This exhibit, located near the North Entrance of the Neuroscience Building 35 on the NIH Campus, features the original illustrations of the "Grandfather of Neuroscience", famed scientist/artist Santiago Ramón y Cajal.

In addition to seven rotating original Cajal illustrations, the exhibit also features tangible 3d printed models which help offer perspective to visually impaired users.   

Santiago Ramón y Cajal (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 17 October 1934) was a Spanish neuroscientist and pathologist, specializing in neuroanatomy, particularly the histology of the central nervous system. He and Camillo Golgi received the Nobel Prize in Physiology or Medicine in 1906,[1] with Ramón y Cajal thereby becoming the first person of Spanish origin who won a scientific Nobel Prize. His original investigations of the microscopic structure of the brain made him a pioneer of modern neuroscience. Hundreds of his drawings illustrating the delicate arborizations of brain cells are still in use for educational and training purposes.
