Equations of the NL neuron model

Variable Equation
Compartment c = soma or node
Membrane potential
Na current INac = ḡNac · mc hc · (ENaVc)
KHVA current IKHVAc = ḡKHVAc · nc · (EKVc)
KLVA current IKLVAc = ḡKLVAc · dc · (EKVc)
Leak current Ileakc = gleakc · (EleakVc)
Synaptic input Isynapticc = gsynapticc · (EsynapticVc)
Axonal current Iaxonsoma = gaxon · (VnodeVsoma), Iaxonnode = −Iaxonsoma
Channel variable (x = m, h, n, d) dxc/dt = φ{αx(Vc) · (1 − xc) − βx(Vc) · xc}
Temperature dependence φ = Q10(T−23.0)/10(Q10 = 2.5, T = 40°C)
Na channel activation αm(V) = 3.6exp((V + 34)/7.5), βm(V) = 3.6exp(−(V + 34)/10.0)
Na channel inactivation αh(V) = 0.6exp(−(V + 57)/18.0), βh(V) = 0.6exp((V + 57)/13.5)
KHVA channel activation αn(V) = 0.11exp((V + 19)/9.1), βn(V) = 0.103exp(−(V + 19)/20)
KLVA channel activation αd(V) = 0.2exp((V + 60)/21.8), βd(V) = 0.17exp(−(V + 60)/14)
• This table summarizes the equations used in our simulation. In the single-compartment model, Iaxonnode = Iaxonsoma = 0 and only the somatic compartment was considered.
