that female and male brains are very similar, but at the molecular level, there are clear s*x differences that could show us paths to develop targeted drugs? "I’ve come to think that s*x differences in the brain could be very important. Less for figuring out how our minds work and more for ensuring that we maximize the benefits of science for medicine,” says neuroendocrinologist Catherine Woolley. She goes on to debunk a common theory that male brains are larger than female brains, stating that the difference in brain size between males and females is actually not significant. While overall structural differences may be minimal, s*x differences at the level of molecular mechanisms are much more meaningful. Estrogen, for example, acts in a part of the brain related to emotions, learning and memory (the hippocampus) to achieve the same end-result in both males and females but acts through different mechanisms.
