Research description

Our research goal is to show how brain networks enable cognitive control and conscious awareness.

The lab investigates three major research questions. First, how do we execute cognitive control, including selective attention, rule-guided behavior, mental set shifting and memory processes? Second, what are the neural differences between conscious, anesthetized and sleep states? Third, how does the brain code information and regulate information transmission?

We combine neuroimaging and electrophysiology to investigate these questions. We map brain networks using functional MRI and diffusion MRI. Next, we simultaneously record neural activity from interconnected network sites in behaving macaques (single-units, local field potentials, microstimulation) and human subjects (intracranial electrocorticography). Our focus in on interactions between the cerebral cortex and the thalamus.
