TED-Ed: What causes hallucinations? - Elizabeth Cox

The video explores hallucinations, focusing on Charles Bonnet syndrome, where visually impaired individuals experience vivid hallucinations. It discusses the brain's role in constructing perceptions, even with sensory deprivation. The video also examines how drugs like LSD and psilocybin cause hallucinations by affecting serotonin receptors, similar to mechanisms in schizophrenia. Understanding these phenomena can reveal insights into how our brains perceive the world.
