-El cerebro prenatal no comienza realmente a desarrollarse hasta entre la semana 12 y 24. La corteza cerebralThe cerebral cortex, the thin outer layer of the brain that contains most of what we think of as consciousness, grows substantially during those periods of time. Prior to that, the structure present is more like a scaffolding, the basic parts of the nervous system necessary for bodily function. The primary sulci (the wrinkles in the cerebral cortex that allow for more surface area) [start to form at week 14](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2989000/#Sec5title), well after the genitals have developed.

 It [has been confirmed multiple times](https://www.the-scientist.com/features/are-the-brains-of-transgender-people-different-from-those-of-cisgender-people-30027) via MRI studies that there are small but significant differences between cis male and cis female brains, differences which align with the gender identities of trans people in the study. Note, **this does not mean that anyone with those differences will have that gender**, because gender identity isn’t that simple, but it provides evidence that there is a clear difference in masculine and feminine brains.
