Modulation of striatal single units by expected reward:
a spiny neuron model displaying dopamine-induced bistability.

The paper doesn't state the reversal potential for this current.
However, the figures are reproduced if e_leak equals e_k.
RANGE g, i, iL
(mA) = (milliamp)
(uA) = (microamp)
(mV) = (millivolt)
(mS) = (millimho)
g = 0.008 (mS/cm2) <0,1e9>
e = -90 (mV) : same as e_k in their model
iL (uA/cm2) : for consistency with their usage of uA/cm2
iL = g*(v - e)
i = (0.001)*iL
