The structure that integrates impulses for eye-hand coordination is:: (A) Superior colliculus, (B) Frontal eye field, (C) Pretectal nucleus, (D) Area 17
Answer is A. Superior colliculus integrates impulses for eye-hand coordination to control rapid directional movements of the two eyes. VISUAL PATHWAY Other impoant areas of the brain involved in visual pathway: Suprachiasmatic nucleus of the hypothalamus, to control circadian rhythms; Pretectal nuclei in the midbrain, to elicit reflex movements of the eyes to focus on objects of impoance and to activate the pupillary light reflex; Superior colliculus, to control rapid directional movements of the two eyes; and Ventral lateral geniculate nucleus of the thalamus and surrounding basal regions of the brain, to help control some of the body's behavioral functions.
