This painting is about the prenatal development of the brain under the influence of multiple genes. The lught in the brain I've paibted is in the area where there is the INAH 3 nucleous, the structure responsable for our sexual orientation. This structure can be masculinised or not during the prenatal period under the inflence of the genes involved in the androgens metabolism and the Xq28 gene. Without masculinisation this structure will remain in the default female stage and the individual will feel attracted to males.
