So I don't know if women's brains are biologically different to men's brains, but I do know that every brain functions differently as an individual, regardless of their gender. Although, some men and women tend to believe that they know what people of they own gender think, I bet no one single person can prove that they truly know what others of the same gender think, even if they have heaps of life experiences and/or professional training in reading people's behaviour, like the psychologist/psychiatrist. This is only my opinion and I have never claimed to be a medical expert lol - Posted from rhpmobile

I read a brilliant book called Brain Sex years back. Sorry cant remember the author's name but it is probably on google. The book cover many areas from how sexes perceived differently, how hormone levels in a pregnant woman could influence whether a child was born gay, lesbian or trans. It gave an amazing account of how male and female brains recover differently after strokes. From what I can remember the book described how the female brain stores parts of the same information on both sides of the brain whereas for men information is compartmentalized into its own section either on the left or right hand side. What this means is that if a female has a brain injury to one side of her head she can usually recover better and faster because, for instance, the speech sector is stored on both sides. Male brains compartmentalize information so if the speech area is damaged it is much more difficult to recover. There would have been newer studies out that have different findings. The brain is a wonderful organ and there is always new information coming out. LG

Belenky, Clinchy, Goldberger, and Tarule (1986) examined the epistemology, or "ways of knowing", of a diverse group of women, with a focus on identity and intellectual development across a broad range of contexts including but not limited to the formal educational system. While conceptually grounded originally in the work of William G. Perry (1970) in cognitive (or intellectual) development and Carol Gilligan (1982) in moral/personal development in women, the authors discovered that existing developmental theories at the time did not address some issues and experiences that were common and significant in the lives and cognitive development of women (Love and Guthrie 1999). While the developmental positions described in "Women's Ways of Knowing" overlap to a large degree with Perry's cognitive developmental scheme, the authors describe additional knowledge perspectives not observed in Perry's study (Perry 1970) and report gender-related influences on cognitive development in women.The 135 women who participated in Belenky, Clinchy, Goldberger, and Tarule's study ranged from age 16 to over 60, came from rural and urban populations, and varied in socioeconomic class, ethnicity and educational history (Belenky, Clinchy, Goldberger, and Tarule 1986, Love and Guthrie 1999). As such, they represented a more diverse group than was included in Perry's 1970 study of male students at Harvard. The authors illustrated how the epistemological assumptions of the participating women were intimately linked to their perceptions of themselves and their relationship to their world. Each of the five "ways of knowing", or knowledge perspectives, represents a different point in the women's cognitive development, dependent on conceptions of self (self), relationship with others (voice) and understanding of the origins and identity of authority, truth and knowledge (mind) (Belenky, Clinchy, Goldberger, and Tarule 1986, Love and Guthrie 1999). So yep, looks like we do learn and develop understanding differently to men.

All foetuses start off as female (hence men having nipples), so I would think their brains are no different in principle. I do agree though that brains are unique like fingerprints, but regardless of gender. It does raise the question for me though why some biologically male bodies are born with female brains and vice versa. It's not a difference in wiring when it comes to a particular gender's thought process, but I do wonder how it fits in. Not an expert either, of course.

The difference between the sex of a person and their gender. I dont believe its conditioning, I believe ppl are born with their gender and sexual orientation. Yes, I believe there is a major diferences between the genders in their thinking and emotional intelligence.

There has been loads of research done to indicate men and women brains are wired differently with varying arguments in between. Biologically speaking we both have the same brains, but how men and women use their brain is where the vast difference is, and which alot of Neuroscience journals will extrapolate on. Mens brains are wired from top to bottom whereas woman's brains are wired from left to right. It has been said over an over for many years that generally this is the reason why some men are no good at multitasking as compared to women. Having said that, I would say it is nature and through nurture as to the reason why we are wired differently.

I have a male brain with both male and female software. My female self has many female traits, feelings, emotions and mannerisms but is limited in some areas due to the male brain hardware. Plenty of research has been done with this in the transgender area but still lots of unknowns and variables.

