의식이란 무엇인가? 뇌에서 "느낌"은 어떻게 만들어지는가 — 과학이 풀지 못한 가장 어려운 질문 | 뇌과학 6편

The brain is, after all, just a circuit. So why does "feeling" arise from it? Consciousness — the hardest unsolved question in neuroscience. Five key facts in this video: 1. 1995 — Philosopher David Chalmers posed the "Hard Problem": how does subjective experience arise from information processing? Thirty years later, no answer. 2. 1974 — Thomas Nagel asked, "What is it like to be a bat?" Even mapping every neuron in a bat's brain wouldn't answer it. 3. Integrated Information Theory (IIT) and Global Workspace Theory (GWT) — the two most influential attempts to explain consciousness, asking from different angles. 4. 1920s Moscow — Solomon Shereshevsky, the man who could remember everything. His perfect memory destroyed his life. Forgetting, it turns out, is essential to consciousness. 5. We still don't know exactly how anesthesia turns off consciousness — despite hundreds of millions of surgeries every year. 00:00 Opening 01:08 Chapter 1: At This Moment, You Are Conscious 05:59 Chapter 2: Where Does "Feeling" Begin? 11:55 Chapter 3: Two Attempts to Explain Consciousness 19:07 Chapter 4: The Man Who Remembered Everything — Shereshevsky 25:32 Chapter 5: When Consciousness Turns Off — Sleep, Dreams, Anesthesia 29:56 Chapter 6: How Far Does Consciousness Reach?
