Marlene Cohen is a principal investigator at the University of Chicago where she leads a lab dedicated to understanding how visual information is perceived and utilized by the brain's cognitive processes. The lab's research focuses on how information is encoded in the brain and how attention can be strategically applied to prioritize crucial information in real-time. By employing a combination of advanced methodologies, including single and multi-electrode electrophysiology, psychophysics, and computational techniques, Cohen investigates the dynamics of neuronal groups in the visual pathway and their influence on behavior. Critical to her approach is the recording of neuronal responses, which provides insights into the available visual information and how it informs decision-making. Through her work, Cohen aims to unveil the intricate relationships between neuronal activity, cognitive states, and perceptual decision-making in primates, contributing to a deeper understanding of the neural foundations of vision and behavior.
