Is the corpus callosum in a woman's brain have more connections than a man's?

Yes. The corpus callosum in women is on average 23% larger, which means that the two hemispheres of the brain can communicate with each other more effectively. The advantage that women have because of this is that they can multitask better than men as well as talk about their emotion. This is because the speak producing and language processing occurs mostly in the left brain, and our emotions are mostly processed in the right brain. The advantage a male brain has is that it is able to focus on single tasks with logic. though they are less likely to talk about their emotions.
