Males and Females Differ in Specific Brain Structures

Medical Xpress, February 11, 2014

Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews.

The team, led by doctoral candidate Amber Ruigrok and Professors John Suckling and Simon Baron-Cohen in the Department of Psychiatry, performed a quantitative review of the  imaging literature testing overall sex differences in total and regional brain volumes. They searched all articles published between 1990 and 2013. A total of 126 articles were included in the study, covering brains from individuals as young as birth to 80 years old.

They found that males on average have larger total brain volumes than women (by 8-13%). On average, males had larger absolute volumes than females in the intracranial space (12%; >14,000 brains), total brain (11%; 2,523 brains), cerebrum (10%; 1,851 brains), grey matter (9%; 7,934 brains), white matter (13%; 7,515 brains), regions filled with cerebrospinal fluid (11.5%; 4,484 brains), and cerebellum (9%; 1,842 brains). Looking more closely, differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.

Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.

By contrast, females on average had higher density in the left frontal pole, and larger volumes in the right frontal pole, inferior and middle frontal gyri, pars triangularis, planum temporale/parietal operculum, anterior cingulate gyrus, insular cortex, and Heschl’s gyrus; bilateral thalami and precuneus; the left parahippocampal gyrus, and lateral occipital cortex.

The results highlight an asymmetric effect of sex on the developing brain. Amber Ruigrok, who carried out the study as part of her PhD, said: “For the first time we can look across the vast literature and confirm that brain size and structure are different in males and females. We should no longer ignore sex in , especially when investigating psychiatric conditions that are more prevalent in either males or females.”

    ‘Reviewing 20 years of research’. This suggests to me that these difference have been known for what, 20 years?

    The ‘progressive’ left actively denies reality. Facts are irrelevant.

    Will we stop pushing girls into math? No. This will be a call to arms to prove nature wrong.

        Borat had some hilarious moments. Among the many, I found the part where Borat and Azamat escaped from the old Jewish couples’ bed and breakfast by throwing dollar bills at the two roaches they thought were polymorphed Jews while they crawled out the window…

    Now it’s just about inevitable that I have to surrender to my male overlords! *Joking*

    I love this kind of information, because it just proves that we’re sooooo equal!

      Enjoy. I’ll enjoy watching.

        You gotta be into that kind of stuff if you fight with those feminazis.

        Do you care for roasted or fried eyes and tongues?

        I can make ‘em for you in my kitchen…..

        • NeanderthalDNA

          Their vitriol is actually very demeaning to women. I personally believe in merit and free will. If a woman is qualified and wants to play with the boys…more power to her. Women DO bring valuable specific tools and perspectives to most endeavors. If a woman prefers a more traditional role…fine. Tried and true. If a man cannot admit he owes his success to a virtuous and strong woman he’s a silly man indeed.

          But the feminazi is not a real woman. She’s a spiteful, antinomian harpy, a tyrannous ideologue who hates only men and God more than her “treacherous sisters” who prefer something different and are happy.

          Malcontents love company.

            “If a woman prefers a more traditional role…fine. Tried and true. If a man cannot admit he owes his success to a virtuous and strong woman he’s a silly man indeed.”

            I am more obsessed with the demographic war that is waged against our race than with our so-called women’s rights which we will lose anyways if we do make an effort to become victorious in that demograhic war. I will always trust White men the most, therefore I am willing to fight for them in my way. Women can do tricks that men cannot, like getting pregnant and bearing babies. Since we can do such things that men cannot, we are chiefs in this demographic war. Men can do their scientific stuff and so on to win the war in those fields, and we need to accept our responsibility and start fighting against anti-Whites demographically. Anti-Whites will stand no chance against “traditional fanatics” in the long run, because we will simply outbreed them mercilessly and take demographic revenge with our fanatically high fertility rate. What’s the problem with fanaticism when it’s just more successful?

            Whites have been in the defensive mode for too long. We need to try the offensive mode. We need to start taking the initiative in this demographic war that is being waged against us. We need to accept that we have been the victims of cruel injustice and that we have suffered for far too long, so that we know that it is our duty to survive, procreate and win.

            I’m going to bed now, because it’s late in Germany. See ya.

