Sleep deprivation alters connections in the brain, mouse study finds
Science reports: Lack of sleep wreaks havoc on the brain, making us worse learners and disrupting our memory, among other insults. Now, a study in mice suggests some of these effects could stem from changes in how brain cells are connected to one another. In a paper published today in Current Biology, researchers show that just hours of sleep deprivation reduce how many different types of synapses—the places where neurons meet—there are in brain regions associated with learning and memory….
