Dr. McCarthy is a leading neuroscientist who has made significant discoveries related to gender differences and the brain. Herseminal research focuses on the influence of steroid hormones on the developing brain with a special emphasis on understanding the cellular mechanisms that establish sex differences—that is, the numerous, novel mechanisms (including roles for prostaglandins, endocannabinoids, amino acid transmitters, and multiple enzymes) by which steroids permanently organize the developing brain differently in males and females. Dr. McCarthy conducted some of the first studies on how steroid hormones can imprint epigenetically on the developing brain to organize differences between males and females in adult physiology and behavior.
More recently, her laboratory generated a paradigm shift in understanding of sexual differentiation of sexual behavior with the discovery that the feminization program of development requires suppression of the masculinization program via DNA methylation, and that steroid hormones emancipate the male gene expression profile by reducing activity of DNA methylating enzymes. Her laboratory has also studied inflammatory and immune-mediated sex differences in the brain, sensitive periods in brain development, neurogenesis in the postnatal brain, and the role of GABA in brain differences. By increasing understanding of how the brain develops differently in males and females, Dr. McCarthy has revealed both naturally occurring variation as well as highlight points of vulnerability and nodes for intervention in treatment of developmental neuropsychiatric disorders with a gender bias.
