Abstract :
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.
