Abstract:

The paper distinguishes the use of visual cues to guide reaching and grasping, and the ability to learn to associate arbitrary sensory cues with movements. Using positron emission tomography (PET), we have shown that the arbitrary association of visual cues and movements involves the ventral visual system (prestriate, inferotemporal and ventral prefrontal cortex), the basal ganglia and the dorsal premotor cortex. Using functional magnetic resonance imaging (fMRI), we have shown that the evoke...
