| | To reveal the neural basis of behavioral decision, we examined cell activity in the lateral, medial, and orbital parts of the prefrontal cortex (PFC) of monkeys (n=3) performing a visually cued GO/NO-GO task. We quantitatively analyzed visual, motor, and reward information represented along the trial. The reward information was primarily represented in the 3 parts of the PFC when the visual cue was presented. Then the motor information grew up toward the GO/NO-GO decision in the medial and lateral PFC while the reward information was maintained. These results suggest that the behavioral decision is made goal-directedly in PFC. |