          • Brian

            A friend of mine had a great-aunt who was one of the first prominent female architects in the southern US. She faced a lot of skepticism and was locked out of high-paying, high-prestige commercial work, so she focused on houses. And she did outstanding work in that field. We need to allow for the talent to rise, wherever it comes from, but not to engage in procrustean affirmative action. If this leads to merit-based, unequal outcomes, so be it.

        • Peter Connor

          Wombats from hell aren’t in it.

    • Extropico

      We are equal in value. Thank you for being a mother.

    • jeffaral

      Yes, Heidi, you should be thankful that we males magnanimously allow a few females to post comments on this site.

    • Brian

      This wasn’t emphasized here, but other studies have shown that when doing intellectual tasks under MRI scan, the male brain is much more localized– one or two areas will be fiercely active, and the rest not…which areas depends on the type of task. The female brain is more decentralized, or holistic, more networked or ‘general-purpose/well-rounded’. You get an MRI glow more evenly distributed instead of the hotspots.

      So this might explain why 14-y-o boys and girls have about the same average score on math tests, but the distribution is narrower for girls– they tend to clump around the middle, while boys dominate at both ends– the worst and best math students are more likely to be boys. It could also explain how men are more likely to be geniuses, but also schizophrenic, stutterers, autistic, psychopaths, or violent criminals… men are ‘spiky’, and women are ‘smooth’ in terms of brain function.

      • NeanderthalDNA

        That makes a lot of sense. Women seem to be better multi-taskers. Also are good at holistic memory.

        One experiment had males and females sit in an office alone for several minutes, waiting to be interviewed for an experiment. The experiment, however, was how much and what they remembered from sitting in an office for a few minutes alone. Women were better able to describe in detail the minutiae of the office, almost a photographic, holistic snapshot, as if their brains had captured the totality of the experience.

        Men, were found to be lass capable of paying attention to multiple simultaneous stimuli, but obversely better able to “tune out” distractions – possibly the source of many a woman’s ire at trying to talk to her mate while he watches something on TV, and of course the male’s ire at being expected to pay close attention to more than one stimulus at a time.

        • Brian

          Yes, the multi-tasking is real. You ask a woman what she’s thinking and she might mention 4-5 things. A man will say 1-2. This could also explain ‘women’s intuition’– all parts of their brain parallel processing to form a quick overall gut feeling about something. And it might explain why women are generally better at foreign language acquisition– that’s something that requires distributed thinking involving a lot of areas. The flip side is that men would be better at something like chess playing, requiring a singular focus.

          • NeanderthalDNA

            That makes sense. I hated teaching Spanish by purely W

          • Brian

            Funny… I had the same method of learning French– favoring formal instruction of grammar rules and vocab– structural approach. The women in the classes seemed to favor ‘throw me in the pond and let me swim around in it’ approaches. Or you could say they wanted to date it, whereas I wanted to take apart the engine and look at the various parts.

          • NeanderthalDNA

            Yes. This is why…

            1. Sometimes, especially when the hormones start flowing…better to teach males and females separately, and…

            2. Lack of recognition of DIFFERENCES is bad for teaching. By the time I left it was all the “whole language” thing, which irritated me (and was easier to dumb down to simple phrase teaching, never enough time to truly “immerse” the student in standard HS setting).

            Yeah, I saw the invisible machine of the language and once I learned how it all fit together and had enough understanding of the workings of the different parts…then I could sort of…feel it.

          • Brian

            Gender-segregated classrooms are a good idea I think, at least through high school, esp. when the teacher is the same gender as the students.

          • NeanderthalDNA

            Very wise observation. The opposite sex is often just another distraction, especially so for a certain ethnicity, but really for all. Boys need to concentrate and girls need to not be harassed by hormone raging boys…

            And then there’s the pervert teacher factor, which is really very rare, but when it does happen, especially when the perv is a hot young blonde woman…

            Jeez. Also very young teachers just out of college should not be teaching 16-19 year olds…nature…

            Thank God I’m a real Southern man, good at politely deflecting such advances without hurting feelings. I usually put any females that took a fancy to me to work grading papers and filing stuff and making my classroom pretty and such, lol…

            But I always had a very low opinion of supposed adults who took advantage of things like that. Amazing.

