On 3/31/2005 a NEURON user asked:
How can I control the extracellular environment?

If your model has no ion accumulation mechanisms (diffusion,
buffers, transport mechanisms), ionic equilibrium potentials
are treated as constants and are specified with simple
assignment statements. When there is an ion accumulation
mechanism, the affected ionic species becomes a state variable
in the sections where it accumulates, and you will need to read
the portions of chapters 8 and 9 of the NEURON book that are
relevant to ion accumulation.
