Error in calculation error of the value of $I_m$ where lower Hopf bifurcation occurs. Error in calculation of the value of $I_m$ at which the lower Hopf bifurcation occurs using the midpoint rule (red stars) and the Gaussian quadrature (blue circles). The error for the midpoint rule appears to decay as $1/N$. Other parameters: $g_{\mathrm{syn}}=0.3$, $I_s=7.5$.
