Even Awake, Our Brains Rest and Activate During Sleep

This new discovery blurs the line between being asleep and awake . Credit: Pixabay Scientists have made a groundbreaking discovery: a small region of our brain shuts down briefly to take microsecond-long naps while we're awake. Interestingly, these same areas become active during sleep. These findings could provide crucial insights into neurodevelopmental and neurodegenerative diseases associated...
