Acetylcholinesterase (AChE) activity in homogenates from motor and visual cortex of rats reared for 7 weeks in darkness was compared to levels in normally reared and dark reared littermates exposed to 3-h periods of controlled illumination. AChE levels in the visual cortex of animals fitted with light-diffusing scleral contact occluders, and therefore lacking normally organized visual information, were elevated 17% over dark-reared animals, but were not significantly different from levels in animals exposed to lighting conditions permitting detailed pattern discrimination. There were no differences between conditions in motor cortex AChE. We conclude that higher order perceptual processing is not necessary for the light-stimulated increase in visual cortex AChE in the rat.
将在黑暗中饲养7周的大鼠运动皮层和视觉皮层匀浆中的乙酰胆碱酯酶（AChE）活性与正常饲养和黑暗饲养的同窝幼崽在3小时可控光照期后的水平进行比较。装有光扩散巩膜接触眼罩、因此缺乏正常组织视觉信息的动物，其视觉皮层中的AChE水平比黑暗饲养的动物高17%，但与暴露于允许进行详细图案辨别的光照条件下的动物的水平没有显著差异。运动皮层AChE在不同条件下没有差异。我们得出结论，在大鼠中，光刺激引起的视觉皮层AChE增加并不需要高级感知处理。
