Abstract

Area V4 has been located in man in the region of the fusiform gyrus on the inferior surface of the occipital lobe. Using multiple dipole source analysis on multichannel EEG recordings of visual evoked potentials to coloured 'Mondrian' stimuli in man, we have confirmed that activity is consistently seen in this area regardless of the retinal area stimulated and have obtained new information concerning its time course. Three different localized centres of activity follow the visual stimulus, with peak latencies of 90, 110 and 160 ms, and arising respectively in the region of visual areas V1, V2/V3 and V4. The time course and character of the V4 dipole activity to a colourless black-and-white Mondrian is indistinguishable from that to the coloured Mondrian, supporting the evidence that the cells of V4 are not exclusively concerned with colour processing.

摘要

在人类中，V4区位于枕叶下表面的梭状回区域。通过对人类视觉诱发电位的多通道脑电图记录进行多偶极子源分析，这些记录是针对彩色“蒙德里安”刺激的，我们已经证实，无论刺激的视网膜区域如何，该区域都会持续出现活动，并且获得了有关其时间进程的新信息。视觉刺激后有三个不同的局部活动中心，峰值潜伏期分别为90、110和160毫秒，分别出现在视觉区域V1、V2/V3和V4区域。V4区对无色黑白蒙德里安图案的偶极子活动的时间进程和特征与对彩色蒙德里安图案的活动无法区分，这支持了V4区细胞并非仅与颜色处理有关的证据。
