Differences Related to Sexual Orientation Found in the Brain

A new neuroimaging study reveals brain patterns that differentiate between men and women are less pronounced in non-heterosexual people. The differences occurred primarily in sensory processing areas of the brain, in particular areas associated with visual processing. Researchers say the brain differences could be linked to a genetic predisposition for same-sex sexual behaviors. The study reveals a neurobiological basis for same-sex attractions.

New Clues About the Link Between Stress and Depression

p11, a protein implicated in serotonin function, affects the initial release of cortisol in mice by modulating the activity of specific neurons in the hypothalamus. Previous studies found people with depression lave lower levels of p11 in their brains. The findings could help in the development of new treatments for depression and stress.
