In the late 1600’s, medical researchers, Willis (British) and Descartes (French), independently published papers declaring different areas of the brain controlled specific bodily functions. Interestingly, Willis engaged one of his medical mates, Chris Wren, to draw the diagrams for his book. Wren gave up medicine and took up architecture and designed a few Cathedrals, Abbeys and Hospitals, including St Paul’s Cathedral, and was knighted as Sir Christopher Wren.