In some ways....we DO think differently as a result of hormonal effects on developing brain tissue..... and the continuing effect of those hormones throughout our lives.... .... but as has been mentioned earlier.... its the social programming.... that more significantly effects the thoughts that lead to different behaviours. Take the negative effect of certain social programming away and thoughts and actions can be very much the same under the right circumstances. DG

"Women are wired differently not to think likk men" Sounds like male poster and a female had a misunderstanding, and he decided that it was all the women's fault. Rather than "man up" and take his share of the responsibility for communicating clearly.

evolution thats how we are wired the same but our controls are different . Female Newborns in the future of evolution will be born with both genitals of female and male and therefore females of the future will evolve to self fertilise there own eggs at a time when they mature or around the initial menstrual cycle. Males will still be born as we are wired the same and apart of human life cycle . This is why woman will become the superior race . This is why men suppressed women to put off the inevitable .

Till we reach puberty we are the same, apart from the inny and outy bits. Then hormones kick in and our brains undergo a period of culling, removal of unnecessary clutter. Environment has a big impact on how this reorganizing of pathways effects how we think. These changes are permanent and irreversible. These is no reliable method to determine sex from just looking at the brain. Though if we look at brain chemistry as a gender indicator it is much easier to determine, though not 100% accurately. When you consider gender reassignment via hormonal treatment, thought there is no evidence of rewiring there is strong anecdotal (we can not know what people think) evidence of differing thought patterns as a result. Apart from the transformation in puberty of the brain that is strongly influenced by environment, the human brain is identical between men and women. It is the chemistry of the brain that makes us what we are, anyone that has had mind altering chemicals will know how dramatic this change can be. Giving women testosterone makes them more aggressive, giving estrogen (think that is the right one) to men makes them more social and nurturing. We are not wired differently, we are just high on our own supply off male or female drugs. As each of us produce these are differing rates at differing times, the state of our gender specific thought process is in a constant state of flux. All it takes is hormonal treatment to change us from man to woman or woman to man. If it where structural (wired) then this would not work, as past the age of 21 (about) the human brain changes little. Though in "wired" I think the OP refers not to a physical attribute but that of how we think. To which science has a lot to learn, too much in fact to call it anything but guess work.

Quoting 'johnhadd' Sexual Dimorphism? According to the Encyclopedia Britannica sexual dimorphism is "the differences in appearance between males and females of the same species, such as in colour, shape, size, and structure, that are caused by the inheritance of one or the other sexual pattern in the genetic material." I don't think that relates to the anatomy of the brain, or any thought processes stemming from it.

Without genetic diversity, through the interaction of different genes supplied by more than one "parent", there is no opportunity to adapt to changing environments, and pass on the successful genes.

And increasingly more feminine , So sexual penetration will become eradicated for breeding , and man will become ? Entertainment ! Sex ! Slaves ! Suppressed ! Just as women have been in the past .

I will weigh in with my 2 cents and say I believe a lot of our societies and there pressures to fit certain moulds effect thought processes in both males and females and that changes generation to generation. it's not until we're older that we start to make our own distinctions As to who and what we are. I'm loving the newest thought process evolving that is breaking down gender bias in all areas of culture not just sexual stigmas. Daz

On a side note RE reproduction.Sexual reproduction was a evolutionary leap forward. It allows for greater diversity and thus gives a species an evolutionary advantage. Some have speculated that without sex we would still be slime in a pond. There is no advantage to asexual reproduction unless population levels are very low. It is now possible to have 3 parents, one for the sperm, one for the egg, and one for the mitochondrial DNA. The reason for doing so is because defective mitochondrial DNA can lead to host of mitochondrial diseases. In the past this genetic info was always inherited from the mother, now you can have a mother and two fathers, or even two mothers, one for the egg the other to carry the child, and two fathers (male or female). There is a strong case to say 3 or more parent inheritance is good for a species. It is way to early to tell if the brains of people of 3 parents have any significant differences. Scientist are close to the creation of female sperm and male eggs. Though for females the task is hampered due to the lack of stem cells in the ovaries required to create the sperm, in men the testicles have a ready supply of stem cells which can be induced to create eggs. Conflicting reports though are the norm here as in many countries this type of research is considered unethical and illegal. There is no reason that 2 or 3 males can not produce fertile females. Though still needs a womb. Remember that all males also carry at least one X chromosome, two of which are required to create a woman. While for women creating male offspring may not be possible due to the lack of the Y chromosome, though some would argue "Why bother!" The biggest and most reliable contributing influence on brain development is genetics. This does not mean behavioral, the animal brains is designed to adapt, its plasticity is what allowed us to build the world we live in. As a male your brain is closer in structure to your mother, than another random guy, and the same with females, your brain is closer to your father than a random female. (ignoring chemistry)