            I did run into a FORMER student of mine like three years after she graduated once, who had a crush on me as my student. I’ll not comment on that, being a gentleman, lol, but that’s a different situation…

            You in the “Hot”lanta region? Man it’s frozen around here (Cola, SC).

          • Brian

            I hear all the time about these 24-y-o lady teachers getting with 17-y-o boys. Ehhhh, I don’t think that happened much with us back in the 80’s, at least not to make the news. My first grade teacher was 23, but all the others I can remember were at least 30, and many 40’s or 50’s. Having only a 6-year age gap, and opposite genders makes about as much sense as having female guards in a male prison, or vice versa.

            Yes, Atlanta– looking to move up to the GA mountains where my folks came from in days of yore, to ‘de-diversify my portfolio’. But have to spend a couple more years down in Occupied Territory to get the $. If you’re down in ATL send me a message and I’ll see if I can hook you up with some ‘mountain dew’ of questionable legality. ;-)

          The other day, my brother didn’t believe me when I said I had just learned how a thermostat works (I am a ridiculously nerdy girl). It seemed to me surprising that more than a few laymen *do*. On a bike, I know the pedals make some gears turn which make the wheels turn, but *draw* one…?

          • Brian

            You know about the gear ratios and torque vs. linear/rotational speed?

          • Andy

            Haha, no. I have an idea of what those terms mean from high school physics. :)

          • Brian

            Well if you pedal a big gear with 100 teeth, and it’s attached via chain to a smaller back gear with 50 teeth, the back gear will have to spin twice for each revolution of the pedaled big gear, so it spins twice as fast as what you’re pedaling, but it will have half the rotational force (torque) on it– useful for high cruising speeds.

            If you’re going up a hill though, you’d want a larger rear gear, so the wheel attached to it spins more slowly but has more torque on it.

            In our era of high gas prices and being cognizant of fuel economy, I’m wondering why the CVT hasn’t taken off.

    Slightly off topic, but I saw a news segment a few days ago about a decades long study on dosing amounts of medicines given to men and women. Usually, men and women are given the same dosage of medication which is a fatal flaw according to the scientists conducting these studies. For example, the sleep aid Ambien is given in equal amounts to both sexes, often resulting in death for the female. That’s just one of many examples, and they claim ALL medications on the market need to be reevaluated for gender, but will never happen because of the cost. I’ll never understand why people can’t accept there are very real differences between the sexes. We are not equal, and even small children know this is true.

    • LovelyNordicHeidi

      “often resulting in death for the female”

      That’s why we need to embrace inequality. I don’t want to die because some libtard refuses to acknowledge the obvious differences between males and females.

    • sbuffalonative

      Because if we admit there are differences, the next step is death camps. At least that’s how the narrative goes.

  • MekongDelta69

    Once again – ANOTHER useless study on a subject about which everybody with an IQ of low double-digits has known the inanely obvious forever.

    It must be great to get paid big bucks to do useless ‘studies.’ I call it, ‘academic welfare.’

    • bigone4u

      Yep. Profs reinvent the wheel and get paid big bucks to do it.

      • Brian

        To the extent that some stubbornly refuse to see that that wheel has indeed been invented, these ‘proofs of the obvious’ can still be useful. Putnam’s ‘Bowling Alone’ idea that diversity and community are antagonistic seems obvious, but it helps to have the authority and careful number-crunching to back up the ‘obvious’ for those who need it.

  • bigone4u

    Does this study show why women in clubs are incapable of going to the bathroom alone? Does it show why women can name hundreds of colors while men can name only a dozen? Does it explain hypergamy by women? Why do men love the Three Stooges and women hate them? Women differ from men and all the feminist bull isn’t going to change it.

    • Spartacus

      • bigone4u

        Yes, but only women can see them. Women have these magical powers that men don’t have. At least, that’s what a feminist told me.

        • ncpride

          Then she is an idiot. It’s scientific fact colorblindness is overwhelmingly a male trait, pretty rare in women. But as per usual, loony liberals or rabid feminists don’t let science get in the way of their delusions.

