FIG. 5.

Unaffected forelimb-evoked sensory-evoked potentials in contralesional cortex are reduced in peak latency. (A) Stylized figure showing the position of the two electrode designs used in the experiments (labels 1 and 2) in the contralesional right (R) cortex relative to the position of the left (L) hemisphere primary injury site (circular, dashed line). (B) Group-averaged sensory evoked potential signal from rats pre-injury (solid line), at 1 week (light gray line) and at 4 weeks post-injury (bolded, dotted line). (C) Plot of peak latencies for a single stimulus and response quantified at different times post-injury and showing a significant reduction. *p < 0.05, ***p < 0.001). (D) Plot of peak amplitudes for a single stimulus showing no significant response at any time-point post-injury.
