title: Neuron simulations with SABER.
abstract: Computational models can provide critical tests of hypotheses of neuronal function. These models are essential for dealing with the complications of time- and voltage-dependent (active) ionic conductances. Commercial circuit analysis programs have been useful tools for this work. We report our experience modelling biophysically realistic membrane properties with SABER (Analogy, Inc.), a new general purpose simulator. SABER allows construction of models with arbitrary membrane properties. This is a major advantage over similar programs (e.g. SPICE), which are limited to a predefined library of electronic components. The empirically determined equations that describe rate constants, ionic conductances, currents, and concentration shifts can be translated directly into model elements ('templates') written in C-like code. We describe the development of SABER models that simulate a synapse and an action potential.
