Morphology

diameter = 1um length = 300um Cm = 1*uF/cm*2 Ri = 150ohm*cm N = 200 morpho = Cylinder(diameter=diameter, length=length, n=N)

Passive channels

gL = 1e-4*siemens/cm2 EL = -70mV eqs = ''' Im = gL (EL - v) : amp/meter2 I : amp (point current) '''

neuron = SpatialNeuron(morphology=morpho, model=eqs, Cm=Cm, Ri=Ri, method='exponential_euler') neuron.v = EL la = Ri * Cm**(0.5)

print("Electrotonic length: %s" % la)

neuron.I[0] = 0.02nA # injecting at the left end run(100ms, report='text')
