K_3_09 — Minimal Consciousness and the Threshold of Sentience

Where does consciousness begin? This question — the problem of the threshold of sentience — is one of the most challenging in consciousness studies because it requires identifying what KIND of physical system is minimall

K_3_06 — Disorders of Consciousness: Coma, Vegetative State, and Minimal Consciousness

Disorders of consciousness (DoC) — coma, vegetative state (now termed unresponsive wakefulness syndrome/UWS), and minimally conscious state (MCS) — represent some of the most challenging clinical and philosophical proble

Most neuroscience focuses on chemical synapses, but the brain also uses electrical synapses formed by connexin-36 gap junctions — direct cytoplasmic channels that pass ions and small molecules between neurons. These prov

The question of when consciousness emerges during human development — whether prenatally, at birth, or gradually through infancy — is one of the most consequential in consciousness studies, with direct implications for f

K_3_16 — Anesthesia and Consciousness: What Going Under Reveals

General anesthesia provides a unique experimental window into consciousness: the ability to reversibly abolish and restore awareness in a controlled clinical setting. Despite over 175 years of practice since William T.G.

K_3_04 — Anesthesia and Consciousness

General anesthesia — the reversible, drug-induced abolition of consciousness — is one of medicine's greatest achievements and, paradoxically, one of its least understood. Approximately 350 million surgical procedures per

Memory and consciousness are deeply intertwined — memory provides the continuity of experience that creates a sense of self persisting through time, while consciousness provides the subjective context within which memori

The Orchestrated Objective Reduction (Orch-OR) theory — proposed by Nobel laureate Roger Penrose and anesthesiologist Stuart Hameroff — suggests consciousness arises from quantum computations in microtubules within neuro

Higher-order (HO) theories of consciousness propose that a mental state becomes conscious not by virtue of its intrinsic properties but because it is the target of a higher-order mental representation — a thought, percep
