View full lesson: https://ed.ted.com/lessons/the-left-brain-vs-right-brain-myth-elizabeth-waters

Your brain hallucinates your conscious reality | Anil Seth

Right now, billions of neurons in your brain are working together to generate a conscious experience — and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen?

Caffeine helps us feel alert, focused, and energetic, even if we haven’t had enough sleep — but it can also raise our blood pressure and make us feel anxious. So how does it keep us awake? Hanan Qasim shares the science behind the world’s most widely used drug.
