Major Research Theme
Our research focuses on the regulation of sleep and wakefulness, with an emphasis on understanding the neurobiology of narcolepsy. Orexin (hypocretin)-containing neurons of the hypothalamus promote wakefulness, and individuals with narcolepsy have a loss of these cells resulting in excessive daytime sleepiness. One of our long-term goals is to identify the mechanisms regulating the activity of orexin neurons. We have found that these neurons are active during wakefulness, and we are now determining the neural and humoral factors that control this activity. Using innovative neural tracing techniques, we are identifying the projections to the orexin neurons, and we are studying the behavior of orexin knockout mice to determine whether orexin influences the circadian timing of sleep/wake behavior. To determine which brain regions mediate the wake-promoting effects of orexin, we have produced mice in which we can knock out or knock in orexin receptors within specific brain regions. Clinical studies include neuropathologic studies of the brains of people with narcolepsy, measurement of sleep-related changes in orexin concentration, and studies of metabolism and glucose regulation in narcolepsy. |
