Does NEURON automatically update Equilibrium potential?

Post by gabrielleg »

If I'm writing a mechanism for internal calcium accumulation that is similar to Example 9.6 for Extracellular Potassium Accumulation (in the NEURON Book), can I explicitly calculate a new equilibrium potential for calcium (eca) in that mechanism, or does NEURON update eca automatically without my having to write any code?

Good question.

If a section contains a mechanism that WRITEs an ionic concentration, NEURON will
automatically recompute the corresponding equilibrium potential on every fadvance().
For a more thorough discussion of this and other issues related to equilibrium potentials
and concentrations, see the documentation of ion_style() in the Programmer's Reference
