FIG. 11.

Transverse sections of the spinal cord at midthoracic levels immunostained for protein kinase C-gamma to visualize the dorsal component of the corticospinal tract (dCST). The dCST on the right side of the spinal cord is decreased in size after a 60-psi blast. Because the axons of pyramidal cortical neurons cross the midline at the spinomedullary junction before descending in the CST, these results are consistent with left pyramidal tract injury by blast to the left side of the cranium. Images A and B are at the same magnification. Color image is available online at www.liebertpub.com/neu
