Research Statement

Dr. Neigh's research uses animal models to provide insight into the role of cerebral vascular and metabolic compromise in the generation of affective and cognitive disorders. Her work focuses on periods of increased plasticity and susceptibility to insults such as adolescence and late life. The work in Dr. Neigh's lab is multidisciplinary and attends to the interplay among the nervous, cardiovascular, endocrine, reproductive, and immune systems. In addition, her work spans multiple levels of analysis from assessment and manipulation of gene expression, to imaging in rodents, to behavioral analysis.
