Averaged, normalized discharge rates of frontal eye field visually responsive neuron samples aligned to array presentation when the target (thick) or distractors (thin) appear in the response field on correct (left) and error (right) fast (green) and accurate (red) trials for each monkey. Shaded areas represent means ± SE. For each monkey, search errors occur when the visually responsive neurons treat a distractor as if it were the target.