          • Alexandra1973

            But then they accuse Christians of ignoring science, go figure.

            Science and Christianity are not necessarily mutually exclusive. Now junk science, that’s another story.

        • Rhialto

          Women do have much better color vision than men. Evolutionary biology provides the reason. Humans for millions of years were hunter-gatherers. Men did the hunting, and women did the gathering. Gathering requires the ability to distinguish ripe from unripe, for which color is the best guide. Hence women who had better color vision could gather the most nutritious vegetation. Good color vision thus became a significant survival trait in women.

          Since it is not necessary in men, apparently there is an advantage the genetics for good color vision being expressed only in females.

          • Anna Tree

            There are actually some women who have 4 cones and therefore can see millions of additional colors especially in the reds (usually people can see one million). Those women though give birth to colorblind boys, so that is maybe not the best…

        Perhaps they mean shades and tints of colors.

  • Rhialto

    I read some years ago that the main difference in male/female average brain size is that men have ~100 cc extra brain tissue dedicated to geolocation. This reflects the environment in which modern humans evolved: females stayed close to the village; men often went long distances to hunt and fight. Since brain tissue is expensive to grow and maintain, women had a survival advantage in not having this unnecessary brain tissue.

    • Alexandra1973

      I’m a gender realist as well as a race realist, I might add.

      • ncpride

        I will readily admit, I’m utterly useless when it comes to direction. When going alone somewhere I’ve never been before, the hubby knows darn good and well not to tell me to go southbound on I-50 until I get to so and so road. No, when giving me directions when he can’t accompany me, he knows he must give me familiar landmarks, how many stoplights to go through, how many roads I’ll pass before I get to the one I need and so forth. I’m such a…. girl in that respect!

        • Ella

          My husband has no sense of direction so I navigated him through major cities and parks around the world. He can get lost on an island somehow and probably panic.

          • ncpride

            My sister has no problem with direction either, but me…? One wrong turn and I’m completely lost. My husband can find his way around any place like you, so I hate going to unfamiliar places without him. When it comes to directions, I draw a blank for some reason!

        • Alexandra1973

          If you try to *tell* me directions it’s more likely I’ll get turned around. If I see it on paper, then there’s no problem.

        It doesn’t say the women’s brains are inferior, just different. Which everyone has known forever, but has had to keep silent about for the last 40 years because the inmates have been running the asylum.

        • Alexandra1973

          Oh, I know that.

          Like a typical female, I tend to do better in languages. In fact I find studying how languages evolved to be fascinating. In the 12th grade I had Spanish AND French, did well in both of them. I took French for kicks, since I had a class slot open, and Spanish I’d had since 7th grade. I did well in English, and I was able to read at the age of 3 (Head Start was a bit superfluous here).

          I don’t know how atypical I am here, but I can do pretty well in math. I went up to intermediate algebra, but I got sick of math, and since my high school only required 2 years, after the 10th grade, no more math for me. I can *do* it but I’m not that interested. Chemistry would have been more interesting had it not been for a sarcastic teacher and clashing personalities.

          I also like arts, and have knitted and crocheted hats and mittens for myself and my son. I was in the marching band in high school, and I was able to read music at the age of 4.

          • ncpride

            You sound like a carbon copy of my daughter. She loves languages, and dabbles in quite a few, German being her favorite. She does really well in math and loves chemistry, too. She’s been in concert and marching band for seven years now, and she can draw or sketch anything you put in front of her. At the risk of tooting my own horn here, she really is quite a remarkable young woman, and nothing like the typical teenager of today. (Thank God!)

          • MBlanc46

            My understanding of the difference in intelligence between men and women is the male tendency to excel in spatial and analytical tasks and the female tendency to excel in linguistic tasks. In addition, women cluster closer around the mean in IQ, while men are more distributed along the bell curve. The most intelligent person who ever lived was almost certainly male, as was the stupidest.

        • BonV.Vant

          For the past 40 years anything that smelled of maleness or masculinity has been demonized. WE have been told for the last 40 years that females are superior. So, we end up getting women in government and we end up getting a woman telling us that we have to pass obammacare to find out what is in it. This sort of thing would never have been possible in a male dominated world. Men in power would do things and say things that women find unacceptable. Any time one has a strong position and is uncompromising and is willing to fight for it, women dislike it. Women are all about getting along, being nice. Men are warriors.

