Apical amplification-a cellular mechanism of conscious perception?

Neuroscience of Consciousness 2021 Tomáš Marvan, Michal Polák, Talis Bachmann et al.

We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted...

Consciousness as a Product of Evolution: Contents, Selector Circuits, and Trajectories in Experience Space.

Frontiers in Systems Neuroscience 2021 Thurston Lacalli

Conscious experience can be treated as a complex unified whole, but to do so is problematic from an evolutionary perspective if, like other products of evolution, consciousness had simple beginnings, and achieved complexity only secondarily over an extended period of time as new categories of subjective experience were added and refined. The premise here is twofold, first that these simple...

Pharmacological assistance for psychotherapy

Emerging Trends in Drugs, Addictions, and Health 2021 Jessica Lochtenberg, Ari P. Kirshenbaum, Matthew W. Johnson 2 citations

Recent interest has emerged regarding the use of several short-acting pharmacotherapies that may be explicitly delivered in the context of psychotherapy for anxiety, mood and substance-dependence disorders. Our objective in this narrative review is to highlight the potential of medically-assisted psychotherapy by outlining the current state of research on some of these drugs, including...

Enacting Plant-Inspired Robotics.

Frontiers in Neurorobotics 2021 Jonny Lee, Paco Calvo

Plants offer a source of bioinspiration for soft robotics. Nevertheless, a gap remains in designing robots based on the fundamental principles of plant intelligence, rooted in a non-centralized, modular architecture and a highly plastic phenotype. We contend that a holistic approach to plant bioinspiration-one that draws more fully on the features of plant intelligence and behavior-evidences...

Dissociation in Patients with Non-Psychotic Mental Disorders

Psychology in Russia State of Art 2021 Rinata Iskanderova, Valeriy V. Vasilyev 1 citation

Background. Dissociation is a generally recognized phenomenon in psychology and psychiatry; however, questions are still not fully resolved about the di!erence between pathological and normal dissociation, as well as the role of dissociation, depending on its aetiology, in the formation of clinical manifestations of mental disorders. Objective. To complement the existing data about the...

Peripheral biomarkers in Repeated Ketamine Infusions Trial

2021 Amanda van Geel

Abnormalities in the endocrine and immune systems are well documented in patients with Major Depressive Disorder (MDD), however, the mechanisms by which the novel antidepressant treatment, ketamine, influences these physiological systems are unclear. This study examined the effects of repeated ketamine infusions on the endocrine and immune systems using the peripheral biomarkers C-reactive...

Toward an Embodied, Embedded Predictive Processing Account.

Frontiers in Psychology 2021 Elmarie Venter 35 citations

In this paper, I argue for an embodied, embedded approach to predictive processing and thus align the framework with situated cognition. The recent popularity of theories conceiving of the brain as a predictive organ has given rise to two broad camps in the literature that I call free energy enactivism and cognitivist predictive processing. The two approaches vary in scope and methodology. The...

A Relativistic Theory of Consciousness.

Frontiers in Psychology 2021 Nir Lahav, Zachariah A Neemeh 27 citations

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an "explanatory gap" between our scientific knowledge of functional consciousness and its...

Absence of Ketamine Effects on Learning & Memory Following Exposure during Early Adolescence: A Preliminary Report

Journal of Behavioral and Brain Science 2021 Shannon O’brien, David M. Compton, Julianna M. Davis et al.

Traditionally, ketamine was considered useful as a dissociative anesthetic. More recently, ketamine has been examined for its effects as a fast-acting antidepressant, for treatment-resistant depression, and as a non-opiate treatment of chronic pain. Unfortunately, ketamine has enjoyed popularity as a recreational drug among both adolescents and young adults. While some research suggests the use...
