Ponsonby Britt posted:Fake edit: actually, I think many feminists would conceptualize biological sex as a continuum rather than a dichotomy. "Male" and "female" are not closed boxes, but two poles around which most individuals cluster. There are various kinds of intersex person living in the middle - what does "sexual dimorphism" mean to someone with an XXY makeup? But I don't think any feminists would deny that most individuals have most of the characteristics of either "male" brain structure or "female" brain structure, which seems like the spirit of your question. (Again, not a neuroscientist, if someone is please correct me.) Neuroscience time! The brains of men and women do exhibit degrees of sexual dimorphism much as bodies themselves do, with some areas of the brain varying to different degrees. You're right in that there's not a binary situation but rather a continuum on which the brain lies, with one range considered more typically 'male' and the other 'female'. In particular, the interstitial nucleus of the anterior hypothalamus (INAH 3 to be specific) is known to show a considerable amount of dimorphism, analogous to the SDN-POA in rats. Studies have shown that trans people often have INAH 3 makeups closer to the range of their identified gender as opposed to their 'physical' sex. That said, while brains do exhibit sexual dimorphism physically, that doesn't necessarily translate directly to any functional dimorphism. Like any neural correlates of behaviours or consciousness, we don't know what effect, if any, these variations have. Pussy Cartel fucked around with this message at 22:51 on Jun 19, 2014 |
