The relations between the SI cell and the inputs continue to hold even if the inputs are not exactly periodic. Compared to Figs. 5(b), 6 and 7, the interpulse intervals for each input are now random, independent of one another. Their distribution is chosen to be normal with mean equal to the nominal period (here 40 Hz for input-1 and 16.357 Hz for input-2), and standard deviation equal to 5% of the mean. (a) The SI cell still fires in phase with input-1, at a firing rate equal to that of input-2. (b) As we vary the input-2 frequency, the SI firing rate follows closely. Dashed line: diagonal. (c), (d) The FS cell fires in response to either input, while the SI cell fires only in response to input-1 pulses, and as long as these pulses arrive inside an interval of time after an input-2 pulse (see also caption of Fig. 7)
