What are some of the innate defects in the human brain?

<> there is no perfect thing in the world, yes, human beings rule the whole earth, but we are not perfect products, our core - the brain, is a product with a lot of bugs, for example, the brain itself is soft and too fragile, although it is protected by the skull, it is still very vulnerable to physical trauma, a slight brain ** is already very uncomfortable, and a serious injury may be directly disabling or fatal. I used to think that if the brain and spinal cord were all turned into bones, then it would be hard to get hurt! But now it seems that if the nerve cells are bone, there may be several problems, the nerve signaling efficiency becomes low, the most agile people are similar to today's dementia patients, the spine should not be as flexible as it is now, and the activity is greatly limited, because the brain has become solid, basically can not be buffered, can only be hard to resist, knocking is similar to knocking triangle, the whole brain is vibrating, unable to think.

These assumptions may not be perfect, but in short, the brain is fragile, so don't forget to wear a helmet if necessary to reduce the risk? Attention can be distracted, and the brain itself can multitask at the same time, not as some people call "single thread", but after attention is distracted, your efficiency will definitely decrease. A very familiar example, that is, driving to pick up **, will cause the driver to reduce the attention to the road situation, prone to accidents, of course, the characteristics of the brain are far more than these, such as addiction mechanisms, illusions and hallucinations, may cause a certain negative impact in life, but everything has its own limitations, the brain is no exception, I will continue to add when I have time!

Nothing is inherently perfect, and although the brain is a symbol of human near-perfection, it can still be flawed.

The brain itself is soft and too fragile, although it is protected by the skull, it is still very susceptible to physical trauma, a slight brain ** is already very uncomfortable, and a serious injury may be directly disabling or fatal. I once thought that if the brain and spinal cord have become bones, it will be difficult to be injured, here is a point, that is, bone cells can also transmit information between them, similar to nerve cells, and can even be transmitted far away, but the mechanism is unknown for the time being, at present, it is mainly believed that the information shared between bone cells is about the state of bone pressure and bone repair, but now it seems that if nerve cells become bone, there may be several problems:

Nerve signaling became less efficient, and the most responsive people were about the same as people with dementia today.

The spine should not be as flexible as it is now, and movement is greatly limited.

Because the brain has become solid, it can basically not be buffered, it can only resist hard, and knocking it is similar to knocking on the triangle, the whole brain is vibrating, and it is impossible to think.

Don't try it lightly

The existence of the blood brain barrier (BBB) makes it impossible for most drugs to penetrate the brain to produce ** effects. The blood-brain barrier has a total of three layers from the capillaries in the brain

The first layer: the endothelial cells of the cerebral capillaries are very tightly connected with each other, and do not have large gaps like the vascular endothelial cells of other tissues;

The second layer: the endothelial cells of the cerebral capillaries have a basement membrane outside the cell, which is continuous;

Layer 3: 85% of the outer surface area of the cerebral capillary wall is surrounded by the terminal foot or foot plate of glial cells.

The main function is to prevent harmful substances in the blood from entering the brain, except for oxygen, carbon dioxide and blood sugar, almost all substances are not allowed to pass, drugs and proteins are generally macromolecules, so they are basically isolated. However, it brings a problem, that is, when the brain undergoes pathological changes, or only for the early stage of mental patients, it is difficult to develop the best drugs, because the drugs must not only meet the first effect, but also be small enough to cross the blood-brain barrier. Fortunately, with the advancement of technology, more and more methods have been developed to carry drugs across the blood-brain barrier.

There is no difference between the brains of humans with IQ defects and normal humans, and the structure seems to be the same. It's just that the function of the brain is not fully developed.

There are differences in brain function, structure, thinking mode, logic, thinking direction, and genes with normal human brains.

If the IQ is deficient, life will be more difficult, the perception of the outside world will slow down, the attention will be distracted, the things to pay attention to will be very narrow, the memory will be relatively poor, it will take many studies to master some knowledge, and if you don't review it, you will forget it in a short time.

Functional areas are underdeveloped, sometimes the brain is abnormal, and some people have brain malformations, different brain volumes, and viral infections may occur.

Generally, people with IQ defects will have different meanings than normal human brains, with different sources and different emphases.

Think about what is the most important part of the human body? What is the smartest part of the human body?

Is it the brain, why?

Because it's the brain that tells you.

In medicine, the human body is defined as death not when the heart stops beating, but when the brain dies, it sounds like it is true, and if the heart stops, it can be rescued, and the brain dies and dies.

But in fact, the brain is still flawed to the extent that humans are currently developing.

Everyone should have heard the story of "once bitten by a snake, ten years afraid of the well rope", in fact, this shows that the sensitivity of the brain cannot be controlled. Some people say that this has something to do with personal courage, yes, it is indeed related to human psychology, but more factors are still in the brain's anterior cingulate cortex and its neuronal NR2B receptors in the handling of terrorist events. Even if you know that there is no danger, you will still be afraid, and it is only after tedious desensitization that your brain will inhibit the response of this receptor.

Also, our brains "trick" us.

Many people will think that it is our personal life experience that makes our habitual thinking lead to mistakes, but in fact, there are also brain reasons. In social psychology, the term "Lake Ubigon Effect", also known as the Lake Wobogun Effect, refers to the psychological tendency of people to feel that everything is above average, that is, to rate many aspects of themselves higher than they actually are.

