He is also the Director of Neuroscience Program in the College of Liberal Arts. Dr. Parikh’s research generally concerns neuromodulation of cognitive processes specifically those involved in attention and executive functions. A particular focus of his work is to delineate neurochemical signaling mechanisms that regulate functional interactions between the prefrontal cortex and other cortical and subcortical regions, and how alterations in discrete neurochemical circuits impact top-down cognitive control of behavior during the aging process and following chronic use of psychoactive drugs.
