BFF topography

A, B: Upper part of the figure shows two examples of BFF distributions along the spinal cord in two different animals. Heat maps show that BFFs with anteroventrally directed vectors were mostly represented in the rostral part of the spinal cord, while BFFs with posterodorsal orientation tended to be represented in the caudal part of the spinal cord. Lower part of the figure shows topography of the BFF clusters. C, D: BFF cluster distributions on the spinal cord of one animal (C) and all animals (D) are shown. BFF clusters were likewise topographically represented on the spinal cord, with clusters showing anteroventral (cluster 1) and posterodorsal (cluster 3) orientation mostly represented in the rostral and caudal parts, respectively. In C, which shows the results from the same mouse in B (mouse 11), two BFFs (BFF3 and BFF4) were grouped into the same cluster (cluster 2), and both BFF3 and BFF4 in this mouse and cluster 2 were represented in the caudal part of the spinal cord.
