FIG. 2.

(Left) Darkfield digital micrographs of transverse hemisections through the lumbar spinal cords of a sham animal (top), an injured animal treated with vehicle (spinal cord injury [SCI]+vehicle, middle), and an arachidonyl trifluoromethyl ketone (ATK)-treated injured animal (SCI+ATK, bottom), after injection of horseradish peroxidase conjugated to the cholera toxin B subunit (BHRP) into the left vastus lateralis muscle. (Right) Computer-generated composites of BHRP-labeled somata and processes drawn at 480-μm intervals through the entire rostrocaudal extent of the quadriceps motor pool; these composites were selected because they are representative of their respective group average dendritic lengths. Scale bar, 250 μm. Color image is available online.
