Research in our lab focuses on how the visual system processes motion. We rely on visual motion as a model system to understand how neurons transform simple sensory signals into representations used during perception, cognition, and action. We employ a variety of psychophysical and physiological techniques to address these issues. Specifically, we focus on (1) how motion and depth information is combined to represent the 3D direction of motion, (2) how visual motion signals are accumulated and remembered to inform perceptual decisions, and (3) how visual imagery and expectations about motion interact with low-level sensory processing.
