从猕猴的大细胞(MC)和小细胞(PC)通路的神经节细胞收集到稳定的放电，而它们的感受野被4.7度稳定的黄光照度均匀地照亮。确定了这些放电的平均速率、变异系数、间隔分布、序列相关系数和功率谱。这些结果使人们能够估计猕猴神经节细胞放电中的噪声功率，从而确定不同幅度的视觉信号将如何受到驻留在其放电中的噪声的影响。尽管MC和PC通路细胞的放电之间存在一些小的序列相关性，但它们的放电可以被认为是相当准确的更新过程的结果。与猫神经节细胞的放电一样，猕猴的神经节细胞放电可以被认为具有大约伽马分布的间隔。MC和PC通路细胞的稳定放电在它们的统计数据中显示出相当大的重叠，尽管存在微小但显著的差异。
Steady discharges were collected from ganglion cells of the magnocellular (MC) and parvocellular (PC) pathways of the macaque while their receptive fields were uniformly illuminated with a 4.7-deg steady yellow light of photopic illuminance. The mean rates, coefficients of variation, interval distributions, serial correlation coefficients, and power spectra of these discharges were determined. The results presented permit one to estimate the noise power in the discharges of macaque ganglion cells and hence determine how visual signals of different amplitudes will be affected by the noise resident in their discharges.Although there was some small serial correlation in the discharges of both MC- and PC-pathway cells, their discharges can be considered to result from renewal processes with reasonable accuracy. As with the discharges of cat ganglion cells, macaque ganglion cell discharges can be considered to have approximately gamma-distributed intervals. Steady discharges of MC- and PC-pathway cells show considerable overlap in their statistics, although small but significant differences are present.
