A comparison: 3D-nerve vs. extruded nerve model

(A) Model computation information, with averaged values across three individual electrode positions for each subject. Computational times for the calculation of fiber recruitments were averaged across 1000 fibers.

(B) Comparative representation of fascicles for the 3D-nerve and the extruded model (the former based on the three nerve level segmentations, the latter constructed by a simple extrusion from the middle cross-section) with a magnification of an exemplary fascicle for both subjects.

(C) Visual representations of deviations of relative recruitments across 6 individual active site stimulations in one of the models.

(D) On the left: the 3D-nerve and the extruded version of the nerve model of Subject 2 as an example, with 3 highlighted fascicles chosen for the electrode structure placements and the comparisons. On the right: boxplot of the mean absolute deviation (MAD) of relative recruitment at seven different cross-sectional levels (corresponding to the electrode position levels) averaged for both subjects.
