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. His research finds that males and females adapt to social stress using different behavioral strategies. He uses immunohistochemistry, sequencing/PCR, and pharmacology to study how a variety of neurotrophin, neurotransmitter, and neuropeptide systems mediate behavioral responses to stress.
