A new plastination technique for head slices containing brain.

The results of plastination of head slices are unsatisfactory when muscles, connective tissue and the brain are impregnated with one and the same resin. The epoxy- or polyester-plastination technique renders transparent either the head without the brain (e.g. E 12) or the brain without the adjacent tissues (e.g. P 40). A new technique is described which allows a homogenous transparency of both the head and the brain.
