Investigation of Locus Coeruleus Function in Sustained Attention

Summary

The norepinephrine-producing locus coeruleus (LC) is thought to be central to a wide array of cognitive functions, like attention and goal pursuit, and has been implicated in dysfunctions including attention deficit hyperactivity disorder and schizophrenia. The goal of this proposal is to develop methods that permit measurement of activity in the human LC. Because the LC is small and located in the pons, the Investigators will use high resolution magnetic resonance imaging techniques tailored to the brainstem environment, including neuromelanin-sensitive images shown to delineate the LC, combined with pharmacological manipulation to confirm the location of functional activity.
