The variation of the response rate of carp retinal ganglion cells to photopic light stimulation was studied. It was found that the standard deviation was independent of the mean of the response rate, even when responses showed compression. This finding is in agreement with a late origin of retinal noise. Implications of the existence of intrinsic constant amplitude retinal noise and of the presence of a mean maintained activity are discussed.
研究了鲤鱼视网膜神经节细胞对明视觉光刺激的反应率变化。发现即使反应呈现压缩状态,标准差也与反应率的均值无关。这一发现与视网膜噪声的晚期起源一致。讨论了固有恒定幅度视网膜噪声的存在以及平均维持活动的存在所带来的影响。
