"In Pink Brain Blue Brain, neuroscientist Lise Eliot turns that thinking on its head. Calling on years of exhaustive research and her own work in the field of neuroplasticity, Eliot argues that infant brains are so malleable that small differences at birth become amplified over time, as parents, teachers, peers—and the culture at large—unwittingly reinforce gender stereotypes. Children themselves exacerbate the differences by playing to their modest strengths. They constantly exercise those “ball-throwing” or “doll-cuddling” circuits, rarely straying from their comfort zones."
