Therefore, LeVay believed that this difference in the hypothalamus structure was critical in distinguishing these two disparate groups of individuals, thereby providing ample support for the nature component to this hotly contested topic 2. The anterior commissure is a part of the brain in the midline of the two hemispheres that connects the two together with a bundle of nerves.
His study was conducted on over 50 pairs of brothers who were homosexual. It seems appropriate to end this semester with a topic that focuses on one of the fundamental questions raised in the first week of classes: Of all the experiments and results that I researched for this paper, I think this finding is the most coincidental.
This conglomeration of cells was identified as the interstitial nuclei of the anterior hypothalamus 3 INAH3.
However, another form of sexuality is homosexuality or gay, which is when a person desires to be in sexual relationships with those of the same gender, in other words, when a man prefers to be with men, or a woman prefers to be with women.
For example, as parts of the brain are used, cell death may be induced as well as the establishment of new connections between cells. Allen and Gorski found the differences originated in the anterior commissure AC of the hypothalamus.
According to this article, a study was conducted on the mothers of homosexual men that focused on the fertility of the mothers, and how it could possibly pertain to the source of homosexuality.
Michael Bailey and Richard Pillard furthered the aforementioned results on twins, by examining monozygotic twins identicaldizygotic twins fraternalas well as non-related adopted brothers. The cluster of cells was identified to be the sexually dimorphic nucleus.
Do you think that because attitudes are changing and acceptance of the LGBT community is becoming more prevalent, people are more willing to accept the possibility that sexual orientation is determined biologically? It works with many other parts of the brain, and plays a significant role in the operation of the sensations, especially pain.
Because we are hardwired to be gay, goes the theory, it is pointless for anyone to attempt to convert us to being straight. Perhaps the noted structural changes were induced as a result of the illnesses incurred by the individuals 1.
The first psychological test undertaken to determine whether there was a biological explanation for homosexuality was in Androgens were first discovered in and are steroid hormones responsible for the stimulation and development of masculine characteristics in vertebrates.
I found it quite intriguing that most of the research published on homosexuality has been on heterosexual women, frequently neglecting homosexual women. Submit an article Sexuality: Based upon the fact that there is such a gross differential brain organization in homosexual versus heterosexual individuals, this seems to be the most valid and plausible explanation.
He examined family trees and noticed a maternal link and then decided to collect 40 DNA samples from self-proclaimed homosexual men.
Therefore, I have addressed the nature versus nurture debate that we have spent many class discussions as well as many forum postings talking about. The subjects were then given three psychological tests: There have been numerous studies designed to determine whether or not homosexuality has a genetic cause.
Brain usage could not have altered these structures that much; instead it seems more likely that the individuals were born this way. In addition, gay women and straight men also share brain similarities, such as the increased number of nerve connections, on the right hemisphere of the brain, of amygdale, which is a part of the brain that is responsible for some emotions, memory, and visual learning.
This was, he suggested, proof of natural sexuality. Is our sexuality really something genetically imposed on us that we have no control over? He believed that homosexuality was only created about years ago and that there were only two distinctions: If this is so, it does not make sense that someone can be raised to be homosexual or heterosexual; instead, we are packaged in such a way that these characteristics are inherent.
These are the sort of bench scientists, where I am more interested in clinical things. It also suggested the possibility that the mothers of several children, mostly male, became progressively resistant to the Y chromosome, which is the male chromosome.Oct 08, · Geneticists suggest that together, the human genome and its epigenome reflect the interaction of nature and nurture -- both our fixed inheritance and.
The homosexual community has to live with discrimination due to the opposing views. The debate remains just that, a debate. When one theory seems to be a success, another one comes along and thrashes the common belief.
Nature vs Nurture Concerning Homosexuality. form of sexuality is homosexuality or gay, which is when a person desires to be in sexual relationships with those of the same gender, in other words, when a man prefers to be with men, or a woman prefers to be with women.
However, there are those – medics, social constructionists, radical feminists, postmodernists and, incongruously, rightwing anti-gay bigots – who believe that sexuality is nurture not nature.
This nature versus nurture debate has been one that we have discussed extensively in class. In order to resolve some of the questions that I have concerning this matter, I decided to dedicate this paper to analyzing nature versus nurture in terms of homosexuality.
Nature vs. Nurture: The Biology of Sexuality But he's not saying it's % nature or nurture. To “Maybe you should also”: The speaker is not saying that it is % nature or nurture. I think he is saying that nature plays a big role, and now we have stronger evidence to confirm this. This does not imply that it is all nature.Download
