Stability and Competition in Multi-spike Models of Spike-Timing Dependent Plasticity
Fig 2
A. Schematic illustration of spike interactions in the triplet model in which previous presynaptic spikes induce extra depression (top) and previous postsynaptic spikes induce extra potentiation (bottom). B. Plasticity due to triplets of spikes: pre-post-pre triplets induce depression or weak potentiation (top left), and post-pre-post ordering induces mostly potentiation (bottom right). This figure is based on parameters fit to hippocampal data (Table 2).
