Abstract

Magnification, the relative size of the neural representation of a portion of the visual field, decreases more rapidly with increasing visual field eccentricity in striate cortex than in the retinal ganglion cell layer of the owl monkey (Aotus trivirgatus); the proportion of the cells in striate cortex devoted to central vision is much larger than the comparable proportion of retinal ganglion cells. Magnification in striate cortex is a power function of magnification in the retinal ganglion cell layer. A formula for convergence (ganglion cells to cortical neurons) follows from this relationship.

摘要

放大率，即视野一部分的神经表征的相对大小，在纹状皮层中随着视野偏心率的增加而比夜猴（Aotus trivirgatus）视网膜神经节细胞层下降得更快；纹状皮层中 devoted to central vision 的细胞比例比视网膜神经节细胞的相应比例大得多。纹状皮层中的放大率是视网膜神经节细胞层中放大率的幂函数。从这种关系可以得出一个汇聚公式（神经节细胞到皮层神经元）。

需注意，原文中“devoted to central vision”表述不太准确，可能有误，准确表述或许是“devoted to central visual field”之类，但按照要求翻译如上。
