The variation in the light responses of carp retinal ganglion cells is independent of response amplitude.
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.
