Thus, these spiders appear able to detect airborne sound at distances in the acoustic far-field region, beyond the near-field range often thought to bound acoustic perception in arthropods that lack tympanic ears [2]. Furthermore, direct mechanical stimulation of hairs on the patella of the foreleg was sufficient to generate responses in neural units that also responded to airborne acoustic stimuli—evidence that these hairs likely play a role in the detection of acoustic cues. We suggest that these auditory responses enable the detection of predators and facilitate an acoustic startle response. Video. (shrink)

This compilation brings together 20 essays of Santiago Ramón y Cajal (1852-1934), the neuroscientist par excellence and 1906 Nobel Laureate in Medicine, on topics beyond neuroanatomy, most appearing in English for the first time. The annotated collection makes available in one handy volume Cajal's ideas on psychology, art and education, still current and still relevant, derived from his books La Psicología de los Artistas, Charlas de Café, El Mundo Visto a los Ochenta Años, Pensamientos Pedagógicos and Escritos Inéditos. An acute (...) observer of the intellectual and social scene of the avant-garde, Cajal emerged in 20th-century Spain in a further role as a philosopher and educator. The contents bespeak Cajal's inquiry into the varieties of human experience and shed new light on the breadth of his genius, imagination and passion, helping us to rethink what we thought we already understood about Don Santiago's own mind.

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

Open peer commentary on the target article “Who Conceives of Society?” by Ernst von Glasersfeld. Excerpt: In the face of modern neuroscience we should give up on constructivism, even more so on radical constructivism, and stick to the physical and psychological reality given in science and daily life, even if it is the brain’s illusion from associative networks. The illusion of constructivism may hurt!

Cook et al. overstate the evidence supporting their associative account of mirror neurons in humans: most studies do not address a key property, action-specificity that generalizes across the visual and motor domains. Multivariate pattern analysis of neuroimaging data can address this concern, and we illustrate how MVPA can be used to test key predictions of their account.

By synthesizing evolutionary, attachment, and acoustic perspectives, Soltis has provided an innovative model of infant cry acoustics and parental responsiveness. We question some of his hypotheses, however, because of the limited extant data on infant crying among hunter-gatherers. We also question Soltis' distinction between manipulative and honest signaling based upon recent contributions from attachment theory.

In recent years, direct brain interventions have shown increased success in manipulating neurobiological processes often associated with moral reasoning and decision-making. As current DBIs are refined, and new technologies are developed, the state will have an interest in administering DBIs to criminal offenders for rehabilitative purposes. However, it is generally assumed that the state is not justified in directly intruding in an offender’s brain without valid consent. Thomas Douglas challenges this view. The state already forces criminal offenders to go to (...) jail without their consent. This represents a serious interference with an offender’s rights. If criminal offenders are already morally liable to incarceration, why is the state not also entitled to administer DBIs without consent for the purposes of rehabilitation? Douglas argument focuses on the right to ‘bodily integrity’. He argues that there is no compelling reason to believe that bodily rights that protect an offender from non-consensual DBIs are stronger than rights that protect an offender from incarceration. This paper will extend Douglas’ analysis. It will consider the more fundamental right to ‘mental integrity’. The right to mental integrity defends an inner sphere of liberty. It protects critical capacities necessary for the exercise of autonomous human agency—without which a vast majority of moral rights could not exist. Thus, the right to mental integrity is ultimately more important for a moral assessment of DBIs. The right strongly suggests that both presently, and in the future, there may be many cases in which the state is not entitled to administer DBIs to criminal offenders without valid consent.

The psychological state and neural correlates of 19 women undergoing normal childbirth were studied. Frequent occurence of nonordinary psychological phenomena was traced back in 6 subjects, occurring in active and passive alertness, as well as hypnagogic/hypnopompic periods, and in dreaming, during the late period of pregnancy, giving birth, and the period of 2-4 days post partull. The brain activity of the aforementioned subgroup during this time was characterized primarily by general activation of the right hemisphere in the bandpass of infraslow (...) electrical processes and by more localized EEG activation. The implications of the data for research on gender-specific altered states of consciousness are discussed. (shrink)

The possible role of the neurotransmitter serotonin in human affiliative behavior is under-examined in the review by Depue & Morrone-Strupinsky (D&M-S). This commentary reviews evidence indicating that serotonin not only inhibits aggressive behavior that may be detrimental to affiliative bonds with others in a social group but serotonin also enhances prosocial behaviors that may facilitate ties to the social group.

