The Difference in Brain between Men and Women

I'm reading  Why Mars & Venus Collide by the author of the well-known Men Are From Mars, Women Are From Venus, and impressed by the differences of men's and women's brain structure. 

I'm particularly impressed by this: 

"A woman's brain has a larger corpus callosum, the bundle of nerves that connects the right and left hemispheres of the brain. This link, which produces cross-talk between the hemispheres, is 25% smaller in men. In practical terms, this means men do not connect feelings and thoughts as readily as women do. In a very real sense, women have superhighways connecting their feelings to speech, while men have back roads with plenty of stop signs. Some researcheers believe that the integration of the two lobes may be the source of "women's intuition" - in other words, whole-brain processing. This stronger connection between different parts of the brain increases a woman's ability to multitask."

I just copy and paste the whole paragraph from the book.
