前扣带皮层（ACC）和外侧前额叶皮层（LPFC）处理计划和评估行为的互补信息。这至少表明，在行为适应过程中，这两个领域的过程是协调的。我们分析了记录在两个区域的局部场电位在两只猴子执行的问题解决任务，交替探索和重复的行为与具体的预测，神经活动应该揭示interreal协调主要在探索。这两个领域表现出增加高伽玛功率后，错误的勘探和奖励后，在开采。我们发现，高伽玛（60-140赫兹）的功率增加，在ACC之后的LPFC增加，只有在负反馈（错误）或第一次正反馈（正确）在探索期间。两种结构在重复周期内的延迟差异消失。同时记录显示高伽玛功率之间的相关性，在两个领域的反馈，但是，相关性的探索和重复。相比之下，反馈后β（10-20赫兹）功率在ACC和LPFC的相关性更频繁地在重复。总之，我们的数据表明，ACC和LPFC活动之间的协调表示在适应以及稳定的行为期，但不同的模式取决于行为期。
The anterior cingulate cortex (ACC) and the lateral prefrontal cortex (LPFC) process complementary information for planning and evaluating behavior. This suggests at least that processes in these two areas are coordinated during behavioral adaptation. We analyzed local field potentials recorded in both regions in two monkeys performing a problem-solving task that alternated exploration and repetitive behaviors with the specific prediction that neural activity should reveal interareal coordination mainly during exploration. Both areas showed increased high gamma power after errors in exploration and after rewards in exploitation. We found that high gamma (60–140 Hz) power increases in ACC were followed by a later increase in LPFC only after negative feedback (errors) or first positive feedback (correct) during the exploration period. The difference in latencies between the two structures disappeared in repetition period. Simultaneous recordings revealed correlations between high gamma power in the two areas around feedback; however, correlations were observed in both exploration and repetition. In contrast, postfeedback beta (10–20 Hz) power in ACC and LPFC correlated more frequently during repetition. Together, our data suggest that the coordination between ACC and LPFC activity is expressed during adaptive as well as stable behavioral periods but with different modes depending on the behavioral period.