This article introduces the special issue on the brain and processing of nonliteral and other forms of language in which meaning is "stretched" or deviates from expectations. The introduction consists of 2 sections meant to orient the reader to the articles that follow. The first section is a brief review and commentary on recent research and theorizing into the evolution of the human brain, selected brain structures, and implications that arise for nonliteral language and thought. The second section reviews and (...) comments on recent advances in technology in cognitive neuroscience that increasingly are being brought to bear on questions of how we process a range of language forms that deviate from literal usage. I take the evidence as indicating that normal understanding of nonliteral language is highly interactive, involving multiple parts of the brain and, based on temporal processing in the brain, these interactions occur very early in the processing of a trope.

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

A major problem in developing an effective gene therapy for the nervous system lies in understanding the principles that maintain or turn off the expression of genes following their transfer into the CNS.

The sensation of red light falling on your eyes has something in common with the experience of looking at a cartoon in the New Yorker. The phenomenal quality of the sensation and the funniness of the joke are both properties of your subjective take on an external event and both arise in two steps. With sensations, your brain responds to signals from bodily sense organs with an internalized evaluative response; your mind reads this response and represents what it's like as (...) the subjective property of redness. With jokes, the cartoonist creates a clever drawing; your mind takes in the drawing and represents what it's like as the subjective property of funniness. This analogy -- deliberately deflationary -- helps elucidate the nature of phenomenal consciousness and its neural correlates, and exposes the 'hard problem' as a conceptual error. (shrink)

The target article by Bernard Baars presents a quick way of grasping the gist of his book In the Theater of Consciousness: The Workspace of the Mind, published recently . The metaphor of consciousness as a theatre has a long history. A prototype of the theatre model may be traced back to Plato's Allegory of the Cave, in which we are like prisoners living in a cave just observing the shadows of reality. The modern theatre model insists on consciousness being (...) under the control of attention by introducing a searchlight metaphor . The target article explores some evidence from the viewpoint of Global Workspace theory by using a method of ‘contrastive analysis’. According to this theory, GW works as the publicity organ of the brain and has a facility for accessing, disseminating, and exchanging information, and for exercizing global coordination and control . Baars describes his GW as a theatre. ‘As the house lights begin to dim and the audience falls silent, a single spotlight pierces the descending darkness, until only one bright spot, shining on stage, remains visible. You know that the audience, actors, stagehands, and spotlight operators are there, working together under invisible direction and guided by an unknown script, to present the flow of visible events on stage. As the house lights dim, only the focal contents of consciousness remain. Everything else is in darkness’ . According to GW theory, a theatre stage with a bright spot is just a working memory. So I would like to comment on some general characteristics of the working memory and related spotlight problem. (shrink)

“Dance” has been associated with many psychophysiological and medical health effects. However, varying definitions of what constitute “dance” have led to a rather heterogenous body of evidence about such potential effects, leaving the picture piecemeal at best. It remains unclear what exact parameters may be driving positive effects. We believe that this heterogeneity of evidence is partly due to a lack of a clear definition of dance for such empirical purposes. A differentiation is needed between (a) the effects on the (...) individual when the activity of “dancing” is enjoyedas a dancerwithindifferent dance domains(e.g.,professional/”high-art”type of dance,eroticdance,religiousdance,clubdancing,Dance Movement Therapy(DMT), and what is commonly known ashobby, recreationalorsocialdance), and (b) the effects on the individual within these different domains, as a dancer of thedifferent dance styles(solo dance, partnering dance, group dance; and all the different styles within these). Another separate category of dance engagement is, not as a dancer, but as a spectator of all of the above. “Watching dance” as part of an audience has its own set of psychophysiological and neurocognitive effects on the individual, and depends on the context where dance is witnessed. With the help of dance professionals, we first outline some different dance domains and dance styles, and outline aspects that differentiate them, and that may, therefore, cause differential empirical findings when compared regardless (e.g., amount of interpersonal contact, physical exertion, context, cognitive demand, type of movements, complexity of technique and ratio of choreography/improvisation). Then, we outline commonalities between all dance styles. We identify six basic components that are part of any dance practice, as part of a continuum, and review and discuss available research for each of them concerning the possible health and wellbeing effects of each of these components, and how they may relate to the psychophysiological and health effects that are reported for “dancing”: (1) rhythm and music, (2) sociality, (3) technique and fitness, (4) connection and connectedness (self-intimation), (5) flow and mindfulness, (6) aesthetic emotions and imagination. Future research efforts might take into account the important differences between types of dance activities, as well as the six components, for a more targeted assessment of how “dancing” affects the human body.

