Serotonin neurons are mainly localized to the raphe nuclei of the brainstem, but their axons are widely distributed throughout the nervous system and have a ubiquitous role in physiological processes and behavior. Adding to this complexity is the diverse array of high-affinity receptors that bind serotonin, each having distinct effects on behavior. My lab is using a variety of intersectional tools for targeting, manipulating and monitoring the activity of discrete serotonin circuits in order to gain insight into how these circuits are disrupted in psychiatric disorders. We are also investigating the role of enteric serotonin in brain disorders such as autism and generalized anxiety disorder. The ultimate goal of this work is to identify new therapeutic targets for these often intractable conditions.
