A 19th century human brain plastinated for medical study and a teaching aid. Plastination is a technique or process used in anatomy to preserve bodies or body parts, first developed by Gunther von Hagens in 1977. The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay. Displayed in a glass dome resting on a carved wooden plinth. Ex. Billy Jamieson Collection.
