BOOKMONGER Variations of a brain BY BARBARA LLOYD McMICHAEL In a time when the United States seems increasingly polar- ized, along comes a University of Washington professor who has written a book that may, in its own way, provide a key to bridging some of the chasms that seem to have developed between the folks who live in red or blue states of mind. That’s because this book has nothing to do with politics. “The Neuroscience of You” is a tour through research that Chan- tel Prat has conducted on how brains function. The neuroscientist quickly demonstrates that binary left-brain and right-brain think- ing is a simplistic and unhelpful approach to a complicated topic. That topic is one that, paid enough attention, could reveal more useful ways of relating to one another. In surprisingly winsome fash- ion, and often with self-deprecat- ing humor, Prat points out that while conventional neuroscience tends to focus on finding com- monalities about how the brain works, she thinks it could be more useful to explore the differences that distinguish how individ- ual brains function. Prat is inter- ested in how those differences can impact “not only the way we see the world but the decisions we make about how to behave in it.” Nature and nurture both play a role, as does internal chemis- try. Prat notes countless variables that figure into the way individuals comprehend and respond to stim- uli and situations. In the first section of the book, she discusses how the human brain’s physical configuration of two hemispheres is typically pretty lopsided. This degree of asymme- try – which can vary a great deal from one brain to the next – influ- 14 // COASTWEEKEND.COM ences the way the brain processes information. But Prat also points out that everyone’s brain possesses a unique mix of neurotransmitters: chemical messengers like dopa- mine and serotonin. Those, cou- pled with substances like alco- hol, caffeine or nicotine that an individual might choose to con- sume, also shape responses and decision-making. Over the course of this book, Prat offers readers a series of sim- ple tests to understand more about how their own brains operate. And she addresses the phenomenon of confirmation bias, the tendency to seek out individuals and ideas similar to our own. But the author encourages readers to try harder to understand the motivations behind different points of view. This week’s book She calls this “The Neuroscience of “mind-mind- You” by Chantel Prat fulness,” and to Dutton – 380 pp – $28 help us figure out how other peo- ple might arrive at conclusions that are different from our own, she lays out steps for reverse-engineering what other folks’ brain decision-making pro- cess must have been. (This is per- haps an unintentionally creepy way of phrasing what seems to be a sincere call for more empathy.) Throughout “The Neuroscience of You,” Prat serves as a cheerful and generous guide. But neurosci- ence is no stroll in the park. This reader, for one, is going to have to revisit the concepts in this book repeatedly before it all soaks in.
