Chronic patterned optogenetic stimulation
WebJul 11, 2024 · Using chronic oCIs, we show the reliability of optogenetic stimulation over weeks and find that it potently cues avoidance behavior. We characterize the response of single neurons of the auditory cortex to oCI stimulation. Finally, we show that oCI restores some auditory function in a gerbil model of ototoxic deafness.
