WebThe operation is better described in the Wikipedia article Gaussian Filter. First you need to convert your list of points to an image, in essence filling in the line between the points. If you use 8 bits, those cells will have darkness 255 while all others will be 0. Webcal white noise experiments, we generated a random discrete stimulus S(t) that was temporallywhite, drawing the stimulus intensityas an independent Gaussian random variable in each time step. We computed the STA as the average stimulus in the 32 time bins preceding each spike. Fig.1(left)showsaplotoftheactualkernelK …
