Brain imaging studies have shown that transvestites have bigger brains than men who do not cross dress.
"It was a spot on correlation," said neurologist, Matt Paynter. "Men who cross dressed seemed to have bigger brains."
Neurologists are putting this down to the fact that cross dressers have two people in their heads, but are not schizophrenic. Whether this combination is possible because they have bigger brains, or the act of holding two lives in one head creates the bigger brain, we don't know."
Because there is not a strict delineation between the two lives, as there is with schizophrenia, more space is required to hold all of the information needed to be both male and female.
"Men need to know how to shave a face and kick a football," said Paynter. "Whereas, women need to know what colour complements coral and how to apply blusher correctly. There is some overlap between what males know and what females know. But it's only slight. Even walking's different."
According to the study cross dressers have to be able to switch between applying lipstick and putting up a shelf. This switching requires extra brain power.
"What we need to untangle," said Paynter, "is the order. Do people who end up cross dressing end up gaining extra brain mass? Or do they start with the extra brain mass, and fill it with the need to cross dress?"
Also to answer the question is that those who go onto become women, do they have larger brains? Do the brains shrink once the decision is made? Or later? Or not at all. Also needed to know is if the extra brain power provides more than the ability to select soft furnishings and go as week without showering.
"There are still plenty of questions to answer," said Paynter. "I'm looking forward to getting the questions asked."
