split brain

ID_BS_CRISP_MASTE_AP_001

Back in junior high school health class, we were told that the brain has two different hemispheres — the left and the right. The left brain, the textbook stated, is responsible for language, math, and science, logic and rationality. The right brain was the artistic one, the creative half of the brain. But that’s not quite true. Neuroimaging and experiments on patients with split brains and brain damage to only one hemisphere have allowed a much more detailed, and fascinating, accounting of how the two parts interact with the world, and how they combine to become a unified consciousness (and, in some cases of mental disorders, how they occasionally don’t). Iain McGilchrist has combined scientific research with cultural history in his new book The Master and His Emissary: The Divided Brain and the Making of the Western World to examine how the evolution of the brain influenced our society, and how the current make up of the brain shapes art, politics, and science, as well as the rise of mental illness in our time — in particular schizophrenia, anorexia, and autism.
