Rare Cortical Neurons Found to Synchronize Brain Activity and Promote Sleep in Mice
Source Summary
Researchers have identified rare cortical neurons that can synchronize brain activity and promote sleep in mice, challenging the traditional understanding that sleep control originates primarily in deep brain structures. The cerebral cortex, long viewed as a passive follower in sleep regulation, appears to play a more active role than previously believed.
Why it matters
This finding revises the fundamental understanding of how sleep is regulated in the brain, suggesting the cerebral cortex plays a more direct role in sleep control than the traditional model indicated.
