Monitoring actions is essential for goal-directed behavior. However, as opposed to short-lasting, and regularly reinstating monitoring functions, the neural processes underlying continuous action monitoring are poorly understood. We investigate this using a pursuit-tracking paradigm. We show that beta band activity likely maintains the sensorimotor program, while theta and alpha bands probably support attentional sampling and information gating, respectively. Alpha and beta band activity are most relevant during the initial tracking period, when sensorimotor calibrations are most intense. Theta band shifts from parietal to frontal cortices throughout tracking, likely reflecting a shift in the functional relevance from attentional sampling to action monitoring. This study shows that resource allocation mechanisms in prefrontal areas and stimulus-response mapping processes in the parietal cortex are crucial for adapting sensorimotor processes. It fills a knowledge gap in understanding the neural processes underlying action monitoring and suggests new directions for examining sensorimotor integration in more naturalistic experiments.
监测行为对于目标导向行为至关重要。然而，与短暂且定期恢复的监测功能不同，持续动作监测背后的神经过程却鲜为人知。我们使用追踪范式对此进行研究。我们发现，β波段活动可能维持感觉运动程序，而θ波段和α波段可能分别支持注意力采样和信息门控。在初始追踪期，当感觉运动校准最为强烈时，α波段和β波段活动最为相关。在整个追踪过程中，θ波段从顶叶皮质转移至额叶皮质，这可能反映了功能相关性从注意力采样向动作监测的转变。这项研究表明，前额叶区域的资源分配机制和顶叶皮质中的刺激-反应映射过程对于适应感觉运动过程至关重要。它填补了理解动作监测背后神经过程的知识空白，并为在更自然主义的实验中研究感觉运动整合提出了新方向。