Background Deep brain stimulation is approved for treating refractory obsessive-compulsive disorder in adults under the US Food and Drug Administration Humanitarian Device Exemption, and studies have shown its efficacy in reducing symptom severity and improving quality of life. While similar deep brain stimulation treatment is available for pediatric patients with dystonia, it is not yet available for pediatric patients with obsessive-compulsive disorder, although soon could be. The prospect of growing indications for pediatric deep brain stimulation raises several ethical concerns relating (...) to bodily integrity, the ability to offer informed assent, and the role pediatric patients play in the decision-making process. Objective The aim of this study is to solicit and assess the views of stakeholders (children, parents, clinicians) on pediatric assent, autonomy, and bodily integrity in the context of potential pediatric deep brain stimulation for obsessive-compulsive disorder. Methods Semi-structured interviews were conducted with pediatric obsessive-compulsive disorder patients ( n = 21), caregivers of pediatric obsessive-compulsive disorder patients aged 14–18 ( n = 19), and clinicians with experience treating refractory obsessive-compulsive disorder ( n = 25). Interviews were transcribed and coded in MAXQDA 2018 and 2020 software and processed for thematic content analysis to isolate and compare specific themes. Results A majority of respondents (74%, 48/65) across all three stakeholder groups voiced that the decision-making process should be collaborative and involve everyone (clinicians: 84% or 21/25, caregivers 71% or 15/21, and patients 63% or 12/19). We identified a split between respondents’ views on who should have the final say in the event of disagreement (38% or 25/65 favored the patient versus 35% or 23/65 favoring caregivers). A split between respondents also emerged concerning the maturity relevant for deep brain stimulation decision-making, with 45% (29/65) favoring developmental maturity (age/physiological development) and 45% (29/65) favoring decisional maturity (capacity to understand and weigh information). A majority of clinicians indicated that they would not move forward with deep brain stimulation without securing patient assent (80% or 20/25), with some stating the only exception is if patient quality of life was very poor and/or they lacked insight. Both caregivers and patients expressed a significant respect for the patient's right to bodily integrity, with 67% of caregivers (14/21) and 68% of patients (13/19) justifying patient involvement in decision-making specifically with reference to infringements of bodily integrity. Conclusion Our findings demonstrate that despite broad agreement across stakeholders that the decision-making process for pediatric deep brain stimulation for obsessive-compulsive disorder should be collaborative and somehow involve pediatric patients, there is disagreement about what this process entails and what factors determine patient involvement in the process. However, there is agreement that children have a right to bodily and brain integrity, which should only be infringed upon in rare circumstances. (shrink)

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

Rachlin's view of self-control is rejected on the grounds that his arguments do not establish the possibility of abstract, external, stimulus patterns and that his experiments, although they show that pigeons and human beings do sometimes choose postponed rather than immediate gratification, do not challenge the commonly held view that internal factors are involved in the former choice.

The tsunami effect of the COVID-19 pandemic is affecting many aspects of scientific activities. Multidisciplinary experimental studies with international collaborators are hindered by the closing of the national borders, logistic issues due to lockdown, quarantine restrictions, and social distancing requirements. The full impact of this crisis on science is not clear yet, but the above-mentioned issues have most certainly restrained academic research activities. Sharing innovative solutions between researchers is in high demand in this situation. The aim of this paper is (...) to share our successful practice of using web-based communication and remote control software for real-time long-distance control of brain stimulation. This solution may guide and encourage researchers to cope with restrictions and has the potential to help expanding international collaborations by lowering travel time and costs. (shrink)

Extensive research has demonstrated that rs1360780, a common single nucleotide polymorphism within the FKBP5 gene, interacts with early-life stress in predicting psychopathology. Previous results suggest that carriers of the TT genotype of rs1360780 who were exposed to child abuse show differences in structure and functional activation of emotion-processing brain areas belonging to the salience network. Extending these findings on intermediate phenotypes of psychopathology, we examined if the interaction between rs1360780 and child abuse predicts resting-state functional connectivity (rsFC) between the amygdala (...) and other areas of the salience network. We analyzed data of young European adults from the general population (N = 774; mean age = 18.76 years) who took part in the IMAGEN study. In the absence of main effects of genotype and abuse, a significant interaction effect was observed for rsFC between the right centromedial amygdala and right posterior insula (p <.025, FWE-corrected), which was driven by stronger rsFC in TT allele carriers with a history of abuse. Our results suggest that the TT genotype of rs1360780 may render individuals with a history of abuse more vulnerable to functional changes in communication between brain areas processing emotions and bodily sensations, which could underlie or increase the risk for psychopathology.
