Hanks Lab | Neurology Research

The central goal of our lab is to elucidate the neural mechanisms that underlie decision making. Decision making occurs at the interface between cognition and behavior, so we believe that understanding its neural basis holds the promise of exposing the general principles of neural computation that support cognition. Our primary approach is to train rodents to perform complex behavioral tasks that are carefully designed to allow us to develop mathematical descriptions of the underlying decision processes. We employ high-throughput, automated training methods to provide a steady pipeline of subjects for these studies. We harness the rapidly expanding toolkit of cutting-edge molecular and cellular techniques available for rodents, such as optogenetics, in combination with high-density neural recordings to both measure and manipulate neural activity across a range of brain regions, including cortical and subcortical networks. We use the knowledge gained from these experiments to develop and constrain circuit-level descriptions of the computations that underlie decision making. The nature of our research is highly collaborative, and the UC Davis neuroscience community provides a wealth of opportunities for these collaborations.
