A disinhibitory basal forebrain to cortex projection supports sustained attention

Posted by dbos UCSD / Salk

Kavli Affiliate: Edward Callaway | Authors: Shu-Jing Li, Balazs Hangya, Unmukt Gupta, Kyle B. Fischer, James Fitzhugh Sturgill, Edward M. Callaway and Adam Kepe | Summary: Sustained attention, as an essential cognitive faculty governing selective sensory processing, exhibits remarkable temporal fluctuations. However, the underlying neural circuits and computational mechanisms driving moment-to-moment attention fluctuations remain elusive. […]
