K_4_05 — Synchronicity, Meaningful Coincidence, and Acausal Connection

Synchronicity—defined by Carl Jung as "meaningful coincidence with no causal connection"—represents one of the most provocative concepts at the intersection of psychology, physics, and philosophy. Developed through Jung'

K_4_13 — Mirror Neurons and Social Cognition

Mirror neurons are a class of neurons, first discovered in the early 1990s in the premotor cortex (area F5) of macaque monkeys by Giacomo Rizzolatti, Vittorio Gallese, and colleagues at the University of Parma, that fire

K_4_07 — Biofield Science — Electromagnetic and Subtle Energy Research

Biofield science investigates the electromagnetic, acoustic, and hypothesized "subtle energy" fields associated with living organisms, spanning a spectrum from rigorous biophysics to highly contested alternative medicine

K_4_02 — Stigmata, Faith Healing, and Psychosomatic Phenomena

The human body can do things under the influence of belief that should not be physically possible according to conventional medical models. The placebo effect — a "sugar pill" producing measurable physiological changes —

K_4_15 — Shared Death Experiences

Shared death experiences (SDEs) are reported phenomena in which a person who is physically healthy — typically a family member, caregiver, or bystander present at a death — describes experiencing some or all of the featu

K_4_08 — Parapsychology — Experimental Research on Psi Phenomena

Parapsychology is the scientific study of purported psychic phenomena — telepathy, clairvoyance, precognition, and psychokinesis (collectively termed "psi") — using experimental methods. Originating with J.B. Rhine's car

K_2_04 — Attention and Awareness

Attention and awareness are intimately linked yet dissociable aspects of consciousness. Attention — the selective processing of some information at the expense of other information — is a fundamental bottleneck in human

K_2_15 — Glial Cells and the Tripartite Synapse: The Brain's Other Half

Glial cells (neuroglia) — comprising astrocytes, oligodendrocytes, microglia, and NG2 glia in the central nervous system, plus Schwann cells and satellite cells in the peripheral nervous system — constitute approximately

K_2_05 — Unconscious Processing

The cognitive unconscious — mental processes that influence behavior, emotion, and decision-making without reaching conscious awareness — is one of the most empirically robust phenomena in psychology and neuroscience. Fa

K_2_18 — Meditation Neurophysiology

Neuroimaging studies of meditation have produced a convergent picture: focused attention practices increase prefrontal and anterior cingulate cortex activity, open monitoring practices decrease default mode network (DMN)

K_2_06 — Neurofeedback and Brain Training

Neurofeedback — the real-time display of brain activity (typically EEG) to enable individuals to learn self-regulation of neural dynamics through operant conditioning — has been investigated since the pioneering work of

K_2_10 — Neural Entrainment: External Rhythmic Brain Synchronization

Neural entrainment — the process by which rhythmic external stimuli (sound, light, tactile vibration, or electromagnetic fields) synchronize the timing of neural oscillations in the brain — is a well-established neurophy

K_2_19 — Sleep & Dream Neuroscience — Topology of States

Sleep occupies approximately one-third of human life (~26 years for an average lifespan of 79 years) and constitutes a radically altered state of consciousness whose neurobiological mechanisms, evolutionary function, and

K_2_00 — Neuroscience Brain: Subfolder Summary

K_2_09 — Neuroscience of Free Will

The neuroscience of free will centers on experiments testing whether conscious intention precedes or follows the neural preparation for action. Benjamin Libet's landmark 1983 experiments showed that the brain's "readines

K_2_13 — Attention Networks: Dorsal, Ventral, and Salience Systems

Attention — the selective allocation of processing resources to particular stimuli, locations, or tasks — is among the most studied phenomena in cognitive neuroscience and is intimately linked to consciousness: what we a

K_5_10 — Theories of Self: No-Self, Minimal Self, Narrative Self

The self — the sense of being a unified, continuous subject of experience — is one of the most fundamental yet puzzling features of consciousness. Who or what is the "I" that sees, thinks, remembers, and acts? Theories o

K_5_04 — Neuroscience of Belief

Belief — the mental state of holding something to be true — is a cornerstone of conscious experience, shaping perception, memory, emotion, decision-making, and behavior. The neuroscience of belief has revealed that belie

K_5_18 — Working Memory: Cognitive Architecture and Executive Function

Working memory (WM) is the cognitive system responsible for temporarily holding and manipulating information during complex tasks such as reasoning, language comprehension, and decision-making. Distinguished from passive

K_5_20 — Psychoneuroimmunology: Mind-Body-Immune Connections

Psychoneuroimmunology (PNI) — the study of interactions between psychological processes, the nervous system, and immune function — has established that the mind directly influences immune defense and that immune activity
