Astrocyte calcium activity throughout sleep cycle (VIDEO)

Washington State University

Caption

Video of astrocyte activity in the brain during a single sleep cycle, captured using a fluorescent calcium indicator and miniature microscope. The footage shows dynamic changes throughout the cycle as it transitions through non-rapid eye movement sleep (NREMS), rapid eye movement sleep (REMS), and wakefulness (WAKE). Video shown is 16 times faster than normal speed.
