ABSTRACT
A central problem in neuroscience is the localization of function. Significant progress on this has been made in the oculomotor system. With progress has come the realization that function is usually not localized within a single structure but rather it is distributed across a network of brain areas. In this review, we contrast two brain areas that play a critical role in the planning and initiation of saccadic eye movements: the superior colliculus (SC) and the frontal eye fields (FEF). We describe

role of these structures in the control of visual fixation and initiation of saccadic eye movements by contrasting neural discharges recorded from neurons in each area in a variety of oculomotor tasks.
