Gaussian convoluted firing rate
WebGaussians Closed under Convolution. the Fourier transform of a Gaussian is Gaussian, and in § D.2 that. the product of any two Gaussians is Gaussian. Therefore, it follows … WebNov 21, 2024 · Kernel-based firing rate estimation. Let t 1, t 2, ⋯, t n be a sequence of spike times (i.e. a spike train) which can be expressed mathematically as (1) where δ(t) is Dirac function and n is the total number of spikes. The underlying rate function also known as firing rate, λ(t), can be estimated by using kernel smoothing, a method which …

WebApr 16, 2016 · 2. I want to calculate the convolution F ∗ G of two Gaussian functions without resorting to Fouritertransforms: F ( t) := exp ( − a t 2), G ( t) := exp ( − b t 2) a, b > 0. But intuitively I expected the convolution to result again in a non constant function. Can anyone find my mistake / confirm that this calculation is correct? Let Ω ...

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 … WebDec 17, 2024 · Learn more about convolution, gaussian, normal distribution, exponential .

WebSep 8, 2014 · The first and most commonly used definition of a firing rate refers to a temporal average. An experimentalist observes in trial k the spikes of a given neuron … WebNov 9, 2011 · The distribution of in vivo average firing rates within local cortical networks has been reported to be highly skewed and long tailed. The distribution of average single-cell inputs, conversely, is expected to be Gaussian by the central limit theorem. This raises the issue of how a skewed distribution of firing rates might result from a symmetric …
