Dorsal Striatum and Decision Making: Implications for Addiction
Post Doctoral Associate, University of Pennsylvania
Undergraduate Institution and Major/Degree:
- University of Nebraska at Omaha
I am interested in multiple decision-making systems theory and how it relates to addiction. I have two projects that I'm working on. 1) Recording simultaneously in dorsal medial and dorsal lateral striatum and measuring information processing about flexible and habitual actions. 2) Using decision-making systems theory to understand and improve upon certain types of addiction treatment.
