WebSep 1, 2024 · Generally, the firing rate may depend on the time and history of the point process. If the firing rate λ(t) depends on time, then the process is non stationary.The part of the rate that depends on history takes into account the detailed interactions between past spike times and the current ones (Johnson, 1996).One example of such interactions is … WebAug 18, 2024 · Let T be our time period and r be the firing rate. The firing rate is equal to the probability of an individual neuron firing times the number of neurons, divided by the time period T. Thus r = P N / T and P = r T / N. Notice that if r T is kept constant and N increases, P must decrease. Substituting this into our formula for p ( n), we get.
