Unsupervised competition between two presynaptic neurons. (a) Synaptic evolution (adaptation) under temporal spiking configuration of two Poisson neurons (N 1 and N 2) and single postsynaptic neuron (N 3) is plotted. The schematic of the network is depicted in the inset. N 1 and N 2 fire Poisson spikes at 5 Hz, and N 3 spikes accordingly. (b) Phase plane analysis on synaptic bifurcation on the trials in (a)—indicated by different colors. The winning synapse was chosen at random. The same parameters as tabulated in Tables 2 and 3 were used.
