Visuomotor Functions in the Frontal Lobe.

This review surveys how vision becomes action through the frontal lobe. Signals from extrastriate areas create maps in frontal areas. These maps are shaped by visual features and shaded by goals, values, and experience, and they guide contingent activation of motor circuits to execute coordinated gaze, head, and limb movements. Frontal circuits also support the visual perception of learned objects, events, and actions. Other frontal circuits monitor consequences and exert executive control to improve the effectiveness of visually guided behavior.
