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. http://zabbarob.github.io/measuring-firing-rates-webpage/#:~:text=A%20gaussian%20window%20function%20will%20weigh%20spikes%20that,filters%20and%20their%20window%20functions%20are%20called%20kernels. chris severy https://magicomundo.net

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.
