In this thorough health and science overview, journalist Horstman (Overcoming Arthritis) reviews a full day of brainwork by accounting for the mental processes of everyday activities, arranged by hour, beginning with 5 a.m. and “coming to consciousness.” Fascinatingly, Horstman shows how, as hormone and neurotransmitter levels change throughout the day, there may be an optimal time for everything. Moving through the workday, Horstman discusses stress, decision-making, hunger and fatigue, ADHD and more, before returning home to cover music, humor, sex, fear and sleep. Horstman's lively prose is packed with useful information: meditation increases attention while delaying aging; brain exercise and a strong social network decrease the odds of developing dementia; diet can quell morning crabbiness, increase afternoon focus, and promote sleep. Multitasking, as Horstman explains, is less like an efficient model of problem solving and more like channel-surfing; stress, she says, “may be the single worst thing your brain does to your heart.” Information-packed and fully referenced, this Scientific American publication is perfect for anyone with interest in mind/body interaction, mental health or aging. (PublishersWeekly.com, August 24, 2009) STARRED REVIEW Drawing on neurology articles from Scientific American and Scientific American Mind, science journalist Horstman creates a seamless and fascinating look at our brain's functioning throughout the day, adeptly noting cycles and processes that may occur by mentioning them in a time context that makes sense. Beginning her exploration at 5 a.m., when the brain begins to return to consciousness, she bases the chapters on each hour in a 24-hour period and groups hours into sections related to typical activities, such as "Winding Down" from 9 p.m. to midnight. She examines how and when other bodily processes and functions, such as hunger, impact the brain. Drops in blood sugar, for example, also indicate lowered levels of serotonin. The explanations are easy to read, and they incorporate anecdotes and callouts that deftly explain neuroscientific content. VERDICT Appealing to lay scientists, Scientific American readers, and all those interested in how to care for their brain as it matures and ages, this book will be a popular science title.
