Bar chart of the mean densities of immunopositive axons displaying caspase-linked SBDP-120- immunoreactivity in the CSpT (black) and the MLF (gray) at various postinjury survival times after impact acceleration injury. Bar chart of the mean densities of immunopositive axons displaying caspase-linked SBDP-120- immunoreactivity in the CSpT (black) and the MLF (gray) at various postinjury survival times after impact acceleration injury. Error bars indicate SEM, and the asterisks indicate statistical significance (p < 0.05) between consecutive survival times. (Significant changes between non-neighboring survival times are not indicated.) András Büki et al. J. Neurosci. 2000;20:2825-2834 ©2000 by Society for Neuroscience