More info. The female brain on average is 90% the size of the male brain. (ref theguardian, science, neurophilosophy, 2013 oct 06 male-brain-versus-female-brain) Differences; (Cerebral cortex, the higher functions ) Women tend to have slightly greater grey matter to white matter ratio then men, and the cerebral cortex is slightly more convoluted than in men. Grey matter is the functional part of the brain, while white matter is the wiring. Increased convolution increases the surface area of the brain and is directly linked to nerve cell count and grey matter. In men the Hippocampus (right down inside and involved in memory, both long and short term cognitive memory (remembering names), does not play much part in muscle memory (riding a bike) ) is slightly larger in men. In men the Amygdala (Deep inside, involved in memory, decision making and emotional reactions) is slightly bigger in males. The most prominent difference between men and women is the Third Interstitial Nucleus, a tiny structure at the base of the brain in the hypothalamus. It is on average twice as large in men as in women. Though it is unknown what its function is, it has been found to be linked with gender identity. Structure this deep in the brain are very primitive. So all up men have slightly larger brains and subsections. What does this mean. Sweet F all. It is brain nerve density that matters, men have bigger brains because they have bigger heads, women make up for it by increasing grey matter and folding. Its a issues of real estate. We have equal nerve counts (should say guesses as nobody is really sure) That's what the world of science has to say about the Male Female brain in terms of structure, minor differences more related to the size of your head than the bits between your legs. Though I am going to have a deeper investigation of the Third Interstitial Nucleus as there is some interesting (inconclusive) data linking it to sexual identity and gender Identity. Find it all on Wiki, via google, or scholar dot google

Quoting 'Bigocean' Fail to change Fail to survive Exactly , Evolution has an end Extinction . You keep using that word. I do not think it means what you think it means. Not even close to "exactly". Evolution, by very definition, means change.... and that change is driven by the goal to diversify the genes sufficiently to ensure their continued existence..... the goal is to prevent extinction and further the existence of the genes.

This wednesday night is a typical example..... There will be some women out there thinking, god i wish my boyf/husband/fwb/casual would just fuck me and fuck me hard during the game on wednesday night? Men can randomly out of the blue just want sex? how many women can claim out of the blue they just want sex without initially reading/imaging/fantasing about a guy or sex. These are just two standard examples......... Hence why we are biologically different, however some will argue and only a tiny minority that some women do think like men vice versa.

If women can think like a man? Why do we have alot of forums where both women and men are both trying to analyse why/how both men/women can think/act the way they do? As much as you try and learn about the other sex, you will always be left out in the cold. Pscyhologist as much as they try and think they know the other sex, they still can't map out someone's thought process. Just when you think you know someone, they will in fact change their behaviour.

I'm no expert but here goes.... The female brain has a greater number of connections between the hemispheres (studies on intuition turned this up IIRC). Other studies have shown that the female brain is more active when at rest than the male brain under load (based on blood flow via MRI scan I think). So yes, the male and female brains are different.

Genetic diversity may be one of the main drivers of evolution, but it's not its goal. Evolution has no particular goal, or purpose, or aim, whether that is to achieve or prevent something. That it does have a goal or purpose, or that it acts in a particular direction, are some of the commonly held myths about it.

