Profile Introduction

Mood and anxiety disorders are more likely to occur in women, yet most mouse models focus on males. Using the monogamous California mouse, Dr. 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.
