(a) Several fiber tracts produced by geometrical optics ray tracing of the Fokker-Plank equation using the ESP equilibrium probability distribution shown in Figure 2. (b) Blow up of one of the tracts showing an interesting property of the ray tracing: the tracts reaching the fiber ends can get reflected at the boundary and form a closed cycle repeating itself again and again. (c) All fiber tracts obtained using seeds (d) selected with single threshold from the ESP equilibrium probability distribution. The processing of 512 total seed produced 372 fiber tracts with only two (one red and one green) incorrectly finished at the neighboring ending point. These results correspond to slightly more than 0.5% false positive rate.
