Abstract
Sex differences in many non-reproductive behaviors have been described in rodents and humans. Among the behaviors and responses that are sexually dimorphic in the rat are: activity, aggression, pain, and taste sensitivity, food intake and body weight regulation, learning and retention of certain kind of mazes, avoidance response, taste aversion, and performance on schedule reinforcement. In humans, similar sex differences are seen in verbal fluency, performance of spatial tasks, verbal memory tests, and fine motor skills. Depression and depressive diseases are more common in women while substance abuse and antisocial behavior is more common in men. Immunologically, the female sex is stronger, and there are clear gender differences in outcomes to same treatment modalities. This review examines the sexual dimorphism in non-reproductive behavior. Specifically gender differences in central mechanisms of food intake regulation including gender differences in hypothalamic monoaminergic systems influencing food intake.
