Figure 1From: Neural oscillations arising from a linear current with negative conductanceA. Addition of I NL to a biological PD neuron in TTX results in oscillatory activity, an effect mimicked by a 2d model containing I NL and I K . (Ctrl: -50 mV.) B. The 2d model bifurcation diagram with g NL as parameter shows a limited range of oscillatory activity bound by two Hopf bifurcation points.Back to article page
