Introduction The capacity to understand the others’ emotional states, particularly if negative (e.g. sadness or fear), underpins empathic and social brain. Patients who cannot express their states experience isolation loneliness, exacerbating distress. We investigated feasibility of detecting non-invasive scalp-recorded electrophysiological signals that correspond recalled sadness, fear, joy for potential classification. Methods neural activation patterns 20 healthy right-handed participants were studied using an technique. Analyses focused on N400 component Event-related potentials (ERPs) recorded during silent recall subjective states; Standardized weighted Low-resolution Electro-magnetic Tomography (swLORETA) was employed source reconstruction. study classified individual brain linked recollection three distinct into seven regions interest (ROIs). Results Statistical analysis (ANOVA) magnitude values revealed existence a common circuit, as well areas specifically active sad, happy fearful states.

Diverse explanations or theories of consciousness are arrayed on a roughly physicalist-to-nonphysicalist landscape essences and mechanisms. Categories: Materialism Theories (philosophical, neurobiological, electromagnetic field, computational informational, homeostatic affective, embodied enactive, relational, representational, language, phylogenetic evolution); Non-Reductive Physicalism; Quantum Theories; Integrated Information Theory; Panpsychisms; Monisms; Dualisms; Idealisms; Anomalous Altered States Challenge Theories. There many subcategories, especially for Each explanation is self-described by its adherents, critique minimal only clarification, there no attempt to adjudicate among theories. The implications assessed with respect four questions: meaning/purpose/value (if any); AI consciousness; virtual immortality; survival beyond death. A Landscape Consciousness, I suggest, offers perspective.

The nervous system is a product of evolution. That is, it was constructed through long series modifications, within the strong constraints heredity, and continuously subjected to intense selection pressures. As result, organization functions brain are shaped by its history. We believe that this fact, underappreciated in contemporary systems neuroscience, offers an invaluable aid for helping us resolve brain's mysteries. Indeed, we think consideration evolutionary history ought take place alongside other intellectual tools used understand brain, such as behavioural experiments, studies anatomical structure functional characterization based on recordings neural activity. In introduction, argue importance evolution highlighting specific examples ways theory can enhance neuroscience. rest theme issue elaborates point, emphasizing conservative nature evolution, important consequences transitions occurred our history, which considerations shed light issues ranging from mechanisms fundamental principles organization.

Examination of cognition has historically been approached from language and introspection. However, human language-dependent definitions ignore the evolutionary roots brain mechanisms constrain their study in experimental animals. We promote an alternative view, namely that cognition, including memory, can be explained by exaptation expansion circuits algorithms serving bodily functions. Regulation protection metabolic energetic processes require time-evolving computations enabling organism to prepare for altered future states. Exaptation such was likely exploited exploration organism's niche. illustrate gives rise a cognitive map, turn, environment-disengaged computation allows mental travel into past (memory) (planning).

Over the last decades, interdisciplinary field of affective sciences has seen proliferation rather than integration theoretical perspectives. This is due to differences in metaphysical and mechanistic assumptions about human phenomena (what they are how work) which, shaped by academic motivations values, have determined constructs operationalizations. An assumption on purpose can be used as a teleological principle guide construction common set assumptions—a framework for research.

Abstract In 1993, the British Journal of Clinical Psychology published my paper titled ‘Defence and safety: Their function in social behaviour psychopathology’. The highlights that to understand people's sensitivity threat, we also need their ability identify what is safe. This offers an update on these concepts, highlighting distinctions were implicit but not clearly defined at time. Hence, seeks clarify between: (i) threat detection response, (ii) safety seeking, (iii) safeness (iv) non‐social functions forms. Threat response are prevent or minimize harm (e.g., run from a predator fire).
