How does our brain enable us to pay attention selectively to certain important objects, and to ignore other, irrelevant ones? What happens in the brain when we make important decisions? Dr. Sridharan's research focuses on understanding the neural basis of cognitive phenomena such as selective attention and decision-making. To achieve this goal, his lab adopts a highly interdisciplinary approach. This includes measuring brain activity with high-density electrophysiology (EEG) and functional neuroimaging (fMRI) in subjects performing attention-demanding tasks that require making complex decisions. In addition, non-invasive neurostimulation techniques (transcranial electric and magnetic stimulation, tES/tMS) are employed to perturb brain activity and study the effects on behavior. The ultimate goal of Dr. Sridharan's research is to develop a unified framework to understand the neural computations by which cognitive phenomena emerge, and how they shape human behavior.
