Abstract
The responses of dorsal lateral geniculate body units to striate cortex and optic chiasm stimulation were examined in cats immobilized with d-tubocurarine. A high correlation between antidromic responses to striate cortex and orthodromic responses to optic chiasm stimulation was found (r=0.895; P=0.01). 9% of neurons responded antidromically to optic chiasm stimulation indicating the existence of centrifugal fibres in the optic nerve. The functional significance of time dispersion of the afferent volley in visual system is discussed.
摘要
在使用d -筒箭毒碱麻痹的猫身上，研究了外侧膝状体背侧单元对纹状皮质和视交叉刺激的反应。发现对纹状皮质的逆向反应与对视交叉刺激的顺向反应之间存在高度相关性（r = 0.895；P = 0.01）。9%的神经元对视交叉刺激有逆向反应，这表明视神经中存在离心纤维。文中讨论了视觉系统中传入冲动时间离散的功能意义。
