Comparison of the faults made by each limb separately during the execution of Grid Test seven days after pedunculopontine nucleus lesion. (A) Faults made by the contralateral forelimb (H(2,38) = 10.91 p < 0.01). (B) Faults corresponding to contralateral hind limb (H(2,38) = 6.71 p < 0.05). (C) Faults made by the ipsilateral forelimb (H(2, 38) = 3.81 p > 0.05) (D) Faults corresponding to ipsilateral hind limb (H(2, 38) = 8.45 p < 0.05). Kruskal–Wallis test. * p < 0.05, ** p < 0.01. The points represent the number of errors of each experimental subject. The horizontal lines represent the medians of each sample.
