The investigators collected simultaneous recordings using multi-channel electrode arrays attached to the prearcuate gyrus of macaque monkeys who performed a direction discrimination task with fixed stimulus duration.

In the study, 96-channel multielectrode arrays were used to record from neural populations in area 8Ar of the prearcuate gyrus of three macaque monkeys, while they performed a direction discrimination task. The monkey viewed a patch of randomly moving dots for 800 ms on each trial. After a delay period of variable length, the monkey reported the perceived motion direction by making a saccadic eye movement to one of the two available targets. All monkeys were trained on the task before implantation of the recording arrays.

Neural recordings are available for:

• 1206 trials with 219 simultaneously recorded neuron units from Monkey 1
• 1778 trials with 169 simultaneously recorded neuron units from Monkey 2
• 1047 trials with 220 simultaneously recorded neuron units from Monkey 3
