Our sense of belonging to the male or female gender is an inherent component of the human identity perception. As a general rule, gender identity and physical sex coincide. If this is not the case, one refers to trans-identity or transsexuality. In a current study, brain researcher Georg S. Kanz of the University Clinic for Psychiatry and Psychotherapy of the MedUni Vienna was able to demonstrate that the very personal gender identity of every human being is reflected and verifiable in the cross-links between brain regions.
While the biological gender is usually manifested in the physical appearance, the individual gender identity is not immediately discernible and primarily established in the psyche of a human being. As the brain is responsible for our thoughts, feelings and actions, several research institutions worldwide are searching for the neural representation of gender identity.
In a study under the guidance of Rupert Lanzenberger of the University Clinic for Psychiatry and Psychotherapy of the MedUni Vienna published in the renowned magazine Journal of Neuroscience it was now possible to demonstrate neural correlates (analogies) of the identity perception in the network of the brain.
