FIG. 7.

Motor neuron sparing. Motor neuron sparing was estimated by counting the total number of neurons per section with a diameter greater than 25 micrometers. Quantification of cresyl violet stained sections within the hemicord ipsilateral to injury (A) Rostrocaudal extent of spared motoneurons over the range of 4.32 mm rostral and caudal to the lesion epicenter (Mean±standard error of the mean). (B) Bar graphs of the average number of motoneurons within 2.16 mm of the injury epicenter for each group of animals (mean+standard error of the mean, * denotes p<0.005; intact n=4; sham n=4; 0.6 mm n=5; 0.8 mm n=6).
