There are many different nonscientific answers to this question. A wife might argue that her husband uses less than 10 percent of his brain at times, a coach often tells his players that they aren't using their heads enough, and we often think that our politicians don't use their brains at all. The truth is that there is no way to quantify how much of our brains we use at any given time. Humans definitely use more than 10 to 20 percent of their brains, so this myth is definitely false.
In the September 2005 issue of the journal Neuroimage, psychiatric researchers at the University of Sheffield reported that male and female voices activate distinct regions of the male brain. The scientists monitored the brain activity of twelve men as they listened to male and female voices. They found that in men, women's voices stimulate an area of the brain used for processing complex sounds, like music. Male voices, on the other hand, activate a region of the brain used for producing imagery. This may suggest that, at least for men, the female voice is more complex and more difficult to hear and understand.
