Why Are People’s Brains Different Sizes

How much does a Brain Weigh? || KnowledgOPedia||

There are many tactics people use to end arguments and confrontations, most of them having to do with size. Parents, for example, seem to favor “Because I said so” as a way to put a stop to a disagreement with their children, who, after all, are much smaller than they are for at least a little while. School bullies have the reputation of being big kids, their stature all the more advantageous for stuffing the wimpy geeks down the toilet. And let’s say that a couple is arguing about the best way to get to their destination; conceivably, the man could end the argument by saying, “Of course, I’m right! Males have bigger brains.”

Men do in fact have bigger brains than women. The average human brain weighs in at 2.7 pounds, or 1,200 grams, which is about 2 percent of our body weight . Males, though, have about a 100 g advantage after accounting for differences in total body weight .

Which brings us to the age-old question: Does size really matter? That is, does the male in this scenario have any sort of valid point when he claims to be smarter with his bigger brain? On first glance, one might think so, because the way that we humans differentiate ourselves from our earlier primate ancestors is by our bigger brains. But if bigger is better, does that mean we are only slightly smarter than a walrus, which has a brain weighing 2.4 pounds , and much dumber than a sperm whale, which has a whopping 17-pound brain ?

The Visual Areas Of The Brain Are In The Back

The part of your brain responsible for vision, the occipital lobe, is located in the back. This is why if you get banged in the back of your head, you will see stars. The left side of your brain controls the vision on your right side, and vise versa. Your brain also processes sound on the opposite sides of the head.

What Can Happen When Brain Processes Malfunction

When brain chemicals malfunction it can lead to a host of problems, including mental illness, tremors, and symptoms related to Parkinson’s disease, among other issues. In our brains, there are chemical and electrical processes that allow the brain to communicate with the nervous system. Neurotransmitters are nerve-signaling chemicals that send messages between neurons that use electrical signals to pass along information. When the chemical processes of neurotransmitters malfunction, mental illness such as depression, anxiety, and other mood disorders can occur. When the electrical signals don’t work properly, it can lead to tremors, seizures or Parkinson’s disease symptoms, and other motor system disorders.

The Size Of The Human Brain

  • In terms of weight, the average adult human brain weighs in at 1300 to 1400 grams or around 3 pounds.
  • In terms of length, the average brain is around 15 centimeters long.
  • For comparison, a newborn human baby’s brain weighs approximately 350 to 400 grams or three-quarters of a pound.
  • Men tend to have bigger brains than women. After taking overall body weight into account, men’s brains tend to be approximately 100 grams larger than women’s.
  • In women, parts of the frontal lobe and limbic cortex tend to be bigger than those of men.
  • In men, the parietal cortex and amygdala tend to be larger than those in women.
  • Neurons are the structures that serve as building blocks of the brain and nervous system. They transmit and carry information, allowing different parts of the brain to communicate with one another as well as allowing the brain to communicate with various parts of the body. Researchers currently estimate that there are around 86 billion neurons in the human brain.

The Brain Goes To Sleep When We Do

Weight Of Human Brain

When we sleep, our brain is very active, and dreams occur. The difference between being awake and being asleep depends on which brain systems are activated at a given time. Chemicals in the brain called neurotransmitters act on different nerve cells in the brain, telling the brain to fall asleep as well as communicating which parts will remain active while we sleep.Sleep is also critical for brain functions that we use when we are awake, such as memory, concentration, coordination, creativity, and well-being. A good night’s sleep can strengthen all these areas. Without adequate sleep, people often have difficulty functioning.

Developmental Changes In Brain Morphology

Brain weight reaches adult values between 10 and 12;years of age. The fastest growth occurs during the first 3;years of life so that by the age of 5;years the infant’s brain weighs about 90% of the adult value . Although the brain continues to change throughout life, changes in brain morphology during childhood and adolescence are more subtle than those in the first 4;years of life.

