Environmental epigenetics examines how chemical exposures, nutritional states, and ecological stressors modify gene expression without altering DNA sequence — through DNA methylation, histone modifications, and non-codin

Z_1_01 — ENCODE Project, Non-Coding DNA & Epigenetics

The human genome is ~3.2 billion base pairs long, but only ~1.5% encodes proteins. The remaining ~98.5% was once dismissed as "junk DNA." The ENCODE Project (2003–present) revealed that at least 80% of the genome has bio

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.
