Fig. 3From: Optimization of ultrastructural preservation of human brain for transmission electron microscopy after long post-mortem intervalsQuantification of the quality of the preserved myelin sheaths with different substitution cocktails compared to standard embedding. Analysis of the quality of the myelin sheath preservation, well-preserved myelin sheaths in blue squares, disbanded myelin sheaths are cyan dots, and unspecified myelin sheaths are shown in green triangles.