A while back I watched a several part doco on Masters and Johnson and their research into sexuality in males and females. They did an experiment with many participants on male and female visual stimuli. They used many sexual activities and pictures using electrodes hooked to the brain. When they showed footage of Bonobo chimps having sex the males did not respond but interestingly enough all the females did. Which led them to conclude, contrary to belief, that women were more visual than men. Wonder if anyone else caught that doco

Do have men and women different chemicals in their brain? Apparently not. This is from PsychologyToday: "Male and female brains process the same neurochemicals but to different degrees and through gender-specific body-brain connections. Some dominant neurochemicals are serotonin, which, among other things, helps us sit still; testosterone, our sex and aggression chemical; estrogen, a female growth and reproductive chemical; and oxytocin, a bonding-relationship chemical. In part, because of differences in processing these chemicals, males on average tend to be less inclined to sit still for as long as females and tend to be more physically impulsive and aggressive. Additionally, males process less of the bonding chemical oxytocin than females. Overall, a major takeaway of chemistry differences is to realize that our boys at times need different strategies for stress release than our girls." So according to this article we have the same chemicals, we just handle them differently.

I found an article from TheGuardian very interesting, here is most of it*: "Summary: Subtle observable differences exist between male and female brains, but how exactly these relate to differences in behaviour is unknown. Such gender variations in the brain are often exaggerated and misappropriated, not only by the mass media but also by scientists, to reinforce stereotypes and perpetuate myths. The science of sex differences has always been – and still is – fraught with controversy. Some believe that behavioural differences between men and women are mostly due to cultural influences, while others argue that sex differences are largely determined by biology. In reality, the situation is far more complex. It lies somewhere in the middle, and involves two related but independent factors, which are often confused or conflated. One of these factors is biological sex, which is determined by chromosomes. Most people have either two X chromosomes, which makes them female, or one X and one Y chromosome, which makes them male. The other is gender, which is influenced largely by the socialization process. As we grow up, we learn society's norms about how males and females look and act; for most people, sex and gender are matched, and so they inadvertently conform to these norms. Men and women's brains differ in subtle ways, and these differences are probably established in the womb, due to the effects of sex hormones, which masculinize or feminize the organ as it develops. However, we still do not understand the effects of sex hormones on the developing brain, or how the subtle differences observed between men and women's brains are related to differences in their behaviour. Battle of the sexes?The most obvious difference between the brains of men and women is overall size – men's brains are, on average, between 10 and 15 per cent larger than women's. In one recent study, neuroscientists compared the brains of 42 men and 58 women postmortem, and found that men's weighed an average of 1,378g (3lb), compared with 1,248g (2.75lb) for women. These size differences have been found repeatedly, but they emerge only when comparing large numbers of people, so some women's brains are larger than the average whereas some men's are smaller. These differences partly reflect the fact that men are generally bigger and taller than women, but they are not related to differences in intelligence. Men and women's brains also differ in overall composition. Male brains tend to have a slightly higher proportion of white matter, whereas those of females have a higher proportion of grey matter in most parts of the cerebral cortex. Consequently, the cortex is slightly thicker in women's brains than in men's and, according to several studies, is slightly more convoluted as well. There are also sex differences in the size of individual brain structures. The hippocampus, a structure involved in memory formation, is on average larger in men than in women, as is the amygdala, which is also involved in memory, as well as emotions. Another sexual variation is found in a structure called the third interstitial nucleus of the anterior hypothalamus. The function of this tiny structure is unknown, but research from four different laboratories has repeatedly found that it is almost twice as large in males than in females. It has also been linked to sexual orientation and gender identity: one study showed that it is more than twice as large in heterosexual males than in homosexual males, where it more closely resembles that of women; another found that it is smaller in male-to-female transsexuals, and larger in female-to-male transsexuals. These studies have been criticized for their small sample sizes, and the findings have not been confirmed. Stereotypes and mythsNumerous studies show subtle differences in male and female behaviour and in cognitive functions, too. Men tend to be more aggressive and outperform women on mental tasks involving spatial skills such as mental rotation, whereas women tend to be more empathetic and perform better on verbal memory and language tasks. Findings like these are often exaggerated to reinforce the stereotypes that women are bad at reverse parking and that they love to chat! In some cases, individual studies purporting to show sex differences in certain tasks are misappropriated. For example, according to a tiny postmortem study published in 1982, the corpus callosum, the massive bundle of nerve fibres connecting the two brain hemispheres, is proportionally larger in women than in men. This was widely reported to mean that women are better at multitasking, even though subsequent work has failed to replicate the results. A more recent study showed that women are marginally better than men at paying attention to sounds presented to both ears simultaneously – this was interpreted by some as evidence that 'men don't listen'. Many of these claims are accompanied by the assertion that the observed differences between men and women's brains are 'hard-wired' and, therefore, irreversible. We now know, however, that brain structure and function change in response to experience, so any observed differences between the brains of men and women could also be due to differences in upbringing and socialization. To date, though, very little research has been done to investigate how different nurturing styles might influence brain development." * The last part spoke of austism and left it out as I didn't think it was relevant, but it's easily found via Google.

