Study Confirms Differences Between Men’s and Women’s Brains

The research, conducted with mice, led by Margaret M. McCarthy and recently published in the journal Neuron, may now help researchers better understand the differences in behavior development between men and women. Men, for example, tend to be more aggressive and to a large extent prefer tougher games.

One key piece that distinguishes men and women in terms of their playing behavior is the difference in the number of new cells born in the tonsil, a brain area that controls emotions and social behaviors. The research showed that male mice have less of these newborn cells, as they are actively eliminated by immune cells, something that doesn’t happen in female mice.
