Understanding Cortical Activity During Sleep and Wakefulness

Understanding Cortical Activity During Sleep and Wakefulness

Sleep and wakefulness influence both cognitive and overall health, yet the mechanisms regulating them are poorly understood. The National Eye Institute has awarded Renata Batista-Brito, Ph.D., a five-year, $2.6 million grant to investigate the role played by long-range inhibitory neurons of the cerebral cortex during sleep and wakefulness.

Dr. Batista-Brito and her colleagues hypothesize that the activity of cortical long-range inhibitory neurons that express SST and nNOS—the so-called SST/nNOS neurons—generate slow cortical rhythms that regulate the transition from the brain’s highly active UP state to its less-active DOWN state. Since those rhythms are believed to affect brain functions including attention, memory, and sensory processing, the activity of SST/nNOS neurons may therefore profoundly influence our sleeping-and-waking lives.

Dr. Batista-Brito is an assistant professor in the Dominick P. Purpura Department of Neuroscience, of genetics, and of psychiatry and behavioral sciences at Einstein. (1R01EY034617-01)
