Stability and Competition in Multi-spike Models of Spike-Timing Dependent Plasticity
Fig 4
A. Schematic illustration of spike interactions in the suppression model, in which the effect of the presynaptic spike in a pair is suppressed by a previous presynaptic spike (top), and the effect of the postsynaptic spike is suppressed by a previous postsynaptic spike (bottom). B. Plasticity in the suppression model induced by triplets of spikes: pre-post-pre triplets induce potentiation (top left), and post-pre-post triplets induce depression (bottom right).
