In early blind mammals, the deprived visual cortex undergoes anatomical and functional alterations. Its functional role was investigated in the early human blind by using patterns of cortical activation as measured by scalp-recorded event-related slow negative DC potential shifts. The blind showed higher occipital negativity than did sighted persons both during a tactile reading task and a non-reading tactile control task. Results point to a possible role for the blind's visual cortex in tactile processes.
在早期失明的哺乳动物中，视觉被剥夺的视皮层会发生解剖学和功能上的改变。通过头皮记录的事件相关慢负向直流电位偏移测量的皮层激活模式，对早期失明的人类进行了视皮层功能作用的研究。在触觉阅读任务和非阅读触觉控制任务中，盲人的枕叶负电位均高于视力正常者。结果表明，盲人的视皮层在触觉过程中可能发挥作用。
