[New modification of the technic for preserving human brain preparations]

The modification suggested is a combination of two methods--one with formalin application, another--without formalin application. At first, 5% solution of formalin is injected into the brain arterial bed, then it is injected with an artificial neoprene resine--latex. The preparation is put into a preserving liquid containing no formalin (a mixture of glycerin--45%, acetous potassium--10%, water--45%) for 1.5--2 months.
