Gay men seem to read maps in a similar way to women. Although this seems like an insigificant finding, it may help uncover some of the neural functions that are related to sexual preference, as these abilities are known to involve specific areas of the brain.
In fact, this isn’t the first study to find a similarities between gay men and women in spatial abilities. Result published in 2003 showed that both women and gay men performed better on a memory test for locations than straight men.
These sorts of abilities are known to rely heavily on area of the brain known as the hippocampus and differences in these abilities are likely to reflect differences in how these brain structures process information.
What is not clear however, is how much these differences can account for individual sexual behaviour. This is because sexual behaviour can be motivated by a wide range of different desires and motivations, all of which may be supported by complex network of brain structures. Few of these are currently known about or understood.
