Research Links Hands, Head and Heredity

Gays Give Big Brain

Gay people may be defined by their brains. And, no, we’re not talking about blow-jobs.

New research out of Toronto suggests a link between the size of a male subject’s posterior corpus callosum, which connects the left and right brain, to his sexuality. And, what’s more, their genetic make-up.

A neuroscientist named Sanda Witelson previously proved that gays are more likely to be left-handed than their hetero counterparts. Another Witelson-helmed study showed that left-handed people have a larger posterior corpus callosum. Taken together, these findings have led Witelson in a surprising and potentially telling new direction…

Via Sify News:

This raised the hypothesis for the current study: whether the anatomy of the brain of the sub-group of right-handed homosexual men is similar to that of left-handers.

The researchers found that the posterior part of the corpus callosum is larger in homosexual than heterosexual men.

As the size of the corpus callosum is largely inherited, it suggested a genetic factor in sexual orientation, said Witelson.

“Our results do not mean that heredity is destiny, but they do indicate that environment is not the only player in the field,” she said.

We always said the brain’s the sexiest part of a lover.
