Firing rates, synaptic efficacy and cross-correlation change during the adaptation. A The time course of firing rates and the averaged synaptic efficacy of the network during the adaptation. \( \left\langle {\text{ux}} \right\rangle \) is temporally enhanced during the adaptation due to the STF, but in the long term, strong STD drives the synaptic efficacy to background level. Stimulation is during 0–1500 ms. B The enhancement of cross-correlation between neurons during the adaptation
