ghk()¶ ↑ - Syntax:
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)*ghk(mV, mM, mM, valence)
-
nernst()¶ ↑ - Syntax:
nernst(ci, co, charge)nernst("ena" or "nai" or "nao", [x])
Description:
nernst(ci, co, charge)- returns nernst potential. Utilizes the present value of celsius.
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 currently accessed section at position x (.5 default). A hoc error is printed if the ionic species does not exist at this location.
