Supranuclear control of ocular motility.

Ocular motor behavior is dictated by visual demands. The entire brain is involved in programming and executing of eye movements. Gaze shifts performed under natural conditions require an elaborate supranuclear coordination between various motor and sensory mechanisms. Recently, a wealth of novel data emerging from animal studies along with functional imaging in humans expanded and modified traditional schemes of premotor organization of the ocular motor system. In this review, types of eye movements that provide clear and stable vision are delineated, neuroanatomical basis of ocular motor control is considered, and the clinical disorders of supranuclear motility are discussed.
