放大倍率，即部分视野的神经表征的相对大小，随着视野偏心率的增加，在纹状皮层中比在视网膜神经节细胞层中下降得更快；纹状皮层中负责中枢视觉的细胞比视网膜神经节细胞的比例要大得多。纹状皮层的放大倍数是视网膜神经节细胞层放大倍数的幂函数。从这种关系可以得出一个趋同公式（神经节细胞到皮质神经元）。
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.
