This is your brian straight this is your brain gay

We examined potential cerebral structural differences linked to sexual orientation in a group of 74 participants, including 37 men (21 homosexual) and 37 women (19 homosexual) using voxel-based. That said, as others have commented, your personality is largely determined by the neurological structure of your brain (up to and including sexual orientation).

They found that in gay men and women, the blood flowed to areas involved in fear and anxiety, whereas in straight men and lesbians it tended to flow to pockets linked to aggression.

Gay brain vs straight brain

The brain region that showed the most consistent sexual orientation‐related differences in both male and female homosexuals was the calcarine sulcus. Sexual differentiation of the human brain: relation to gender identity, sexual orientation and neuropsychiatric disorders. Frontiers in neuroendocrinology, 32 (2), What does All of Us Strangers say about being gay?

The investigators also discovered an interesting trend with regard to the linkage between genetic patterns and changes in brain anatomy. The images revealed how the amygdala connected to other parts of the brain, giving clues to how this might influence behaviour. In spite of these interesting findings, the authors emphasized that genetic or neuroimaging data cannot be used to predict an individual's sexual orientation.

The problem was that there was no way to determine whether their responses were colored by learned social cues. Now we know that we need protections. June 16, 2 min read.

They found that the patterns of connectivity in gay men matched those of straight women, and vice versa see image, above right. Essentially, the differences in brain anatomy that distinguish heterosexual males and females were present, however they were less pronounced when comparing male and female homosexuals. For at least 20 years, neuroscientists have been trying to discover whether there are specific anatomical differences between heterosexual and homosexual men and women.

Join Our Community of Science Lovers! The data also identified certain trends, including that gay men had narrower jaws, longer noses and larger foreheads than straight men, and that gay women had larger jaws and smaller foreheads compared to straight women. To get around this, Savic-Berglund focused on the structure and function of brain regions that develop during fetal development or early infancy—without using any cognitive tasks or rating systems.

This type of research further raises concerns about the potential for scenarios like the science-fiction movie Minority Report , in which people can be arrested based solely on the prediction that they will commit a crime. Sexual Orientation Brain Differences Linked to Sexual Orientation A recent study linked genetic and brain anatomy changes to sexual preference.

In straight women and gay men, the connections were mainly into regions of the brain that manifest fear as intense anxiety.
