The Yale Center for Engineering Innovation and Design has produced a model of a lone neuron (pictured) using its 3D printers. “We see a future in which 3D models of nerve cells will be an integral part of doing research and of teaching neurobiology,” said Gordon Shepherd, professor of neurobiology at the Yale School of Medicine.
