So why does the brain sometimes signal us to do stupid things, especially in regard to sex and relationships? Isn’t that a little like one conjoined twin punching the other in the mouth? How does the brain decide who attracts us? What is it doing behind our backs, and how do we change as we mature?
1. Size matters.
The preoptic area of the hypothalamus, which regulates mating behavior, is a little more than twice as big in men as it is in women and has twice as many cells. Medical Net says difference starts to show up when we’re about four years old.
