Change excitability of Morris-Lecar model via physiological bifurcation control

To understand how neuron encodes the stimulus input into firing patterns is significant in neuroscience. The different firing patterns are resulting from different bifurcations from the dynamical viewpoint. Here we design a bifurcation control from a physiological view by employing the wash-out filter. Then Morris-Lecar model is selected to verify the proposed method. We finally derive the physiological basis of wash-out filter control is affecting the result of competition between currents with different dynamics in the sub-threshold potential.
