Abstract

The 'solitary cell' of Meynert has been studied during postnatal development in the normal cat and in kittens reared either with unilateral or bilateral eyelid suture, or in the dark. Following dark-rearing there was a marked reduction in the frequency with which Meynert cells could be distinguished compared with the normal, but the effects of eyelid suture were mild. These observations were confirmed in a semi-quantitative study and they indicate that this distinct morphological class of neurone in the striate cortex of the cat may be affected by abnormal visual experience during the critical period.

摘要

在正常猫以及单眼或双眼睑缝合饲养或黑暗饲养的小猫的出生后发育过程中,对迈内特(Meynert)的“孤立细胞”进行了研究。与正常情况相比,黑暗饲养后,可区分出的迈内特细胞的频率显著降低,但眼睑缝合的影响较小。这些观察结果在一项半定量研究中得到了证实,它们表明,猫纹状皮层中这种独特形态类别的神经元可能在关键期受到异常视觉经验的影响。
