Detailed Description

The NMDAChan incorporates calculations for Mg block, Nernst potential and/or GHK estimates for the fraction of current carried by Ca. These can also be done by messaging but it is messy and slow, so I've lumped them. Also I've assumed that we're only dealing with the GHK equation for Ca. This is not so good considering that other ions also go through the channel.

void NMDAChan::vProcess	(	const Eref &	e,
		ProcPtr	info
	)			[virtual]

Note the implicit mapping between permeability and conductance. From the GENESIS source code: A thought about the units, by EDS 6/95 (based on Hille 92): Units: p in M/s EF/RT and z are dimensionless F in C/mol Cin and Cout in mM==mol/m^3 Then Ik is really in units of C/s/m^2==A/m^2, so we compute a current density. As we replace in practice p by Gbar, which has already been scaled for surface, we get rid of the density factor.
