The presented sinewave/squarewave light flicker responses of cat horizontal cells confirm the classification into Hn and Hm-units described by Foerster et al. (1977a,b) Expl Brain Res. 29, 347-385. However, we find somewhat higher order filter properties and develop a refinement of the model proposed by Foerster et al. to explain our new results. Using this model further analysis of Hm-unit responses suggests that cat retinal receptors have a smaller temporal bandwidth the smaller the spatial extent of the stimulus. Finally results from Gaussian white noise (GWN) stimulation are compared with those from classical flicker stimuli and Bode-plots. There are strong similarities in the results of these two types of analysis but some interesting differences are also found and discussed.
