Summary:
- This article discusses a new study that has mapped the activity of the cortex during sleep. The researchers used advanced imaging techniques to observe the brain's activity patterns as people slept.
- The study found that different regions of the cortex, the outer layer of the brain responsible for higher-order functions, show distinct patterns of activity during different stages of sleep. This suggests the cortex plays a more active role in sleep than previously thought.
- Understanding the cortex's involvement in sleep could lead to new insights into the functions of sleep and potentially help develop better treatments for sleep disorders.