        I’m not sure maps are relevant to the debate. Maps as we know them today did not exist in the paleolithic. Stone agers most likely got around using landmarks.

      • BonV.Vant

        reading maps is not really a spatial skill. Women have very poor spatial skills.

    I often use the gender difference in IQ to open the discussion about the race difference in IQ… It goes like that:

    “Women evolved differently than men: their activities were
    different so it seems to me logic that their bodies through natural
    selection evolved differently! It is naive for me to think that women
    are different in the outside but the same than men in the inside.

    Not
    only because of the difference in body size but also in the difference
    of use. A man’s heart is 25% bigger, because it pumps blood in general
    in longer distance than a woman’s heart and thus, for any given work
    rate, the faster heart rate means that most women will become fatigued
    sooner than men. Women have less bone mass than men, but their pelvic
    structure is wider. This difference gives men an advantage in running
    efficiency. Men have 50% greater total muscle mass, based on weight,
    than do women and a woman who is the same size as her male counterpart
    is generally only 80% as strong.

    So men usually have an
    advantage in strength, speed, and power over women. No surprise, men
    hunted and were hunted while the women stayed in the cave or camp
    whatever and gathered berries and roots or tend to the children and
    therefore not only the body developed differently but brains did too,
    Edward O. Wilson, of Harvard University, said that human females tend to
    be higher than males in empathy, verbal skills, social skills and
    security-seeking, among other things, while men tend to be higher in
    independence, dominance, spatial and mathematical skills, rank-related
    aggression, and other characteristics. Please websearch Renato Sabbatini
    “Are There Differences between the Brains of Males and Females?” and
    articles on Richard Lynn’s studies in BBC and dailymail websites.

    Why should it be different with races? We are different in the outside, why wouldn’t be differences in the
    inside too? Races too have evolved differently, I would say even more
    because of separation
    and the very different environment. Our bodies, including brains, have nothing magical about them, they have a physical/biological base like everything else in existence.”

    Then I hit them with Rushton, Murray and more.

    I thought women had more white matter and men had more grey matter, but this article contradicts that. Here is a quote from another article you can look up:

    In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men. Gray matter represents information processing centers in the brain, and white matter represents the networking of – or connections between – these processing centers.

    • sshadow

      I have seen that quote also. It must be an error. White matter is the myelinated fibers, which is the wiring, not the processor. Someone was confused when they said this quote. Men have more gray matter so can process more data. Maybe math and spatial relations require more data points to process. Of course men have more white matter than women if they have more gray matter. Gray matter is the main processing body, and white matter is the wire leading out from that processing body. Who is likely to have more gray matter, Charles Krauthammer or Joy Behar?

      • Hal K

        According to Wikipedia, white matter coordinates communication between different brain regions, so it is more than just wiring.

        I don’t know what to make of all this. The statements about white and grey matter I quoted get thousands of hits on Google.

  • Anna Tree

    But when will we read:
    For the first time we can look across the vast literature and confirm that brain size and structure are different in RACES. We should no longer ignore RACE in neuroscience research, especially when investigating psychiatric conditions that are more prevalent in certain RACES.

  • Aaron997

    A few years ago, the politically-correct crowd changed their stance on whether or not men and women have mental differences, if for no reason other than for transgender issues.

    Seeing them backpedaling has been HILARIOUS.

    • BonV.Vant

      They fired a professor at Harvard for saying men were better at some things, such as math.

  • Lee_CPA

    Bottom line: Men haven’t understood women and never will. LOL

    • Einsatzgrenadier

      Nonsense. Anyone with a rudimentary grasp of evolutionary theory will quickly discover that women are considerably less complicated than men and, as a result, very easy to understand. For example, if you’re handsome and/or rich, you will never have any problems with the female of the species.

      • Ella

        Having wealth has to do with providing better opportunities for off spring like safer neighbourhoods and education for later success. Women also want men to display maturity and stability for nesting. On the other-hand, men want attractive women as they can get for their selection. Both women and men still desire caring partners. You can criticize women all you want but these practices have lasted thousand of years -resources and mating.

