The behavioral task. In each trial, five distractors (+) and five potential targets (T) were presented. One T, the target, had a fluid reward linked to it such that, when the monkey looked at it for 500 ms within 8 s, it obtained the reward. The stimuli were arranged so that, when the animal looked at one stimulus (small black circle), another stimulus was usually centered in the receptive field of the neuron (black oval). The gray trace shows an example eye movement path.
