当在看不见的步行者的关节上观看一些点光时，可以唤起人们对移动人类的生动看法。已经发现，这种特殊的生物运动感知能力涉及后颞上沟（STSP）。但是，在日常生活中，也可以使用声学提示来识别人类的运动。在本研究中，我们通过稀疏的采样功能MRI设计调查了聆听脚步时人类运动感知的神经底物。我们首先展示了一个听觉注意网络，该网络共享了以前在视觉注意范式中发现的额叶和顶叶区域。其次，在听觉皮层（Heschl的回和平面颞叶）中观察到激活，可能与低级声音处理有关。最引人注目的是，在先前使用视觉输入报道的时间生物运动区域重叠的STSP区域中证明了另一种激活。因此，我们建议，无论感觉方式输入如何，STSP区域的一部分可能是参与人类运动识别的超大型区域。 （c）2005 Elsevier Inc.保留所有权利。
A vivid perception of a moving human can be evoked when viewing a few point-lights on the joints of an invisible walker. This special visual ability for biological motion perception has been found to involve the posterior superior temporal sulcus (STSp). However, in everyday life, human motion can also be recognized using acoustic cues. In the present study, we investigated the neural substrate of human motion perception when listening to footsteps, by means of a sparse sampling functional MRI design. We first showed an auditory attentional network that shares frontal and parietal areas previously found in visual attention paradigms. Second, an activation was observed in the auditory cortex (Heschl's gyrus and planum temporale), likely to be related to low-level sound processing. Most strikingly, another activation was evidenced in a STSp region overlapping the temporal biological motion area previously reported using visual input. We thus propose that a part of the STSp region might be a supramodal area involved in human motion recognition, irrespective of the sensory modality input. (c) 2005 Elsevier Inc. All rights reserved.
