ghk()

Syntax:

h.ghk(v, ci, co, charge)

Description:

Return the Goldman-Hodgkin-Katz current (normalized to unit permeability). Use the present value of celsius.

mA/cm2 = (permeability in cm/s)*h.ghk(mV, mM, mM, valence)

nernst()

Syntax:

h.nernst(ci, co, charge, sec=section)

h.nernst("ena" or "nai" or "nao", [x], sec=section)

Description:

h.nernst(ci, co, charge)

returns nernst potential. Utilizes the present value of celsius.

h.nernst("ena" or "nai" or "nao", [x])

calculates nao/nai = exp(z*ena/RTF) for the ionic variable named in the string.

Celsius, valence, and the other two ionic variables are taken from their values at the section at position x (.5 default). An error is printed if the ionic species does not exist at this location.
