¹Transection at 10% BL (2 weeks) → HRP at 20% BL (6 weeks; see Fig. 1A).

²Full CL at 30% BL (0 weeks) → transection at 10% BL (2 weeks) → HRP at 20% BL (6 weeks; see Fig. 1B).

³Hemi-CL on right side at 30% BL (0 weeks) → transection at 10% BL (2 weeks) → HRP at 20% BL (6 weeks, (11 right and 7 left hemi-CLs; left-right cell counts for left hemi-CL’s were reversed so that the data were normalized for hemi-CLs on the right side, see Fig. 5A).

^4/5Numbers of animals in which the cell counts on the (4) contralateral (left) side or (5) ipsilateral (right) side of the brain were greater (see Fig. 5A).

^*P ≤ 0.05 (Sign test).
