This model of the brain was formed from a real human brain. Special materials and an elaborate manufacturing process allow for a previously unknown level of detail in recreating structures in anatomy lessons. The left and right hemispheres are separate and allow you to see the brain's rod (corpus callosum) and the rim, as well as the hypothalamus, bridge, and cerebellum. There are two different models available, each one fits a specific skull. The skull is not included.
