Microscopic distribution of CSF tracer in spinal cord white and gray matter 1 week post-surgery. Graphs illustrate mean fluorescence intensity measured microscopically in each spinal segment in the white matter (a, c) and gray matter (b, d) from control (n = 4 per group) and extradural constriction (n = 6 per group) animals, 10 min (a, b) and 20 min (c, d) after cisterna magna injection of CSF tracer (OA-647). Results are shown as mean fluorescence ± SEM, given as arbitrary units (AU). Statistical significance was determined using two-way ANOVA, with Bonferroni’s multiple comparison test. No statistical differences were observed in post hoc analysis. WM: white matter; GM: gray matter
