Darlene Skinner

 

 

The main goal of my research is to relate brain function to behavior. One major focus of my research is spatial learning. Current studies in spatial learning are addressing the issue of what animals really learn about their spatial environment. Do they use proximal cues, distal cues, geometry, or path integration (or some combination) to locate a hidden goal. Another area of interest is conditional discrimination learning. The same stimulus can have a very different meaning depending on the context in which it is presented. I am interested in identifying the neuroanatomical substrates that might be important in these types of learning. Current studies are examining the role of the hippocampus and related cortical structures in both spatial and conditional learning.
