Biology Monday Seminar

4:00 pm Virtual

Katherine Nautiyal, PhD, Assistant Professor, Psychological and Brain Sciences, Dartmouth College, will speak on "The neural and behavioral basis of impulsivity"

I’m interested in how we exert self-control, and reasons why we might fail to be able to control our behavior. Our lab studies one aspect of this by focusing on understanding the neural circuits that underlie impulse control. Impulsive behavior is characterized by acting on a whim or difficulty delaying gratification and is a key component in many every-day behaviors such as making healthy eating choices or saving money. Dysregulated impulsivity plays a major role in a number of psychiatric disorders including ADHD, binge eating, substance use disorders, and behavioral addictions. We use a number of neurobiological and behavioral approaches in mouse models to understand how serotonin modulates the neural circuits that contribute to the regulation of impulsive behavior. Our work uses genetic and viral manipulations of serotonin signaling, careful behavioral assessment, and in vivo one photon calcium imaging. Recent work has focused on the serotonin 1B receptor (5-HT1B), and its role in reducing impulsivity by influencing reward value.

Persons from the Amherst College community who wish to attend should please register with Biology ADC Karen Racz, who will provide the Zoom link to the seminar.
