In particular it is shown that networks of spiking neurons are, with regard to the number of neurons that are needed, computationally more powerful than these other neural network models. This result has further been generalized for analog inputs and arbitrary reasonable response functions.
Voltage is integrated until threshold is reached.
After a refractory period, integration starts again from rest potential. Doc 12 Analysis of synfire chains - Herrmann, Hertz et al. The graph only includes citing articles where the year of publication is known.
