Changing Your Mind

Tales from Both Sides of the Brain: A Life in Neuroscience - Michael S. Gazzaniga The Brain's Way of Healing: Remarkable Discoveries and Recoveries from the Frontiers of Neuroplasticity - Norman Doidge

“I’m of two minds,” we say. Or, “I changed my mind.” These phrases roll casually off the tongue, but we don’t mean them literally. Maybe we should, according to two new books that explore the fascinating history and tantalizing future of neuroscience.


Are you primarily right-brained or left-brained? You might think you know, but Michael S. Gazzaniga is here to tell you it’s not that simple. Gazzaniga pioneered split-brain research with his colleagues at the California Institute of Technology in the 1960s. In Tales from Both Sides of the Brain: A Life in Neuroscience, he details the experiments that led us to talk about the brain’s two hemispheres in the first place. Filled with scientific luminaries like psychobiologist Roger W. Sperry and theoretical physicist Richard Feynman, Tales from Both Sides of the Brain takes us back to the intellectually energetic laboratories of Caltech. In scenes that read like episodes of “The Big Bang Theory”—intellectual energy abounds—we sit in on experiments done with split-brain patients, whose brains’ hemispheres had been surgically separated to treat epilepsy.
