Fig. 7From: Managing heterogeneity in the study of neural oscillator dynamicsThe phase plane for a single uncoupled neuron. h-nullcline (dashed, on which dh/dt=0) and the V-nullclines (circles, on which dV/dt=0) for I m =10,15and35 (top to bottom). Also shown (solid) is the stable periodic orbit that exists when I m =15.Back to article page
