Abstract
Traditionally action and perception are treated in isolation, and are generally thought to be implemented by distinct brain modules in that sensory areas transform sensory signals into perception while (pre-)motor areas control action planning and execution. In this talk, this traditional framework will be challenged by the findings that the visual cortex can be distinctively activated by eye-movements and the primary motor cortex can be distinctively activated by visual stimuli. First, the study shows that the inferior occipital temporal cortex, areas thought to represent face and house images, can be activated by eye-movement sequences without any image input. Then the results show that the primary motor cortex can be activated by reward-predictive visual stimuli even when this motor activation is counterproductive to getting reward. Further results show how this inappropriate motor activation can be overcome by inhibitory control. Taken together, these findings suggest interactions between perceptual system and motor system in the brain, and shed light on the mechanism of self-control disorders.
