<meta:notes>A network of cells connected in NeuroML Level 3. Extra tags are included to give an
idea how the standard can be extended. Note most NeuroML compliant applications will ignore this extra
data, but will still be able to extract the essential physiological information.
Note: this is a CUSTOM EXTENSION. The parsing application which generates the NMODL
file for NEURON should replace the standard Ohmic current at a gap junction:
i = weight * g * (v - vgap)
with the voltage dependent one below. The file remains valid NeuroML. Only
simulators which support this custom extension will model the synpase correctly.
Note: not a physiological voltage dependence.
