记录是从猫的单个视网膜神经节细胞胞体中进行的，这些猫的视觉皮层区域17和18在出生当天或成年时受损。新生儿损伤导致视网膜中78%的X细胞损失，而成年期的损伤导致22%的损失。Y细胞和W细胞未受影响。在解释视觉皮层损伤后的行为缺陷和神经恢复机制的研究时，需要考虑这种视网膜异常。
Recordings were made from single retinal ganglion cell somas in cats whose visual cortical areas 17 and 18 were damaged on the day of birth or in adulthood. Neonatal lesions produced a 78 percent loss of X-cells in the retina, while lesions made in adulthood produced a 22 percent loss. Y-cells and W-cells were unaffected. This retinal abnormality needs to be considered when interpreting studies of behavioral deficits and neural mechanisms of recovery after damage to the visual cortex.
