Fig. 8From: Optimization of ultrastructural preservation of human brain for transmission electron microscopy after long post-mortem intervalsAnalysis of the density of myelinated axons in human frontal lobe with different PMI’s prepared with standard embedding and cryo-substitution cocktail I. Mean and standard deviation values of the number of myelinated axons per square micrometer image are shown. One-way ANOVA with Scheffé post-hoc analysis revealed a significant difference *(p < 0.05) between the standard embedding and cryo-substitution cocktail IBack to article page
