The primary research goal of the Z-LAB is to better understand decision making. Making a choice, independent of it being a complex decision about your retirement allocations or which flavor of ice-cream to pick, is the normative consequence of any behavior that is observable.
To understand this process, we combine a multitude of tools that allow us to study neural function of non human primates associated to decision making. We combine single cell electrophysiology, computational modeling of neural responses as well as careful behavioral analysis and ultra high field functional magnetic resonance imaging.
