The human brain has long been a mystery, but twenty-first century science is beginning to reveal some of its inner workings. With microscopes and brain scans, with psychological experiments and breakthroughs in genetics, neuroscientists are developing new theories about every aspect of our minds—from the nature of consciousness to the causes of disorders like autism and schizophrenia. In Brain Cuttings, award-winning science writer Carl Zimmer takes readers on fascinating explorations of the frontiers of research, shedding light on our innermost existence—the speed of thought, our perception of time, the complex flashes of electricity that give rise to fear and love, and more.
