Abstract

Saccades are very rapid eye movements allowing us to explore the visual world. Although most of the time unconscious, the programming of each saccade implies a complex decision which depends upon both the perceptual context and the intentions of the subject. The cerebral cortex is critically involved in deciding where, when and in which sequence we move the eyes. Using sophisticated experimental designs, such as the learning of sequences of saccades, has revealed that besides a core fronto-parietal circuit, prefrontal, cingulate, and mediotemporal regions seem critically involved in higher level oculomotor control. Understanding precisely the cortical networks associated to different components of ocular movements can certainly be very useful to characterize, test, and eventually detect various kinds of neurological pathology.
