Semi-thin sections of human brain samples. All samples were prepared with cryo-substitution cocktail I, and after cutting ultra-thin slices 500 nm thick semi-thin slices were dyed with toluidine blue. The arrows indicate vessels with a light halo and the arrowheads glia cells with halo. a Case 1, PMI 16 h, frontal grey matter, zoom in is indicated with black square and shown in (b), c Case 2, PMI 18 h, frontal withe matter, d Case 3, PMI 20 h, frontal white matter, e Case 4, PMI 24 h, frontal withe matter. Scale bars = 20 μm
