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.
我们在癫痫患者执行面部分类任务时，对其面部选择区域进行电刺激。电刺激对面部分类产生干扰，但增加视觉信号可以恢复面部分类。更重要的是，电刺激对面部分类的干扰仅限于面部选择电极，且干扰的程度与面部选择电极的敏感性呈正相关。这些结果有力地支持了这样一种假设，即面部选择区域与面部感知之间存在直接的因果关系。
