aeif_cond_exp - Conductance based exponential integrate-and-fire neuronDescription:
model according to Brette and Gerstner (2005).
aeif_cond_exp is the adaptive exponential integrate and fire neuron
according to Brette and Gerstner (2005), with post-synaptic
conductances in the form of truncated exponentials.
This implementation uses the embedded 4th order Runge-Kutta-Fehlberg
solver with adaptive stepsize to integrate the differential equation.
The membrane potential is given by the following differential equation:
C dV/dt= -g_L(V-E_L)+g_L*Delta_T*exp((V-V_T)/Delta_T)-g_e(t)(V-E_e)
tau_w * dw/dt= a(V-E_L) -W
Note that the spike detection threshold V_peak is automatically set to
V_th+10 mV to avoid numerical instabilites that may result from
setting V_peak too high.
