Visually evoked potentials (VEPs) were compared in 7 normally reared cats (N cats) and 9 cats deprived of pattern vision during postnatal period. In 4 deprived cats (D cats) recording was done immediately after deprivation period which lasted from 6 to 24 months. In 5 cats (DE cats) 6 months of deprivation was followed by 4-18 months of visual experience. Two stimuli were used: a large stationary stimulus (a 30 per 30 degrees grating pattern illuminated by flash) and a small moving stimulus (a smaller grating pattern was located in different parts of visual field and illuminated by a moving 1 per 4 degrees light slit). The VEPs were recorded in the marginal, suprasylvian, ectosylvian and sigmoid gyri. As compared with N cats, in D cats the VEPs in all cortical areas were of simpler form, more variable and of greater amplitude. Moreover, in contrast to N cats, in D cats the VEPs were of similar amplitude when evoked from the contra or homolateral visual field. However, results in DE cats showed that these changes are largely reversible.
对7只正常饲养的猫（N组猫）和9只在出生后被剥夺模式视觉的猫的视觉诱发电位（VEP）进行了比较。在4只剥夺视觉的猫（D组猫）中，剥夺期持续6至24个月，剥夺期结束后立即进行记录。在5只猫（DE组猫）中，先剥夺视觉6个月，然后给予4至18个月的视觉体验。使用了两种刺激：一种是大的静止刺激（一个30×30度的光栅图案，由闪光灯照亮）和一种小的移动刺激（一个较小的光栅图案位于视野的不同部位，由一个每4度移动一次的1度光缝照亮）。在边缘回、上薛氏回、外薛氏回和乙状回记录VEP。与N组猫相比，D组猫所有皮质区域的VEP形式更简单、更易变且振幅更大。此外，与N组猫不同的是，D组猫从对侧或同侧视野诱发的VEP振幅相似。然而，DE组猫的结果表明，这些变化在很大程度上是可逆的。
