Fig. 3.

Consistently observed features of hand maps in the CN (A–F) and area 3b (G, H). Note that (1) normally in both the CN (E) and area 3b (G), the glabrous representation (gray) is continuous and large, whereas the dorsal representation (striped) occupies adjacent, discontinuous, small patches, and (2) after injury, the dorsal representation in the CN (striped) enlarged and became continuous across central CN locations normally representing glabrous inputs (A–D and F vsE), whereas the dorsal representation in area 3b also enlarged into area 3b locations normally representing glabrous inputs, but remained discontinuous and patchy (striped;H vs G) (see Fig. 7 for further examples). For CN maps, dorsal = up and medial =right. Scale bar, 1 mm. For area 3b maps, anterior = up and medial = right. Scale bar, 1 mm.
