The Nautiyal Lab studies the neural basis of impulsivity. Impulsive behaviors are characterized as lacking in lack self-control. The ability to delay gratification and suppress responses are both facets of a multi-dimensional construct of impulsivity. Dysregulated impulsive behavior is a key component in a number of psychiatric disorders including ADHD, binge eating, substance use disorders, and behavioral addictions like gambling disorder. Our focus is on the serotonergic modulation of the neural circuits that control impulsive and aggressive behavior. We use a number of approaches to better understand how the brain controls self-control.
