Paul Mermelstein is the Head of the Department of Neuroscience. His laboratory researches sex differences in the brain. Specifically, how sex hormones (estrogen in females, testosterone in males) alter the synaptic connections in the brain to influence motivated behaviors. He and his team have discovered that when estrogen concentrations rise in females, their vulnerability to abuse addictive drugs increases. They are seeking to determine the mechanisms by which estrogens impart vulnerability to drug addiction, and ways to circumvent these changes in brain plasticity, ultimately in hopes of improving therapeutic interventions.
