The findings offer new insights into how sleep prepares our brain to learn.
Neuroscientists have revealed new details about how our brains are reset when we sleep. But their findings open new questions about the role of sleep in the second half of the night.Getting enough sleep is essential for our mental and physical well-being, but scientists are only just beginning to figure out what is happening in our brains when we sleep.
'In their new study, published in the journal Nature, Rihel and his team used specially designed zebrafish to study the activity of brain cells during the sleep-wake cycle. Specifically, they were interested in the connections between the brain cells, called synapses, which allow information to be passed from one cell to another.After several sleep-wake cycles, the team saw that the brain cells consistently gained more connections during the waking hours, and lost them during sleep.
