Zernov's Encephalometer

The first prototype of a stereotaxic instrument was conceived and designed in 1889 by Dmitrii Zernov (1843-1917) - a professor of anatomy at Moscow University. His invention was based upon the similarity of the shape of cranium and brain to the terrestrial globe. This resulted in a real geographical atlas of the human brain, where each cerebral structure was expressed in the degrees of longitude and latitude. Zernov wrote: "I built an instrument which enables to project the pattern of cranial sutures or cerebral sulci or deep-seated brain structures on the spherical surface and then transform it onto the plane similar to the projection of the terrestrial globe on the map. The localisation of a given point on the brain surface is determined by the degrees of latitude and longitude."
