1. A method comprising:
- defining, using at least one processor, an electrical field solution within a preselected medium, the electrical field solution defined based on a configuration of at least one electrode;
generating a first grid of neuron representatives in association with the at least one electrode;
determining, using the at least one processor, an activation threshold value for each of the neuron representatives within the first grid of neuron representatives based on the electrical field solution;
based on the activation threshold values for pairs of adjacent neuron representatives, adding additional neuron representatives between at least some of the pairs of adjacent neuron representatives; and
generating a second grid of neuron representatives comprising the first grid of representatives, and the additional neuron representatives.

Abstract
A visualization of an area or volume of tissue activated during stimulation according to a set of stimulation parameters is generated. The area or volume of activation is modeled based on a non-uniform grid of model neurons. Select portions of the grid have the model neurons more closely spaced, resulting in finer resolution graphical representation, while less closely spaced model neurons in other portions of the grid may avoid additional computation time.
