Neuronal adaptation by varying transmission delay on recurrent excitation

A neuronal model with recurrent excitation (positive feedback of its own output) and transmission delay is presented. The neuron has two additional biologically plausible attributes: a time varying threshold and a decaying soma potential. The authors study the effect of the feedback delay in such a neuronal model. The simulation results show that the feedback delay contributes to the neuronal adaptation in making new associations or breaking previous ones.
