Dr. Gulley's laboratory studies the neurobiological and behavioral consequences of repeated exposure to psychoactive drugs such as amphetamine, cocaine and alcohol. In addition, they investigate the mechanisms of age-related cognitive decline and the use of nutritional supplementation to mitigate that decline. Examples of current research questions addressed by the lab include (1)Are adolescents, compared to adults, more sensitive to drug-induced changes in neural function and behavior? (2) Are there more adverse consequences when drug exposure occurs early in life and are there age-dependent differences in drug-induced neuroadaptations? (3) Can nutritional supplements serve to enhance cognition and/or delay cognitive declines associated with normal aging?
In the lab, Dr. Gulley and his students use behavioral and physiological methods of analysis, both alone and in combination. For behavior, they study drug responses using operant self-administration, conditioned place preference, drug discrimination, and behavioral sensitization techniques. They also use operant food-reinforced responding to assess cognitive behaviors, including impulsivity, behavioral flexibility, attention, and working memory. Physiological measure include in vivo multiple neuron electrophysiology, which allows for the recording of the activity of a large number of brain cells as animals are actively behaving, in vitro electrophysiology, immunohistochemistry, gel electrophoresis, and immunoblotting techniques.

The Psychology Department is very pleased to announce that an all-gender, ADA accessible, family-friendly restroom has been built on the first floor next to the elevators. The department partnered with F&S to construct this new restroom, which is now available to use. Please note that there is an indicator on the door showing whether the restroom is available or in use. Be sure to lock the door while using the restroom, and unlock the door before leaving.
