From The Brain Book by Rita Carter.
There are a number of structural and functional differences between male and female brains.
The human brain is divided into two hemispheres that do different things. They are connected by the corpus callosum, a thick band of nerve tissue that carries information between the two.
This band of nerves is slightly larger, on average, in women than in men – which means the emotional right side of the brain is better connected to the analytical left side.
This may be why women are more emotionally aware. It may also allow emotion to be incorporated more readily into thought and speech.
When doing complex tasks, women use both sides of their brain, while men use the side more obviously suited to the task.
To test your corpus callosum, try the following: Close your eyes and spread out your hands, palms facing upwards. Get someone to touch one of your fingertips (say, on the right hand) and with your opposite hand try to touch the corresponding finger with the thumb of the same hand.
If information is flowing properly between the hemispheres, you should be able to do this without opening your eyes.
I’m thinking that there are easier ways to tell the difference between men and women.
Well, the way I heard it, it’s because us men make them.
