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. 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 …

WebMar 21, 2006 · Abstract. Tuning curves are widely used to characterize the responses of sensory neurons to external stimuli, but there is an ongoing debate as to their role in sensory processing. Commonly, it is assumed that a neuron's role is to encode the stimulus at the tuning curve peak, because high firing rates are the neuron's most distinct responses. http://zabbarob.github.io/measuring-firing-rates-webpage/ WebFor example, given the standard model of neural firing rates following Poisson statistics, the Poisson distribution is well approximated by a Gaussian distribution for firing rates … postoperativ bedingt
