| Research Abstract |
Activity of single neurons in the macaque lateral prefrontal cortex mainly represented signals related to movement that indicates the choice when the choice was determined by endogenous preference. Activities of ensemble of the neurons also represent the reward type the subject was about to choose and the neurons differed from those that signaled the target reward type when it was determined by the external cue. Therefore, neurons in the lateral prefrontal cortex changed their activity dependent on the way how the choice to be determined and may serve selection of the appropriate action.
