The lab studies how neural representations support behaviors like decision making. They approach this question by recording the electrical activity of neurons as rats perform behavioral tasks. Electrophysiological techniques are augmented with optogenetics and computational analyses. Current projects are exploring how interactions between the hippocampus and the orbitofrontal cortex support decision making, the encoding of spatial goals, and the formation of neural representations for abstract stimulus spaces.
