Marc A. Sommer
Associate Professor of Biomedical Engineering
We study circuits for cognition. Using a combination of neurophysiology and biomedical engineering, we focus on the interaction between brain areas during visual perception, decision-making, and motor planning. Specific projects include the role of frontal cortex in metacognition, the role of cerebellar-frontal circuits in action timing, the neural basis of "good enough" decision-making (satisficing), and the neural mechanisms of transcranial magnetic stimulation (TMS).

- Ph.D. Massachusetts Institute of Technology, 1995
Neuronal circuits of the brain, including recording from single neurons and studying the effects of inactivating or stimulating well-defined brain areas. His goals are to understand how individual areas process signals and how multiple areas interact to cause cognition and behavior. Results from the work are guiding the design of vision-based models and robots.
