(a) There were no significant differences between groups in the speed of response to near holes on either side. (b) Movement times to execute a correct response to the far holes were lengthened significantly on both sides in the lesion group (∗∗, P < 0.01), although the effect was greater on the contralateral side. The graft animals were recovered significantly from lesion levels on the contralateral (††, P < 0.01), but not the ipsilateral, side (see text).
