HELLO FRIENDS,

On my last science research, I did a research on Facts About the Eagle. You can read that post here.

Today I am going to be sharing a research I did about the human brain of both the male and female.

Do you ever ask yourself, why does a man act the way he acts and why do a woman behaves the way she behaves?
Through this research work, I will be sharing some of the things I have learnt during my research.

The Question is do the anatomical differences between men and women—sex organs, facial hair, and the like—extend to our brains? The question has been as difficult to answer as it has been controversial. Now, the largest brain-imaging study of its kind indeed finds some sex-specific patterns, but overall more similarities than differences. The work raises new questions about how brain differences between the sexes may influence intelligence and behaviour.

For decades, brain scientists have noticed that on average, male brains tend to have slightly higher total brain volume than female ones, even when corrected for males’ larger average body size. But it has proved notoriously tricky to pin down exactly which substructures within the brain are more or less voluminous. Most studies have looked at relatively small sample sizes—typically fewer than 100 brains—making large-scale conclusions impossible.

Findings suggest that human evolution has created two different types of brains designed for equally intelligent behaviour.Male and female brains show anatomical, functional and biochemical differences throughout life.

For example, I found that women tended to have significantly thicker cortices than men. Thicker cortices have been associated with higher scores on a variety of cognitive and general intelligence tests.Meanwhile, men had higher brain volumes than women in every subcortical region they looked at, including the hippocampus (which plays broad roles in memory and spatial awareness), the amygdala (emotions, memory, and decision-making), striatum (learning, inhibition, and reward-processing), and thalamus (processing and relaying sensory information to other parts of the brain).source.

There is a lot of data already out there on the subject of male and female brains. However, the media coverage this study received implies that there is a great deal of public interest in knowing about the real differences between the brains of men and women. So what follows is a basic rundown of the more definite differences between the brains of men and women.

GENETICS

Male and female brains actually differ right down at the genetic level in quite a drastic way. Studies reveal that typically EVERY CELL in the male brain contains a Y chromosome. Quite alarmingly, female brains usually contain no Y chromosomes at all! This lack of a Y chromosome has many obvious physical effects, but most women still manage to lead normal, cognitively-unimpaired lives despite this clear deficit in the very DNA of their brains. Research into how they manage this is ongoing. source

LOCATION

One startling difference between male and female brains is where they are found. It may surprise many, but male brains are found almost exclusively inside male skulls, whereas female brains are found only inside female skulls! Such an extreme bias in brain-skull association can’t possibly be due to coincidence. The fact that male and female skulls are also different and perfectly sized to house their associated brains is even more unlikely.source

SIZE

As previously mentioned, there is an established size difference between male and female brains. Male brains tend to be bigger overall than female ones. This is also true for male legs, torsos and skeletons in general. Human men generally tend to be bigger than women, and this is reflected in brain size. Some argue that this means men are more intelligent than women. Using that same logic, human beings are intellectually inferior to elephants and sperm whales. Certain people may scoff at this very notion. “You never see elephants or sperm whales queuing for the latest version of the iPhone!” the might say, which probably doesn’t prove the point they think it does. Sperm whales and elephants also never publicly criticise statements made by figments of their imagination, so they’re doing well overall.

CONNECTIONS

Male and female brains differ in the connections they form. Most notably, the male brain is generally connected to a penis by various involved systems. The female brain lacks this connection and is instead linked to a vagina via a complex system of associations. The male brain-penis association seems to be more straightforward than the female brain-vagina one, but that may be due to the fact that the latter has a lot more bilge written about it.

PAIN SENSATION

It is generally believed that the male brain is better able to tolerate pain than the female one. However, the female brain is able to raise tolerance to pain when engaging in the process of ejecting a human from the pelvic regions. Thus far, no male brain has ever been recorded doing this.

SPECIALISATION

Observational studies have shown that the male brain is hardwired to be paid more, occupy more powerful roles and positions, and be more inclined to kill things randomly, whereas the female brain is hardwired to get more harassment and oppression, develop worrying obsessions with physical appearance and to care more about other humans and sometimes kittens.

Or, and this may seem controversial to many but it’s worth considering, it could be that the human brain develops in accordance to what it experiences, and things it experiences and is made to do more often are reflected in the sorts of connections that develop. This would suggest that there aren’t actually any marked differences between male and female brains. However, this would mean that there is no scientific basis for all of our stereotypes and prejudices about what certain sexes should/shouldn’t do and they all stem from irrational or unpleasant cultural influences that haven’t gone away yet, forcing us to admit to ourselves that our preconceived notions about certain sexes or genders are just self-fulfilling clichés with no logical basis, potentially threatening our beliefs, our positions and even our identity.

Some Facts About The Male and Female Brain

  1. Women are the only ones in their right minds.

Studies show that men mostly use their brain’s left hemisphere to process information, while women are more skilled at using both hemispheres. This would literally mean that women are the only ones in their right minds!

  1. Males have bigger brains—which doesn’t mean they’re smarter.

On average, guy brains are about 10 percent larger than gal brains. But this is probably because on average, guys are 10 percent larger than gals. Although males tend to do slightly better in math while females do slightly better with language, standardized intelligence tests show no statistically significant difference between males and females.

  1. The male brain is geared slightly more toward math.

Males tend to have much larger inferior-parietal lobules (IPL) than females. This area of the brain is thought to influence mathematical ability. The brain areas that are thought to control math and geometry skills mature in boys about four years earlier than in girls.

  1. The female brain is geared slightly more toward language.

The frontal and temporal areas of the cortex are larger in females than in males. These brain areas are thought to influence language skills; they mature in girls about six years earlier than in boys.

  1. Women are more emotional, but we all knew that already.

Females have a larger hippocampus and a deeper limbic system than males, which allows them to feel the full range and depth of the emotional spectrum far more than those coldhearted, unfeeling jerk guys.

  1. Women feel more pain, but we all knew that already, too.

Upon experiencing pain, men’s right amygdala is activated, while it’s the left amygdala in women. Since the left amygdala is more closely associated with “internal functions,” it is thought that this is why women experience pain more acutely than men do.

  1. Men tend to have better spatial abilities.

Men have a thinner parietal region of the brain than women, which makes it easier for them to visualize rotating 3D objects—assuming that’s your idea of a good time.

  1. Men are more likely to suffer from neurological disorders.

Males are more likely to be dyslexic and autistic than females. They are also more likely to suffer from ADHD and Tourette’s Syndrome.

  1. Women are more likely to suffer from mood disorders.

Male brains synthesize serotonin far more quickly than female brains, which may explain why women are far more prone to depression. Women are also far more likely to suffer from posttraumatic stress disorder after a traumatizing event.

  1. Male and female fetuses start showing brain differences at around 26 weeks.

At around the 26-week stage, girl fetuses generally start developing a thicker corpus callosum—the part of the brain that connects the left and right hemispheres—than boy fetuses. This may help explain the fact that women tend to use both hemispheres of the brain while men lean toward the left hemisphere.

  1. ###When it comes to intelligence, there are more male than female outliers.
    Male IQ has greater variance than female IQ; in other words, while females cluster toward the middle, more males occupy the extreme high and low ends on the intelligence scale.

  2. Women handle stress better than men.

Both males and females release the hormone oxytocin during stressful events. But female estrogen combines with oxytocin to produce a calming effect, whereas male testosterone only makes men more aggro.

  1. Men have weaker impulse control.

The brain areas that control aggression and anger are larger in women than in men, which may account for some degree in larger male rates of violence.
