Neural systems in learning, motivation, and attention

My research used a variety of behavioral and neurobiological techniques to study associative learning in rodents. As a result of associative learning, environmental cues acquire the ability not only to elicit particular goal-directed responses, but also to evoke sensorily-rich representations of their associates, alter the allocation of attention in the control of current action and subsequent learning, and endow previously neutral events with motivational significance. My empirical research examined commonality in the processing of real events and their associatively-activated representations, the role of confirmations and violations of learned expectancies in attention, and mechanisms by which cues related to the presentation and removal of food acquire the ability to override normal satiety systems and control binge eating in the absence of energetic needs for consumption. I am especially interested in the roles of amygdala and hypothalamus in modulating functions of cortical and striatal systems, and computational approaches to understanding functional connectivity in human brains.
