Research in our laboratory seeks to understand vision and cognition by combining measurements of behavior with neural measurements made using functional MRI. A main topic currently under investigation is visual plasticity - how cortex can change with experience. Within this domain we are examining effects of altered environments, perceptual training, and visual expertise.
