This study examined sex differences in categorization of facial emotions and activation of brain regions supportive of those classifications. In Experiment 1, performance on the Facial Emotion Perception Test (FEPT) was examined among 75 healthy females and 63 healthy males. Females were more accurate in the categorization of fearful expressions relative to males. In Experiment 2, 3T functional magnetic resonance imaging data were acquired for a separate sample of 21 healthy females and 17 healthy males while performing the FEPT. Activation to neutral facial expressions was subtracted from activation to sad, angry, fearful and happy facial expressions. Although females and males demonstrated activation in some overlapping regions for all emotions, many regions were exclusive to females or males. For anger, sad and happy, males displayed a larger extent of activation than did females, and greater height of activation was detected in diffuse cortical and subcortical regions. For fear, males displayed greater activation than females only in right postcentral gyri. With one exception in females, performance was not associated with activation. Results suggest that females and males process emotions using different neural pathways, and these differences cannot be explained by performance variations.

This is a report of a pilot project designed to explore the feasibility of using the clinical Adult Service Psychiatry Consultation-Liaison Program at the University of Michigan as the locus for teaching medical gerontology to psychiatric and medical/surgical house officers and medical students. The goals, general techniques, educational content, and implementation procedures are described. Evidence was obtained that teaching medical gerontology through the program is both feasible and effective. Since a nonphysician gerontologist implemented the clinically based teaching program, the project is an example of the possibilities inherent in a multidisciplinary clinical teaching program.
