正电子发射断层扫描（PET）被用来探讨在视觉呈现的物体与不同的任务知觉的运动表征的潜在参与的神经相关。本研究的主要结果是，对象的感知，无论任务（判断的垂直方向，运动想象，和无声的生成的名词或相应的动作动词），与感知的非对象，与rCBF增加在一组共同的皮层区域。枕颞交界区、顶下小叶、SMA固有区、额下回三角部、中央前回背侧和腹侧参与左半球的活动。同侧小脑也受累。这些激活与运动表征已经参与物体感知的想法一致，因此提供了神经生理学证据，证明物体感知自动提供了可以对它们做出的动作。除了这组常见的皮质区域之外，每项任务都涉及特定的区域。(C)2001爱思唯尔科技有限公司版权所有。
Positron emission tomography (PET) was used to explore the neural correlates of a potential involvement of motor representation during the perception of visually presented objects with different tasks. The main result of this study was that the perception of objects, irrespective of the task (judgement of the vertical orientation, motor imagery, and silent generation of the noun or of the corresponding action verb), versus perception of non-objects, was associated with rCBF increases in a common set of cortical regions. The occipito-temporal junction, the inferior parietal lobule, the SMA-proper, the pars triangularis in the inferior frontal gyrus, the dorsal and ventral precentral gyrus were engaged in the left hemisphere. The ipsilateral cerebellum was also involved. These activations are congruent with the idea of an involvement of motor representation already during the perception of object and thus provide neurophysiological evidence that the perception of objects automatically affords actions that can be made toward them. Besides this common set of cortical areas, each task engaged specific regions. (C) 2001 Elsevier Science Ltd. All rights reserved.
