Visual memory + movement–preparation neurons and comparison with visual memory neurons. (A,C) Discharge of a representative SEF visual memory + movement–preparation neuron. Cue 1 motion–direction was presented as 100% correlation (A) and 0% correlation (C). (A1,A2) Go trials when cue 1 motion was leftward (A1) and rightward (A2). (A3,A4) No-go trials when cue 1 motion was leftward (A3) and rightward (A4). (B) Time course of mean (±SE) discharge modulation of visual memory neurons (red, n = 13) and visual memory + movement–preparation neurons (blue, n = 22) during go trials in their preferred directions. In (C1,C2), go trials were sorted into leftward pursuit (C1) and rightward pursuit (C2) during action period. (C3), no-go trials. (D,E) Plot mean (±SE) choice probability time course of 10 SEF visual memory + movement–preparation neurons during go trials based on whether the monkeys pursued in the preferred directions of individual neurons during delay 2 when cue 1 was presented with 0% correlation (D) and 100% correlation [(E), black]. Green traces in (E) are mean (±SE) choice probability time course of the same 10 neurons when a stationary pattern was presented at cue 1 (0°/s). For further explanation, see text.
