What's Going on in There?: How the Brain and Mind Develop in the First Five Years of Life

With impressive depth and clarity, Eliot, a neuroscientist and mother of three, offers a comprehensive overview of current scientific knowledge about infant and early childhood brain development. Beginning with a richly detailed yet accessible tour of the growing embryo, she guides the reader through the sensory, motor, emotional and cognitive systems as they develop. She builds up a versatile toolbox of scientific concepts and vocabulary as she goes, outlining entire neuroscientific subfields with remarkable efficiency. Along the way, Eliot presents research results on almost every conceivable topic of interest to the curious parent, from the potential dangers of VHF exposure in utero to sex differences in olfaction after birth (females have a better sense of smell than males), to the fascinating possibility that birth is triggered by a hormonal cascade in the baby's brain. While Eliot does not scruple to offer parenting advice where she finds it appropriate (e.g., she advocates breast-feeding), she meticulously avoids comment on thornier social and ethical issues. Her neutral tone can be disturbing at times, as when she admits positive correlations between socio-economic status and IQ or details Nobel prize-winning research into binocularity that involved sewing kittens' eyes shut at birth, without reference to animal rights objections. Eliot's confidence in the open-minded interest of her readers makes this a good bet for scientifically oriented parents who want to grasp how a child's mind develops. All in all, this is popular science at its best. (Sept.)
