Thesis Title:

Which way do I go? Strategic representations in rat prefrontal cortex on spatial decision tasks

Undergraduate Institution and Major/Degree:

Amherst College, BA in Physics and Philosophy, 2004

Major Advisor(s):

A. David Redish

Research Description:

I'm still interested in how we think. We in the large sense, because specifically at this point I'm studying Pre-Frontal Cortex (PFC) in the Rat. PFC has been tied to many functions that are associated with higher level cognitive processing, which is most simply described as what's going on in the animal's head that isn't obviously related to anything going on externally. This is a tricky topic to study, and I'm currently concentrating on the role of the PFC in encoding abstract "strategies" or rules that govern a pattern of behavior over several actions in order to solve a particular task. I've also been involved in some studies exploring the incentive structure of learning internal models in human subjects.
