Figure 1

Location and extent of unilateral cervical lesion in Mks 1–3. Location and extent of the unilateral lesion (grey area), performed at C7/C8 level in Mk1, Mk2 and Mk3, shown on a reconstructed frontal view of cervical cord (three rightmost panels). The inset on the left is a frontal section of the macaque monkey cervical cord showing the distribution of CS axons (black dots) as a result of injection of the anterograde tracer Biotinylated Dextran Amine (BDA) in the right motor cortex (as recently reported in [41]). The CS axons originating from the right hemisphere are distributed mainly in the left dorsolateral funiculus (90–95%), representing the decussated CS tract. The uncrossed CS tract (5–10%) comprises, on the right side, axons in the dorsolateral funiculus and in the ventral funiculus. Scale bars = 2 mm.
