Table IV.

Parameters of the current-distance relationship estimated using the refractory interaction technique with threshold stimulation intensity. The left column includes estimates made using data from all interelectrode distances, while the right column includes estimates made using data from only 200 and 300 µm interelectrode distances. The rows are individual estimates and mean ± s.d. from three different random fiber distributions.
