Why Your Exhausted Brain Starts Hearing Voices

Right now, your body might be begging you to sleep — and you're ignoring it. You've blinked a dozen times in the last minute without noticing, and somewhere in the back of your skull, your brain has started to misbehave. It isn't just slowing down. It's inventing things. In this video, you'll discover why exhaustion makes your brain generate its own sounds and images, and why psychologists call these moments hypnagogic hallucinations. You'll learn why your auditory cortex is one of the last regions of the brain to fall asleep, and what happens when a starved brain starts feeding on itself. You'll see what research from Nature Neuroscience, the Salk Institute, the University of Zurich, and the Walter Reed Army Institute of Research reveals about the voices, knocks, and whispers your mind produces in the dark. And you'll find out why this strange twilight state once kept your entire species alive on the savanna — and why it's proof your brain is loyal to you, not broken.
