Abstract

Visual response properties of superior collicular neurons of normal hamsters were compared with those of animals reared from birth to adulthood in either total darkness or with stroboscopic illumination. Directional selectivity was markedly reduced only in the strobe-reared animals, thus demonstrating visual plasticity in a system that develops apparently normally without visual experience.

摘要

将正常仓鼠上丘神经元的视觉反应特性与在完全黑暗环境中或频闪照明下从出生饲养至成年的动物的视觉反应特性进行了比较。仅在频闪饲养的动物中,方向选择性显著降低,从而证明了在一个显然在没有视觉经验的情况下正常发育的系统中存在视觉可塑性。
