72 Hours of No Sleep-What Happens to Your Brain？🧠

Описание: You think you’re awake, but your brain is already eating itself. 🧠 After 72 hours, your neurons begin to cannibalize their own connections to survive the toxic buildup. Watch the full timeline of biological structural failure.


Detailed Scientific Breakdown: What actually happens to the human brain during extreme sleep deprivation? This video explores the neurobiological transition from chemical fatigue to structural collapse.

Metabolic Crisis (24h): The buildup of Adenosine and why executive function impairment at this stage is chemically identical to a 0.1% Blood Alcohol Concentration (BAC).

Biological Cannibalism (48h): The immune response known as Astrocytic Phagocytosis. Specialized astrocytes begin to consume synaptic terminals.

Cognitive Blackout (72h): Glymphatic system failure and the intrusion of the REM cycle into waking hours, leading to sensory distortion and "Waking Dreams."

Irreparable Debt: Permanent neuronal loss in the Locus Coeruleus and why sleep debt cannot be "repaid."
