That's the analogy offered by Alan Cohen, professor of neurosurgery at the Johns Hopkins School of Medicine. But using cadavers for this purpose has its limitations, namely the expense and an imprecise imitation of brain surgery itself. So Cohen and his team tapped 3D printing technology and some Hollywood special effects experts to craft a lifelike head for better surgery simulation, complete with the texture of the skull and brain tissue.
