Scientific lectures: Neuromodulation of Brain States

The arousal construct underlies a spectrum of behaviors that include sleep, exploration, feeding, sexual activity and adaptive stress. Pathological arousal conditions include stress, anxiety disorders, and addiction. In the past few years we have used optogenetics to interrogate neuronal circuits underlying transitions between arousal states. In particular, I will talk about two new circuits identified in our laboratory: one predicts the onset and duration of REM sleep with unprecedented precision; another induces sleep in response to inflammatory cytokines. I will also present a novel method that displays cortex-wide fluctuations in membrane voltage using TEMPO imaging. Finally, I will discuss noninvasive neuromodulation methods for sleep intervention.
