    I am trying to create the circuit in the link attached (for some reason I couldn't attach images)

    page 3 ,figure 3, the parameters are in equ(9) and just above equ(13)

    I wrote the following code:

    *Fitzhugh Nagumo
    I1 0 1 PULSE(0 0.5mA 1NS 1NS 1NS 1NS 2ms)
    L1 0 2 30H
    R1 1 2 7500ohm
    R2 1 0 3174ohm
    C1 1 0 16.67nF
    G1 1 0 value={-0.000037037*(v(1)**3)+0.00002167*(v(1)**2)}
    .tran 0 10ms

    my problem is G1 isn't responding properly (it's giving me 0Amp) (and I think that because of that, also L1 and R1 are not working either)

    can someone please help me??
