Analysis of Network Activity in Spiking Networks with Synaptic Depression


Spiking neural networks with short term plasticity (STP) of the synapses shows dynamical behavior (population spikes) that is not observed in networks without STP. The analytical approach to the activity of spiking neuronal networks has been developed extensively in the last two decades, using the Fokker-Planck approach. Unfortunately this approach is not well suited to study networks with STP. Here I will demonstrate an alternative approach to the analysis of network stability, based on the analysis of the inter-spike interval distribution. O this approach STP is easily incorporated, and I will show how it can e used to determine under which condition population spikes occur.
