Dr. Sylvia Fitting: Behavior and Neurocognition in HIV-1
Using state-of-the-art live cell imaging, electrophysiology, and behavioral techniques, Dr. Fitting’s laboratory is developing a better understanding of how cellular function is affected by drug abuse ± HIV/HIV-1 protein infection. Human immunodeficiency virus type 1 (HIV-1) infects the brain and many individuals suffer from HIV-1 associated neurocognitive disorders. Dr. Fitting determines the role of endocannabinoids in neuroAIDS and her experiments increasing endocannabinoid signaling will determine if it will be protective in models with neuronal damage.

Dr. Jessica Cohen: Neural Flexibility Changes Throughout Typical Development
Human are remarkably adaptable – we can instinctively change a planned course of action when the unexpected occurs, rapidly learn new skills, and deftly compensate for loss of functioning. This flexibility in behavior and control is present throughout the lifespan. Dr. Cohen investigates how distinct brain networks interact and reconfigure when confronted with changing contexts and how neural flexibility contributes to flexibility in control and the ability to learn.

Dr. Stacey Daughters: Stress, Reward, and Substance Use Outcomes
Stress and other forms of negative affect often precede relapse to substance use. Using a computerized behavioral task, Dr. Daughters examine indvidiual differences in the ability to tolerate stress and negative affect. Individuals with a substance use disorder – who can tolerate stress and negative affect during this task – are significantly more likely to stay in substance use treatment and maintain successful abstinence.
