I need help solving this in MATLAB:

5.2 FitzHugh-Nagumo Model of Neuron When electric current stimulate a neuron, the membrane potential gener- ates a spike or train of spikes. A simple mathematical model for such an excitable media or relaxation oscillation is given by the FitzHugh-Nagumo model[10]: 5.57a) (5.57b) where v is the membrane potential, w a recovery variable which activate the outgoing current. I is the incoming current which controls the dynamics. Typical parameter values are a-0.08, b above which the neuron is excited (the membrane potential periodically oscillates). 0.7, c = 0.8. Find critical 1 5.2 FitzHugh-Nagumo Model of Neuron When electric current stimulate a neuron, the membrane potential gener- ates a spike or train of spikes.