Paralleling morphological brain maturation are biochemical changes characterized by an increase in N-acetyl-aspartate and creatine, and a concomitant decrease in choline, myoinositol, and lipids . The choline peak includes free choline, glycerophosphorylcholine, and phosphorylcholine. It represents the high levels of substrate needed for the formation of cell membranes, with gradual reduction as soon as incorporation of lipids has taken place. NAA is considered as a neuronal marker and is also expressed in immature and mature oligodendrocytes. Therefore, NAA also reflects oligodendrocyte proliferation and differentiation . As neuronal cell density in cortex decreases with dendritic maturation, the increase in NAA with age reflects a contribution from non-neuronal origins.

Human Head And Brain Size

Blue Sky Science: How much does a human brain typically weigh?

The human head contains 22 bones, consisting the cranium and the facial bones. The cranium is formed by 8 bones: the frontal bone, two parietal bones, two temporal bones, the occipital bone in the back, the ethmoid bone behind the nose, and the sphenoid bone.

The face consists of 14 bones including the maxilla and mandible .

The cranium protects the brain, which, for an average adult male weighs about 1400 gram . The brain of Russian novelist Turgenev, weighed 2021g , Bismarcks brain weighed 1807g , while that of famous French statesman Gambetta was 1294g .

Einsteins brain weighed 1230 gram , meaning Einsteins brain was smaller than average.

Female average brain mass is slightly less than that of males. The largest womans brain recorded weighed 1742g .

Human brain vs animal brain

An elephants brain weighs 5000g , a whales 10000g . In proportion to the body, the whale has a much smaller brain than man. This seem to give man the edge, until it was discovered that the dwarf monkey has 1g of brain per 27g of body, and the capuchin monkey has 1g of brain per 17,5g body, whereas man has 1 gram of brain to 44g of body.

Brain power

The human brains consists of more than 100 billion neurons through which the brains commands are sent in the form of electric pulses. These pulses travel at more than 400 km/h , creating enough electricity to power a light bulb. The brain consumes more energy than any other organ, burning up a whopping 20% of the food we take in.

  • How Many Brain Cells Does A Human Have

    The human brain contains about 86 billion nerve cells called “gray matter,” according to a 2012 study published in the Proceedings of the National Academy of Sciences. The brain also has about the same number of non-neuronal cells, such as the oligodendrocytes that insulate neuronal axons with a myelin sheath. This gives axons a white appearance, and so these axons are called the brain’s “white matter.”;

    Cholesterol Is Key To Learning And Memory

    How Much Does The Human Brain Weigh?

    The brain has a higher cholesterol content than any other organ.; In fact, about 25% of the bodys cholesterol resides within the brain. The brain is highly dependent on cholesterol, but its cholesterol metabolism is unique. Because the blood-brain barrier prevents brain cells from taking up cholesterol from the blood, the brain must produce its own cholesterol. The brains cholesterol is much more stable than the cholesterol in other organs, but when it breaks down, it is recycled into new cholesterol right in the brain.

    Relationship Between Child Birth Weight And Brain Weight

    One of the initial things that occur in hospitals is that newborn children are weighed. Birth weight is an important factor in the health of an infant. It signals how things were in the mothers womb and how the child will develop. Factors such as low-birth weight and premature births can affect the development of a childs brain afterward. In the case of low birth weight, most hospitals will put in place other measures to supervise the development of the baby. Babies that weight lower than 2500 grams are considered low birth weight.

    Birth weight affects both the brains total volume and the extent of the cerebral cortex in the later years of a child. Therefore, birth weight can be used to determine future characteristics and development of the brain. Additionally, children that are born underweight are susceptible to various mental conditions compared to their healthy counterparts. One such disorder is Schizophrenia.

    How Much Did The Heaviest Human Brain Recorded Weigh

    Are The Species With The Largest Brain Size Smarter

    If you compare the brains of some species, you will realize that those with higher brain capacities have higher cognitive abilities.

    For example, the brains of mammals – such as primates or felines – are larger than those of insectivores and have higher cognitive abilities.

    However, this relationship is not always so. For example, the brains of cows are larger than that of any species of monkey, but they are not so intelligent.

    A much more obvious comparison is that of the human brain and that of the elephant.

    The brain of the elephant weighs on average 4700 grams in comparison with the 1400 of the human being.

    Also, the brain of the sperm whale weighs 7800 grams.

    Evidently neither sperm whales nor elephants are cognitively superior to humans.
