以往的人类视觉运动不协调监测研究强调额-顶叶网络的作用，并发现右侧背外侧前额叶(DLPFC)和右侧顶部下小叶显着激活。利用功能磁共振成像，本研究调查了参与明确监测运动意图与视觉和/或本体感觉信息之间不一致性的大脑区域，特别是额顶网络。在同相双手动作中，参与者自己的手的静态图像被随机插入到动作的实时视觉反馈中，以在实际表现和视觉输入之间产生不匹配。我们任务的结果与以前的研究结果相似，因为在不一致条件下观察到右侧DLPFC的活性比在一致条件下更大。然而，与以前的研究相比，DLPFC簇的解剖位置被发现在更腹侧的区域。以右侧DLPFC为种子区的全脑心理生理交互作用分析表明，与双侧背侧运动前皮质、颞中回(V5区)和右侧吻侧顶下小叶(PFT区)的功能连接显著增强。
Previous human studies on monitoring for visuomotor incongruence emphasized the contribution of the fronto-parietal network and revealed significant activation of the right dorsolateral prefrontal cortex (DLPFC) and the right rostral inferior parietal lobule. Using functional MRI, this study investigated the brain regions involved in explicit monitoring for incongruence between motor intention and visual and/or proprioceptive information, particularly focusing on the fronto-parietal network. During in-phase bimanual movements, a static image of the participant’s own hands was randomly inserted within real-time visual feedback of the movements to produce a mismatch between the actual performance and the visual input. The results of our task were similar to those of previous studies, in that greater activity was observed in the right DLPFC during incongruence conditions than during congruence conditions. However, the anatomical location of the DLPFC cluster was found in a more ventral region, compared with previous studies. Psychophysiological interaction analysis for the entire brain, using the right DLPFC as a seed region, indicated significantly greater functional connectivity with the bilateral dorsal premotor cortex, middle temporal gyri (area V5), and right rostral inferior parietal lobule (area PFt).
