Figure 1

Example demonstrating the enhancement in synchronization of mutually coupled interneurons through spike timing dependent plasticity on inhibitory synapses. (a) Schematic diagram of reciprocally connected interneurons with self-inhibition. (b) The ratio of average firing period of the two neurons is plotted as function of heterogeneity in intrinsic firing frequency of each neuron. The ratio (diamond) represents a dynamic synapse, where STDP modulates the synaptic strength between the coupled neurons. The ratio in (star) represents the situation when the synaptic strength is static. (c) The synchronization index κ is plotted as function of heterogeneity H for the two cases discussed in (b).
