Fig. 3 a 7 T MRI of a post‑mortem fixated brain. T2 TSE axial image, 2.0 mm thickness and 0.2 mm in plane resolution. b 7 T MRI of a post‑mortem fixated brain. 3D GRE TR 12 s, TE 8 s, 0.3 mm in plane resolution and 0.6 mm slice thickness. Black arrows in b and c point to a small liquifying infarct in the posterior region of the left thalamus. c Celloidin section of the same brain as depicted in a and b . 420 μm section thickness and gallocyanin staining. d Higher magnification of the region with small liquified infarct at the border of the posterior ventrocaudal nucleus and the pulvinar thalami. The shape and the size of the infarct region are similar after 7 T imaging and after celloidin embedding of the brain that was cut into 283 horizontal sections. The scalebar in c 5 mm long and in d it is 1 mm width. c and d show C caudate nucleus, Ca crus anterius, Cp = = = = = crus posterius of the internal capsule,
