My name is Ashley Ingiosi, and I started as an Assistant Professor in the Department of Neuroscience at Ohio State University in October 2022. My current research focuses on the role of astrocytes in sleep and sleep homeostasis. This research is funded, in part, by a BRAIN Initiative K99/R00.

A role for astroglial calcium in mammalian sleep and sleep regulation

Ingiosi AM, Hayworth CR, Harvey DO, Singletary KG, Rempe MJ, Wisor JP, Frank MG (2020) Current Biology 30:4373-4383.e7

Video shows astrocyte activity in the brain during non-rapid eye movement sleep (NREMS), rapid eye movement sleep (REMS) and wakefulness (WAKE) as captured with a genetically encoded calcium indicator and miniscope. Video shown is 16x faster than normal speed.
A quick discussion of our main findings can be found here.

Check out our new preprint showing that basal forebrain astrocytes can induce wakefulness without compensatory responses in sleep drive.
Our study exploring the role of astroglial modulation of sleep expression and homeostasis via noradrenergic signaling is published in Clocks & Sleep.
