Each of the brain’s 100 billion neurons has somewhere in the realm of 7,000 connections to other neurons, creating a tangled roadmap of about 700 trillion possible turns. But thinking of the brain as roads makes it sound very fixed—you know, pavement, and rebar, and steel girders and all. But the opposite is true: at work in our brains are never-sleeping teams of Fraggles and Doozers who rip apart the roads, build new ones, and are constantly at work retooling the brain’s intersections. This study of Fraggles and Doozers is the booming field of neuroplasticity: how the basic architecture of the brain changes over time. Scientist, neuro math geek, Science Channel personality and accomplished author Garth Sundem writes for ScriptPhD.com about the phenomenon of brain training and memory.
