Conflict-dependent activity modulation of two OFC cells. Cellular activity (aligned at reward delivery) was modulated by the conflict experienced in the course of obtaining the reward. A, In this cell, the neuronal response to reward had two consecutive components and was the largest in free-reward trials followed by low-conflict and then high-conflict trials. B, In this second cell, response to reward was the highest in high-conflict trials. See Figure 12 for an additional example cell.
