(a) Traces of the membrane potential (dashed lines) and autaptic current (solid lines).[ 43 ] (b) The phase portrait corresponds to panel (a). Panels (c) and (d) are the enlarged plots of panels (a) and (b), respectively. The different colors indicate different integral initial conditions (The specific set of parameters can be found in Ref. [ 43 ]). The inset in panels (a): The membrane potential of HH neuron–autapse system perturbed by a brief step pause (black solid line).
