About

In addition to his academic appointment in the Department of Psychology, Brian Trainor is an affiliated faculty member with the UC Davis Center for Neuroscience.   He is also director of the Behavioral Neuroendocrinology Lab at UC Davis. Professor Trainor is a member of several professional organizations, including the Society for Behavioral Neuroendocrinology, the Society for Neuroscience and the Society for Biological Psychiatry. He is also an editorial board member for the journal Hormones and Behavior.

Research Focus

Mood and anxiety disorders are more likely to occur in women, yet most mouse models focus on males. Using the monogamous California mouse, Professor Trainor studies the effects of stress on the brain and behavior. One line of research investigates how oxytocin acts in different brain regions to regulate social approach and social vigilance, a behavior related to social anxiety. A second line of research investigates how adolescent development programs neural mechanisms of behavior related to anxiety.
