Several RKYHS bioengineering students 3D printed a full-size skull of Phineas Gage, a railroad worker during the 1800s who was famous for his unlikely survival of an accident where an iron rod was shot through his skull and frontal lobe. The AP Psychology class is currently learning about Phineas Gage, and how changes in his behavior after the accident led to an initial understanding of the function of this part of the brain. The bioengineering students, who are beginning work on their capstone project to develop a “3D Bio-Printer” (a 3D printer that can print with living cells to print functional tissue) needed to begin their investigation of the inner workings of conventional 3D printing. The students printed the skull of Phineas Gage, together with a removable rod that pierces the skull, to help demonstrate to the AP Psychology class the anatomical path of the injury and its trajectory through Gage’s frontal lobe in his 19th century accidental frontal lobotomy.
