“The master and His Emissary” is a book written by doctor and psychiatrist Iain McGilchrist (an animated summary was recently published) which examines the thoroughly divided nature of the human brain. The fact that it’s divided is easily discerned simply by taking a look at it; the two cerebral hemispheres are asymmetrical and connected only by a structure called the Corpus callosum. The theory that this might have some major impact on the way we function goes a long way back, but our understanding of it continues to evolve.
