Spatio-temporal coding that combines spatial constraints with temporal sequ
encing is of great interest to brain-like circuit modelers. In this paper w
e present some new ideas of how these types of circuits can self-organize,
We introduce a temporal correlation rule based on the time difference betwe
en the firings of neurons. With the aid of this rule we show an analogy bet
ween a graph and a network of spiking neurons, The shortest path, clusterin
g based on the nearest neighbor, and the minimal spanning tree algorithms a
re solved using the proposed approach.
