Further research should probe whether human mothers treat sons and daughters differently, and what effect, if any, that has on brain development. Mother rats spend more time licking and grooming their sons for example, which previous studies suggest is necessary for their genitalia to form properly.It might help to explain why some conditions affect the two sexes unequally. Depression is twice as common in women as in men, for example, and men and women respond differently to head injuries, strokes, Parkinson's and Alzheimer's disease.