Quoting 'Luck_Dragon' Quoting 'Mischeviouslad'Genetic diversity may be one of the main drivers of evolution, but it's not its goal. Evolution has no particular goal, or purpose, or aim, whether that is to achieve or prevent something. That it does have a goal or purpose, or that it acts in a particular direction, are some of the commonly held myths about it. IT does have a goal... of sorts.... but its not a goal as we humans perceive goals. Genes want to exist for the sake of their future... so they drive behaviours which encourage this continued existence.Diversity is a byproduct of these driven behaviours. And BO... Quoting 'Bigocean'so what happened in your genes ?? Mistake Dont fret we all make mistakes. Whats that?Ya got nuthin?Hmmmmmmmmm

Quoting 'Luck_Dragon' Quoting 'Mischeviouslad' Evolution, by very definition, means change.... and that change is driven by the goal to diversify the genes sufficiently to ensure their continued existence..... the goal is to prevent extinction and further the existence of the genes. Genetic diversity may be one of the main drivers of evolution, but it's not its goal. Evolution has no particular goal, or purpose, or aim, whether that is to achieve or prevent something. That it does have a goal or purpose, or that it acts in a particular direction, are some of the commonly held myths about it. bingo. "goal" is an awkward term, it implies some sort of conscious thought/sentience. You wouldn't expect to see mortal systems that can't reproduce because as soon as it dies, it is gone - systems that reproduce might not last longer themselves, but that species will last longer.Genes that result in furthering the existence of a creature are what you'd expect to see because otherwise they'd be less likely to be passed on. If you have 2 drivers for genetic change from generation to generation - random mutation, and inheritance, then if random mutation is sufficiently low, inheritance will be the major driver for change and is the fastest way to have a larger number of 'solutions' tested for fitness to an environment. So you might get some spectacular failures, but more likely to hit on something that survives, faster than if the only driver was mutation. But genetic diversity isn't everything, if a species had the right makeup to survive well, there isn't any benefit to its survivability if there were any genetic changes. Diversity just results in more 'experiments' to see which survives. (Though here, phrasing is awkward in the same way as using "goals" - "testing", "experiments", "solutions" all sound like there is some being watching over it, and a consciousness to the processes) Quoting 'Slickz' Out of curiosity, it seems like you have some type of science background. How about A-sexual pathogens or bacteria - how do they evolve without genetic diversity? besides random mutations, bacteria can directly absorb other genetic material

If I had of been born with male genitalia? Don't we all have oestrogen and testosterone? Isn't it just the varying degrees of these hormones that give us our male/female persona? All the rest of it just seems to be a result of social conditioning, to me at least. I don't know if that's right or wrong, it's just the way I think.

It depends on the amount of testosterone the foetus absorbs in the first 10 weeks of growth. The testosterone is not only absorbed into the cells which are just forming a body but into the brain cells. Quoting 'Meander' All foetuses start off as female (hence men having nipples), so I would think their brains are no different in principle. I do agree though that brains are unique like fingerprints, but regardless of gender. It does raise the question for me though why some biologically male bodies are born with female brains and vice versa. It's not a difference in wiring when it comes to a particular gender's thought process, but I do wonder how it fits in. Not an expert either, of course.
