(A) The ocolumotor delayed response task. Panels represent successive frames of the subject’s screen during the execution of the task. The inset on the right illustrates that the cue may appear at any of eight spatial locations around the fixation point, randomly interleaved during the experiment. (B) Schematic illustrations of two types of neuronal responses during the execution of the task. The top panel illustrates a transient response to the cue that is sustained throughout the delay period. The bottom panel shows a neuron that discharges in accelerating fashion before the onset of the eye movement. Neurons with activation at any combination of task epochs have been reported in the prefrontal cortex and elsewhere.
