It has long been known that cognitive (thinking and reasoning) stimulation of the brain's cerebral cortex enhances the brain development of children and reduces degeneration with aging. In addition, competition enhances engagement. During long trips or while waiting, Heilman, a neurologist, along with his grandchildren, children, and son-in-law would play games. Studies of patients with brain injuries and functional brain imaging have revealed that different parts of the cerebral cortex perform different functions. We developed and selected games that we had fun playing, were competitive, did not need a computer or purchases, and stimulate different specific areas of the brain. In this book, we describe areas of the cerebral cortex and their functions. We then describe some games that may stimulate these areas, as well as provide enjoyment.