Our brains give us feedback that is not equal to the information. This means that the brain likes to obscure the information it receives, but it does give us definite information. For example, the glamorous world, such as the logic that thinks it is very logical.

But in fact, the brain does not agree with logic, and according to instinct, logic only exists with acquired training.

The essence of life is the constant movement of the contradiction of the process of assimilation and alienation in the organism; Death is the end of this contradiction.

Because the human brain is relatively fixed, there will be some irreversible defects.

This is the root cause of birth, old age, sickness and death, otherwise it would be a disaster for the planet if people deciphered this defect.

This may just be the case for some people, because people think that the brain has its own flaws.

Because the formation of the brain is fixed, defects can be corrected.

The structure of the brain is perfect, but it can also have some flaws.

The normal process of assimilation and alienation of various tissues and organs in the human body.

Because people are not perfect, there is such a saying.

Actually, this is not the case, the human brain is still very perfect.

Knowledge is our memory, in short, memory is the result of experience and cannot be transmitted through genetic material.

What our parents gave us was a blueprint, a directive to build humanity (or more specifically, to build us, because it is a mixture of two unique blueprints). It's not a blank slate, just like a house doesn't just have four walls, it also comes with utilities, bathrooms, and kitchens. Humans also have some additional functions, including walking, speaking, senses, intelligence, and personality, and a lot of things are determined by genes.

Over time, the house becomes home, and over time, the person becomes a unique person (this starts before you are born). Memories and experiences make us who we are today. The way we live affects our genetic potential.

This may be deliberate, neurons are special in that we only grow up when we are young and are inhibited afterwards. It's like you plant a bush and cut it into shape instead of trying to make it grow at will. We don't know how memory works yet, the brain is really complex, so we need more time.

But we do know a few things.

The best way to think about memory is to think of it as a network (not a computer file)! Memories are like a path that is carved into the network by connecting different neurons.

Because we're just too complex to pass on our memories, we grow up in a way that doesn't allow for that. We have to do it in the traditional way by teaching and sharing our experiences.

We are born with some practical tools. Humans automatically learn to walk and talk, but this requires a lot of practice. Our biology is very much inclined to make this possible, but these pathways need to be created.

However, there are a few things that don't require this kind of learning, such as reflexes (we don't discuss whether reflexes count as memories).

That being said, not all experiences are gone. Epigenetics tells us that, to some extent, the environment can alter the way genes are expressed, and this alteration can be passed on to future generations. If something happens that forces the organism to adapt, such as famine, these experiences are passed on.

Children now inherit their parents' experience to some extent.

It's not that human thought can't be inherited, it's just that it's not as strong as the programmed inheritance like spiders, maybe it's too precise and difficult to inherit, so thought inheritance is something worth studying. So I think humans are arrogant when they say that other creatures are inferior or something, at most other creatures are just temporarily behind humans, and it is possible that other creatures have surpassed you humans overnight, as evidenced by those creatures who are born and those docile dogs, dolphins and other animals. It can also be seen from the irritability of some humans and the various shortcomings of human beings, that human beings are not as intelligent as they seem.

Because human inheritance is carried through genes, and acquired knowledge does not have genes, so it cannot be inherited, if one day genetic mutation, genes also contain acquired knowledge, then knowledge can also be inherited.

Because the brain is like a memory, and the brain of a newborn is like a brand new piece of hardware, it can only be learned.

Because knowledge is learned through nurture.

Because this knowledge is acquired, not genetically acquired.

Because this only exists in the subconscious of the human brain.

Because knowledge is a very difficult thing to understand.

The knowledge in the human brain is not something that comes from innate genes.

Because these things are acquired.

Because this knowledge is not acquired innately.

Because this knowledge is acquired, not genetic.

Because this knowledge is acquired.

I don't think the word "defect" is a good word here, especially when it comes to the brain. At present, the exploration of the brain is still in its infancy, and many understandings are based on observations and assumptions, and the fundamental operating mechanism is still unknown. For a thing that you don't know deeply, it's a bit hasty to ask directly where its "flaws" are.

And, how do you define "brain defects", I picked up a stone on the side of the road, asked you what defects this stone has, you said that the stone is too hard to hit people must have a big problem, this is a defect, I said that this stone is hard just to use to open walnuts, isn't this useful, it is better to ask, what are the limits of the brain, what characteristics will have a possible negative impact on our daily life, I will briefly say a few of my own opinions: the brain itself is soft and too fragile, although it is protected by the skull, It is still very susceptible to physical trauma, a slight brain ** is already very uncomfortable, and a more serious injury may be directly disabling or fatal. I once thought that if the brain and spinal cord have become bones, then it will be difficult to be injured, and here is a point, that is, bone cells can also transmit information between bone cells, similar to nerve cells, and can even be transmitted far away, but the mechanism is not known for the time being

Nerve signaling became less efficient, and the most responsive people were about the same as people with dementia today. The spine should not be as flexible as it is now, and movement is greatly limited. Because the brain has become solid, it can basically not be buffered, it can only resist hard, and knocking it is similar to knocking on the triangle, the whole brain is vibrating, and it is impossible to think. These assumptions may not be perfect, so you are welcome to open your minds. In short, the brain is fragile, so don't forget to wear a helmet if necessary to reduce the risk.
