2D PCA projection of evoked fiber responses across subjects and stimulation locations. Each marker represents the 2D PCA projection of a 15-dimensions evoked fiber activations vector ((A\(\beta\), A\(\gamma\), B) \(\times\) (0.1, 0.25, 0.5, 1.0, 2.0)mA, pulse width 260\(\,\upmu\)s) from a given stimulation location. Markers are color-coded by subject. Radial stimulation pairs are indicated with triangles. Bar plots on the right-hand side show the reverse projections of different points sampled from the two-dimensional space (labelled as z)
