This image comes from Marc Steinmetz’s photoessay about plastination, the tissue preservation technique invented by the controversial German anatomist Gunther von Hagens.
Plastination involves replacing the water and fats in the tissues with silicon or some other polymer. The specimen is first fixed in alcohol, then dehydrated, impregnated with the polymer and finally allowed to harden.
In the photograph above, the coronal brain sections have been placed under ultraviolet light for curing. The black stains visible in the slices show the sites of a massive haemorrhage which killed this individual.
