在1例2岁起失明的6岁儿童中，正常波幅和正常波形的枕叶电位不仅由漫射光闪光诱发，而且还通过低空间频率的棋盘格和正弦格栅图形交替诱发。计算机断层扫描显示，除主要视觉投影区外，枕叶均被破坏。因此，在人类中，视觉关联皮质的破坏可能会导致视觉丧失，而部分保留了模式诱发的枕叶电位。
In a 6 yr old child, blind since the age of 2 yr, occipital potentials of normal amplitude and waveform were evoked not only by diffuse light flashes but also by alternating checkerboard and sinusoidal grating patterns of low spatial frequency. Computerized tomography demonstrated destruction of the occipital lobes except of the primary visual projection area. Thus, in man, destruction of visual association cortices may result in loss of vision with partial preservation of pattern-evoked occipital potentials.
