RESEARCH
The Sreenivasan Lab is interested in how the brain forms and implements goals. Our primary focus is the neurobiological basis of working memory, which is the process that allows us to actively hold on to information over brief periods. Working memory underlies our ability to communicate, problem solve, and think abstractly. In the lab, we combine neuroimaging and behavioral studies in healthy and patient populations in order to gain insight into how working memory and other elements of goal-directed behavior are implemented in the human brain.

Research areas include: 
How are multiple working memory representations organized in parallel? Working memory likely involves multiple parallel representations distributed across the brain, but it is not clear what the purpose of this organization is. We aim to uncover the joint and unique contributions of parallel working memory representations to behavior as well as understand how they interact.

How are memories converted into a coherent behavioral response? Working memories are richer than previously imagined. Converting these representations into a simple (e.g., match/non-match) behavioral response is not a trivial feat. We aim to elucidate the processes and brain mechanisms by which rich working memories are converted to point estimates in response space.

How do top-down signals leverage the spatiotopic organization of the human brain? Topographic maps are found in multiple regions, including parietal and prefrontal control areas. We propose that interregional spatiotopically-specific signals are critical for organizing multiple elements of cognition. We aim to characterize the nature and limitations of these signals and demonstrate their importance for working memory and attention.
