.. py:class:: IzhIF
Izhikevich neuron (integrate and fire).d Vm /dt = a0 * Vm^2 + b0 * Vm + c0 - u + I/Cm d u / dt = a * ( b * Vm - u ) at each spike, u -> u + d by default, a0 = 0.04e6/V/s, b0 = 5e3/s, c0 = 140 V/s are set to SI units, so use SI consistently, or change a0, b0, c0 also if you wish to use other units. Rm, Em from Compartment are not used here, vReset is same as c in the usual formalism. At rest, u0 = b V0, and V0 = ( -(-b0-b) +/- sqrt((b0-b)^2 - 4*a0*c0)) / (2*a0) equivalently, to obtain resting Em, set b = (a0*Em^2 + b0*Em + c0)/Em
