The localization of neural processes contributing to face perception was studied in two patients using event-related field potentials (ERPs) recorded from subdural strips and functional magnetic resonance imaging (fMRI). Despite the differences in the physiological bases of the two techniques, and in the tasks used to elicit activation, good correspondence was obtained in the anatomical patterns of activation. Face-specific ERPs (N200s) and fMRI activation by faces occurred at the same locations in the right ventral extrastriate region of both patients, and in a similar region of the left hemisphere of one patient. Some discrepancies were noted in the pattern of activation which may reflect the adequacy of the tasks in identifying face-specific as opposed to face-sensitive processing, and in the differential sensitivity of the methods to the temporal course of face processing.
使用从硬膜下条带记录的事件相关场电位 (ERPs) 和功能磁共振成像 (fMRI)，研究了有助于面孔感知的神经过程在两名患者中的定位。尽管两种技术的生理基础以及用于引发激活的任务存在差异，但在激活的解剖模式中获得了很好的一致性。两名患者的右侧腹侧外纹状区以及一名患者左侧半球的相似区域均出现了特定于面孔的 ERPs（N200s）和 fMRI 激活。在激活模式上存在一些差异，这可能反映了任务在识别特定于面孔的处理与对面孔敏感的处理的充分性，以及方法对面孔处理的时间过程的不同敏感性。
