Uncovering Modes

A video of the unreduced tongue model, stimulated with muscle activations. It requires 3 equations per node.

By applying stimulation to our model of the tongue, we can analyze the output from the simulations to uncover the primary 'modes' of movement available.  Using these modes, reducing the model to something with fewer degrees of freedom is possible.

Reducing the Tongue

The reduced model stimulated with the same muscle activations. It requires only 5 equations.

Despite greatly reducing the degrees of freedom in our reduced model of the tongue, the response to stimulus is approximately the same as in the unreduced model.  This has important ramifications for the feasability of some large or complex model simulations.
