Summary:
Activity-dependent manner of changes in synaptic efficacy, namely, short-term plasticity (STP), is observed in several areas of cortical or hippocampal neurons. A canonical phenomenological STP model well mimics both kinetics of depression and facilitation synapses. The canonical model, however, cannot realize supralinear facilitation in excitatory synapses on inhibitory low-threshold spiking neurons. Some biophysically detailed models account for the facilitation growth of the synapses but the models too much cost in large-scale neural network simulations. In this study, we propose a model as simple as the canonical phenomenological model by introducing nonlinearity.
