In The Other Brain, R. Douglas Fields turns the spotlight on glia—a group of cells that comprise about 90% of all brain cells. Less well-known than neurons—and once relegated to the role of "helper" to the neuron's dominance—glia come into their own in Fields's work. He draws attention to new research on the critical role of glia in a host of brain functions and failures—from information processing to multiple sclerosis, stroke, and migraines. An enjoyable and informative read, The Other Brain fills an important gap in the understanding of how the brain works.
