Dr. Henriksen's laboratory studies the functional organization of neural circuits where intrinsic capacities for both normal and abnormal brain functions reside. To understand how the brain initiates, promotes, and alters behavior, our goal is to understand the hierarchy that neuronal circuits and their chemical messengers have in producing appropriate responses to external and internal sensory events. This approach requires in vivo studies and is best described as a "systems" analysis of behavior. His colleagues and he employ anatomical, neuropharmacological, electrophysiological, molecular and behavioral tools to reveal the hierarchies of the cellular components of brain circuits underling behavioral integration and functional pathology. They study animals whose central nervous system is either intact but one that can be compromised by either viral infection, genetic manipulations or by molecular engineering.
