Cortical mechanisms of saccade generation from execution to decision.
Several cortical areas are involved in the control of ocular motor behavior, but little is known about the cognitive processes occurring prior to saccade triggering. The use of functional brain imaging allows a better understanding of the networks involved specifically in distinct processes of saccade generation. The use of sophisticated visual stimulation paradigms in functional imaging studies suggests that the decision process of where to look when faced with visual alternatives is subserved by a prefrontoparietal network, including the dorsolateral prefrontal cortex.
