Jean-Marie Maddux

Jean-Marie Maddux is a behavioral neuroscientist who investigates the neural
substrates of motivated behavior in a rat model using behavioral, psychopharmacological, and
neurobiological techniques. The broad goals of her research consider the role of associative
learning processes that can contribute to addiction, identify candidate brain areas that allow for
this learning to occur, and explore the involvement of specific neurotransmitter systems in
associative learning and its behavioral output. Her recent work has examined how Pavlovian
cues that accompany alcohol use come to influence behavior, and how nicotine enhances
conditioned responses to an alcohol-associated cue. This work has clinical relevance, as nicotine
and alcohol are highly co-used in human populations, and Pavlovian conditioned stimuli
associated with alcohol can exert a strong influence in the lives of alcohol users. She teaches
courses on behavioral neuroscience, including a seminar on the neuroscience of reward.