    • BonV.Vant

      bottom line, women don’t understand themselves and never will

  • Sangraal

    I was actually being sarcastic. I don’t shy away from the JQ, but the idea that anything and everything that any and all of them do has an agenda is absurd.
    Having said that, I’m not particuarly eager to leap to their defence.

  • Hal K

    Yes, but if these statements about brain size don’t apply to intelligence then we have to take them with a grain of salt.

  • WR_the_realist

    That men and women are the same in their mental functioning is one of those ideas so obviously insane that only highly educated people could ever believe it.

  • Shawn_thefemale

    There are generalities and there are exceptions. Men are generally better mechanics for example, but there is occasionally a female that can whip his butt in a mechanical sort of way. Women generally do the cooking yet there are male chefs who can run circles around them. Men and women ARE different and were intended to be. They compliment each other, challenge each other, keep each other within the bounds of civilized society (most of the time). I LIKE men opening doors for me – I will also hold the door for men behind me. I don”t want to be male – I’d make a lousy one. But I am one heck of a capable, intelligent, independent, logical female and make a fabulous partner to my husband (as he does me) because we ARE different. I will pick up dead mice if I have to, but if he’s around, no thank you. We all have our individual strengths and weaknesses, and when combined with the differences between men and women things can get very interesting. Thank God.

  • NeanderthalDNA

    William James was not Jewish. Neither was BF Skinner, nor Watson.

  • NeanderthalDNA

    I suppose you are referring to Freud, who did not found psychology/psychiatry, and whose ruminations have since been largely discredited by real scientific research and process.

    If you want real, good, COGNITIVE psychology just dig back some 2600 years and look at the non-metaphysical side of Buddhism.

    Never better thought out, in my opinion…nor in the opinion of William James either.

  • NeanderthalDNA

    Yeah, some men think more like women and vice versa, not necessarily homosexuals, either.

    The autism thing is interesting. I dated a very bright young woman years ago who was almost a dyslexic mushmouth, verbally, but VERY sharp mathematically and scientifically. I regularly “helped” her write papers…

    Very attractive in a weird way…

  • LHathaway

    there aren’t too many people who want to exterminate white women in this world. . . maybe black women, and white men. . well, you got a point. Even so. . it would take them banding together. . . well you’re right. . the public should never find out about race and sex differences. . . (sarcasm off).

  • LHathaway

    Surely this is not really true. It’s posted in a newspaper isn’t it? This is more blatant misinfomation and disinformation and is surely closer to the opposite of the truth.

    Lefties will decide that white men are victims, too, one day. Even if it kills them.

  • Ella

    Jews marrying exogenous has increased to 40% just in the last 50 years so the effects on IQ has not revealed itself. Before the 1900’s in Europe, rates were only 5-15% for heterogeneous marriages. Most Rabbi’s would not approve marriage to a gentile. Around 1900’s Jews married outside when there were shortages of women in general and also, for gentile women, these “women were seen as marrying out of their ethnic groups in order to rise in the stratification system or to “marry up” by trading beauty for social position.” So, it was money and societal status,

  • Dutch

    What the difference is i do not know, probably a lot. Can you be trusted, that’s importand.
    Stay very close to the truth, if you don’t , you’re not that intelligent.

  • Brian

    Well said.

  • Truth Teller

    Why should I feel inferior to Asians or Ashkenazim in general when I personally have a higher IQ than both of their averages?

    • Anonymous

      You should not feel inferior to them as an individual, because your personal IQ is higher. But you should also not feel that your group is better than their group because their group average is higher than your group average.

      • Truth Teller

        Why should I be tied town to any statistics to any particular group? Besides, even within countries IQs and levels of achievement can vary. If so, explain why Brahmins in India outperform the rest or Christians in the Levant outperform the other religions? My group is personally my family. If you come from a higher IQ family than the average, you can say that you do feel superior.

  • Truth Teller

    Actually they do have strong family ties and cooperate a lot. You must be talking about Northern and Western European families, not families like the more recently coming Sicilians or Greeks.
