"All simulations are carried out using a network of 1000 spiking neurons described in detail by Izhikevich (2006), who provides the MATLAB and C code. The code is also available on the authorfs web page www.izhikevich.com."

"This low frequency of firing is important for the "low probability" of sequential spikes to fall within the STDP time window by chance"

"The time course of a typical unreinforced synapse looks like a random walk near 0."
