Figure 2. Nonparetic forelimb training worsens performance of the paretic forelimb in rats without corpus callosum transections.

Figure 2

A. Performance during the period of training of the nonparetic, ipsilesional, limb (NonParT) after unilateral SMC lesions in rats with or without callosal transections (CCX). There was no significant difference in acquisition of the skilled reaching task with the nonparetic forelimb between these two groups. The first day of nonparetic limb training was 6 days after lesions. B. After training the nonparetic limb, NonParT rats had major deficits in the paretic, contralesional forelimb compared to control animals. C. In contrast, in rats with unilateral SMC lesions and callosum transections performance with the paretic forelimb was not significantly affected by prior nonparetic forelimb training. Day 1 of the paretic limb training period in B and C corresponds to 22 days after the lesions. Data in panels B and C were calculated as %[(pre-operative- postoperative)/preoperative] successful retrievals per reach attempt. Data in all figures are means ± SEM. * p < .05.
