Units and dimensions¶
Support for dimensional quantities is a fundamental (and essential) feature of NeuroML, backed up by support for units and dimensions in LEMS.
The basic rules are:
specify the dimensions of quantities in LEMS
use compatible units defined in the NeuroML schema in NeuroML models.
The main motivation for this is that fundamental expressions for defining a model are independent of any particular units. For example, Ohm’s law, V = I * R relates to quantities with dimensions voltage, current and resistance, not millivolts, picoamps, ohms, etc.
Users can therefore use a wide range of commonly used units for each dimension defined in the standard unit and dimension definitions of NeuroML 2 without worrying about conversion factors.
Additionally, please keep in mind that:
