In the Peng lab, we apply a multidisciplinary approach including electrophysiology, calcium imaging, optogenetics, chemogenetics, pharmacology, viral-based neural tracing, molecular biology, and mouse genetics to study the neurobiology of sleep. Currently, we aim to: 1) map the brain circuits controlling the transition between sleep and wakefulness; 2) identify genes or signaling molecules that initiate and maintain sleep. A complementary study is to use next-generation sequencing techniques to identify genetic variants associated with human sleep disorders, such as insomnia and hypersomnia. In order to study the function of sleep, we examine how sleep, more importantly sleep deprivation affects brain functions and cognitive behaviors, such as sensory perception, learning, and memory.
