Appendix 1—figure 2. Illustration of models for an inversely adapting enhanced-excitability LIF (ELIF) neuron, and for short-term synaptic plasticity.

(A) Sample spike train. (B) The resulting evolution of firing threshold for an inversely adapting neuron (ELIF neuron). (C, D) The resulting evolution of the amplitude of postsynaptic potentials (PSPs) for spikes of the presynaptic neuron for the case of a depression-dominant (STP-D: D >> F) and a facilitation-dominant (STP-F: F >> D) short-term synaptic plasticity.
