Neuropsychiatrist Louann Brizendine follows up her much-discussed The Female Brain with this frank and well-researched look at the male counterpart. Brizendine acknowledges that… the human brain is enormously malleable, and considers how much of the gender divide is due to nature and how much to nurture. But in the end she finds she can’t get around fundamental differences in the male brain—such as the fact that the area devoted to sexual pursuit is 2.5 times larger than that in women. The Male Brain tracks its subject through the entire lifespan of a man, paying particular attention to the shifting role of hormones. How to describe the ride in this great psychology book? Provocative, learned, and entertaining.
