To perform the<unk> , an individual is asked to fixate on a motionless target (such as a small dot). A stimulus is then presented to one side of the target. The individual is asked to make a saccade in the direction away from the stimulus. For example, if a stimulus is presented to the left of the motionless target, the patient should look toward the right. Failure to inhibit a reflexive saccade is considered an error. Neurologic disorders affecting both the frontal cortex or the basal ganglia have shown impaired performance on the<unk> . These include schizophrenia, Huntington's disease, Parkinson's disease, and progressive supranuclear palsy. Additionally, disseminated brain disease such as Alzheimer's disease or AIDS dementia also have an increased number of errors.
