Abstract

Networks of spiking neurons are very powerful and versatile models forbiological and artificial information processing systems. Especially formodelling pattern analysis tasks in a biologically plausible way thatrequire short response times with high precision they seem to be moreappropriate than networks of threshold gates or models that encode analogvalues in average firing rates. We investigate the question how neurons canlearn on the basis of time differences between firing times. In particular,we provide learning rules of the Hebbian type in terms of single spikingevents of the pre- and postsynaptic neuron and show that the weightsapproach some value given by the difference between pre- and postsynapticfiring times with arbitrary high precision.
