Neural substrates of action to the object or this specific direct route, however, remain unclear, especially for the connection from the visual pathway to the motor cortex. The study examined this issue by conducting an fMRI experiment, in which two action generation tasks involving pictures of real objects (PA) and the object's nouns (NA) were used, with pictures naming (PN) and covert noun reading (NR) being the control tasks. The result showed that the model predefined for the PCC and precuneus connecting IPL to the posterior-medial frontal cortex dominated over the others (with 0.45 probability), suggesting that the PCC and the precuneus locate at the neural substrates of action to the object. Furthermore, a feasibility study suggests that the neural pathway composed of the V3/MT, precuneus, PCC, and PM (premotor cortex) forms the direct route from perception to action, which also links to the dorsal pathway so that the perception of objects bypasses the semantic ventral pathway and then directly cues actions via the affordance.

前突神经和扣带回皮层在神经动作途径中的作用。

然而,对物体或该特定直接路径的神经作用底物仍然不清楚,尤其是对于从视觉通路到运动皮层的连接而言。该研究通过功能磁共振成像实验研究了这个问题,其中使用了两个动​​作生成任务,涉及真实物体的图片(PA)和物体的名词(NA),其中图片命名(PN)和秘密名词阅读(NR)是控制任务。结果表明,为PCC和预神经连接IPL和后内侧额叶皮层的预定义模型在其他模型上占主导地位(概率为0.45),这表明PCC和预神经位于对对象作用的神经基质上。此外,一项可行性研究表明,由V3 / MT,足前神经,PCC,
