Both S1 and S2 proteins resulted in inflammation in a delayed ... WebWe would like to think of the neural response function as a random process. The neural response function is completely equivalent to a list of the spike times in the spike train. Nevertheless, it is useful for re-expressing sums over spikes as integrals over time. For example, we can write the spike count, the number of spikes fired between ...
