Hodgkin-Huxley review

 * $$C_m, G_L, V_L$$ are constants
 * $$C_m \approx 1\mu F/cm^2$$
 * $$V_K \approx 60 mV log\frac{c_K^o}{c_K^i}$$
 * $$V_{Na} \approx 60 mV log\frac{c_{Na}^o}{c_{Na}^i}$$
 * $$G_K=\overline{G_K}n^4, G_{Na}=\overline{G_{Na}}m^3h$$
 * m, n, h obey $$x+\tau_x(V_m)\frac{dx}{dt}=x_\infty(V_m)$$
 * $$\tau_m \ll \tau_h, \tau_n$$
 * As $$V_m\uparrow$$
 * $$h\infty\downarrow$$
 * $$n\infty,m\infty\uparrow$$
