Neuroscience and Sexual Orientation - Related Studies

Related Studies

Various animal and insect models have been used to explore sexual orientation and brain characteristics. One experiment involved genetically altering male Drosophila causing them to have feminized brain structures involved in processing sexually dimorphic contact pheromones. Transformed males showed increase homosexual courtship behaviors to wild-type male flies, and there a correlation was found between the courtship behavior and the expression of the altered gene in the sexually related brain regions.

A 2004 study exploring the difference in brain metabolism between heterosexual and homosexual males found that homosexuals had a significant reduction in hypothalamic glucose metabolism compared to that of heterosexuals with other brain regions including the prefrontal association cortex and portions of the cingulate cortex showing differences in the measured activation.

Famous quotes containing the words related and/or studies:

    The custard is setting; meanwhile
    I not only have my own history to worry about
    But am forced to fret over insufficient details related to large
    Unfinished concepts that can never bring themselves to the point
    Of being, with or without my help, if any were forthcoming.
    John Ashbery (b. 1927)

    Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.
