antisaccade

antisaccade

A saccade that is directed toward a stimulus.

antisaccade 

A voluntary eye movement made in the direction opposite to the side where a stimulus is presented. The subject is asked to fixate a small dot for some time. A stimulus is then presented to one side and the subject is asked to inhibit a reflex eye movement towards it but to make a saccade in the opposite direction. Analysis of the errors and/or latencies of the antisaccades indicate dysfunction in the frontal lobe, which controls the saccadic eye movements. See saccadic eye movement.
