John Neumaier, MD, PhD

Personal Statement

​My clinical interests include diagnosis and  psychopharmacology of complex mood and anxiety disorders and psychosis. My research program investigates the molecular neuroscience of behavior using animal models with a focus on the involvement of the serotonin system and the neurocircuitry and plasticity involved in stress and addiction.

My lab uses rat and mouse models to investigate stress and addiction mechanisms. The lab is unusual because we pursue a very broad range of methods, including molecular, cellular, neuroanatomical, and behavioral levels of organization. We have focused on serotonin receptors historically but increasingly we are using novel molecular and genetic tools to dissect the involvement of key neural circuits in behavioral models of stress and/or addiction.

The main strategies include a range of behavioral models, intersectional transgenic and viral-mediated gene transfer manipulations of gene expression, neuropharmacology, engineered receptors (DREADDs), fiber photometry, calcium imaging, two-photon microscopy, RNAseq and RTqPCR (using RiboTag pull-down). We are trying to push the envelope in developing and using methods that allow us very precise manipulations or readouts from specific pathways such as the projections from nucleus accumbens to ventral tegmentum or lateral habenula to dorsal raphe nucleus. We are also exploring the role of microglia, the innate immune cells in the brain, during early stages of drug and alcohol withdrawal in advance of typical activation of neuroinflammation.
