Neuroscience Focus Groups:
My research uses a combination of behavioral and functional magnetic resonance imaging (fMRI) techniques to understand the neural mechanisms of object recognition and other high level visual processes. Some of the questions currently being addressed include: How does the visual system group features into objects and surfaces? How does the visual system recognize objects across changes in viewpoint? How is perceived depth and image size combined in the visual cortex? Does perceived object size affect retinotopic maps in early visual cortex? How does attention change neural tuning and sensitivities? In addressing these questions, we take a general theoretical approach that the abilities of the visual system result from using an inferential process that combines prior knowledge and expectations with incoming sensory data to form a “best guess” of the object and surface structure of the environment.
