This show is from CBS. This show said that there are brain size difference between male and female. There are 2 types of matter in the brain called gray matter and white matter.

The show said male have 6.5 times more gray matter than female do, and gray matter is part of the responsible for information processing. On the other hand, Female have as much as 10 times as much white matter than male do, and white matter is the part of the responsible for connecting information processing centers. So male might be better in math, and female might be better multi-taskers : people who can perform multiple tasks at one time.

Can you imagine that men have 6.5 times more gray matter and women have 10 times as much white matter? No way!!! I've never heard those incredibly big difference between male and female. Basically, human have a same brain. I've heard about some research found some small size difference between male and female brains; however, there are no big difference male and female brains. So if there are some original papers,  I guess the original paper said that male have 6.5% more gray matter than female do, and female have 10% more white matter than male do. Of course, there many brain size difference between animals. For example, whales have bigger brain than human. Of course, whales have bigger brain than human because whales are bigger than human. But brain size doesn't matter! This is because, even though whales have bigger brain than human, humans are more smart than whales. So the most important thing is connection of neurons. In short, I think there might be small size differences between male and female; however, brain size doesn't matter. So I think there no difference between male and female brains! If you have time, please check the website that I posted. It's few minutes show.
