Neurochemical regulation of sleep and wakefulness, mechanisms of general anesthesia, mechanisms underlying the relationship between sleep disruption and psychiatric disorders.
My research program aims to identify the neurochemical mechanisms and brain regions that regulate behavioral states such as sleep, wakefulness, and anesthesia. The goals of my laboratory are to identify overlapping neuronal circuits regulating the interactions between sleep, anesthesia, mood, cognition, and pain. The work focuses on acetylcholine, GABA, and hypocretin/orexin as neurotransmitters, and the pontine reticular formation, basal forebrain, and prefrontal cortex as brain regions important for behavioral state control.
