FIG. 9.

Histology. Example shows the lesion epicenter from a trained and non-trained male rat with spinal cord injury. A bilateral rim of tissue sparing with staining of both Luxol fast blue and cresyl violet (Kluver-Barrera method) can be seen. Total percent white matter sparing measured (relative to rostral/caudal intact sections from the same animal, not shown) and Basso-Beattie-Bresnahan (BBB) scores assessed during the final week of testing for the animals shown was 19.9%/BBB=16 (trained) and 18.7%/BBB=12 (non-trained).
