Overview of the Lab

The Laboratory on Neurobiology of Compulsive Behaviors aims to understand the causes of substance use disorder (SUD). More specifically, we focus on the neuronal mechanisms that drive the high motivation to consume substances of abuse in SUD, and the compulsive aspects of SUD that generate a loss of control over consumption. Given that only a portion of individuals who are exposed to substances of abuse develop SUD, we are particularly interested in understanding the mechanisms that create vulnerability to SUD. The long-term goal of this research is to improve the treatment and prevention of SUD.

Our recent studies suggest that the behaviors characterizing SUD may develop from an interaction between the effects of substances of abuse and the individual’s pre-existing neurobiology. To further probe this hypothesis, we are investigating the synaptic and circuit mechanisms that mediate reward-seeking, reinforcement, and the loss of control over consumption.  We are carrying out a wide array of behavioral analysis and in vivo manipulations of neuronal activity to dissect the alterations to brain circuit function associated with SUD behaviors. Moreover, we are taking advantage of the individual variability of wild-type mice and leveraging the power of genetically engineered mouse models to understand what makes some brains more vulnerable to develop compulsive behaviors toward abused substances.
