我们在癫痫患者执行面孔分类任务时，对他们的面孔选择区域进行电刺激。面部分类受到电刺激的干扰，但通过增加视觉信号恢复。更重要的是，面孔分类的电刺激干扰仅限于面孔选择性电极，干扰的量与面孔选择性电极的敏感性呈正相关。这些结果有力地支持了这一假设，面孔选择区有一个直接的因果关系，以面孔知觉。(C)2013 Elsevier Inc. All rights reserved.
We electrically stimulated the face-selective area in epileptic patients while they were performing a face-categorization task. Face categorization was interfered by electrical stimulation but was restored by increasing the visual signal. More importantly, face-categorization interference by electrical stimulation was confined to face-selective electrodes, and the amount of interference was positively correlated with the sensitivity of the face-selective electrodes. These results strongly support the hypothesis that the face-selective area has a direct causal link to face perception. (C) 2013 Elsevier Inc. All rights reserved.
