Our research goal is to characterize the neural dynamics in brain networks supporting 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 is on interactions between neurons in the cerebral cortex, basal ganglia and thalamus.
