Sex Differences in the Brain: The Not So Inconvenient Truth
Margaret M. McCarthy, Arthur P. Arnold, Gregory F. Ball, Jeffrey D. Blaustein, and Geert. J. De Vries
The arguments for studying sex differences in the brain are as follows. (1) There is compelling evidence of pervasive and robust differences between males and females in both normal and pathological conditions. (2) The number of published studies limited to males remains stunningly and stubbornly high (Zucker and Beery, 2010). Scientific conclusions based on the study of one sex could have limited value in understanding some phenomena in the other sex. Thus, females deserve more study. (3) In addition, direct comparison of the two sexes is beneficial because of the unique perspective it offers.
