Figure 33

Post Stimulus Time Histogram (PSTH) of a cat ON-center ganglion cell response to a very dim stimulus, delivering only five quanta of light to the cornea in a 10-msec flash. The "Count Gate" is a 200-msec long interval in which impulse responses were counted, either in the dark or after the dim flash. Reproduced from Barlow et al. (68).
