and Faraday's constant in NEURON. Specifically, NEURON uses what
appear to be incorrect values:
Code: Select all
--------------------------------
R Faraday
-------------------------------------------
correct 8.3144598(48) 96485.33289(59)
neuron 8.3134 96485.309
-------------------------------------------

Is there a reason why these specific values have been used?
The reversal potentials that NEURON calculates using the Nernst
equation have errors as a result in the 4th digit, for example
the potassium and sodium species using the default concentrations
and temperature:
Code: Select all
--------------------------------------
ek ena
----------------------------------------------
nernst -74.17164678271602 63.55148117386006
NEURON -74.162211 63.543396
----------------------------------------------
to the point where it probably doesn't have a significant impact
on people's models, but it makes validation a challenge!
