In this session, we'll be focusing on the things that happen in our brain when we sleep.

When we think about sleep, it’s easy to imagine it as the brain simply shutting down for the night. But neuroscience shows us that sleep is actually one of the most active and coordinated states the brain ever enters. During sleep, entire networks shift their patterns of communication. Regions like the cortex, hippocampus, thalamus, hypothalamus, and brainstem all reorganize their activity in very specific ways.

Studying sleep helps us understand memory consolidation, emotional regulation, and even why certain brain disorders develop. In other words, sleep is not a passive state, but a dynamic biological process that reshapes the brain every single night!
