Why does the human brain delete memories before the age of 3? Are human memories automatically era

Human memories are not automatically erased. The brain deletes memories before the age of 3 because when the baby is just born, everything is new to the baby, and the baby does not have a clear concept of things at all, so the baby only produces visual memory, and the baby remembers the picture they see. Babies don't understand what mom and dad are, what toys and books are, babies just instinctively think that these are the things around them.

As a result, the lack of "concepts" makes it difficult for babies to form a network of "cues" in their own brains, and all their memories are individual "picture memories", making it difficult to form long-term memories.

Because the human brain weighs very little before the age of three, it does not have as much brain capacity to store memories; People's memories are automatically deleted, because the brain capacity is very small, so there are not many things that can be remembered, so they are automatically deleted.

It may be that the child's memory before the age of three is relatively vague and the brain has limited storage space, so it will be automatically deleted.

The brain does not erase memories before the age of three, but no one can remind them of some clues related to the memories before the age of three, and if they can, they will remember them. When I was young, I was most impressed by my mother's face.

This may be due to the immaturity of the brain, but I don't see anything, and I think it's very normal.

The brain doesn't delete the memories of childhood, it's just that the memories are blurry and I can't remember them.

The reason why most people can't remember things before the age of three is mainly because of the following three reasons:1. The human brain is not fully developed before the age of three; 2. Human beings do not know the meaning of things before they are three years old; 3. No ability to express before the age of three

First of all, many scientists believe that before the age of three, the brain is actually incomplete, many educators also recognize this statement, so it is not recommended for children under the age of three to go to class, whether it is early education or kindergarten is not recommended, in real life most children are three years old before they start kindergarten, this is because after the age of three, the child's brain is gradually fully developed, this period of children to know what is happening around them what it means, Therefore, it is very likely that children before the age of three will not be able to remember things at all, after all, the age is really too young.

Secondly, there are some scientists who believe that there are actually memories before the age of three, but after the time is getting longer and longer, it will be gradually forgotten by everyone, especially after a person becomes an adult, most of the things before the age of six cannot be remembered, and only remember some of the more impressive, which is also a very normal thing.

In addition, children before the age of three do not know what a thing means, and it is naturally impossible to remember, after all, we must first know the world, so that we can know what is happening in the world, and then remember what is happening in the world, which is also the law of nature.

Finally, children before the age of three may not be able to speak, and too good at expression, so children at this period to see, hear, can not be translated into language, when they grow up to see red flowers, the brain will be directly defined as high oak saffron, the mouth can also speak, but when the brain does not have this definition, the mouth can not speak, such imitation of the West is naturally not remembered.

This is called infantile amnesia. Before the age of three. Human memories are vague, and over time, this memory will disappear.

The main reason why many people do not have a model before the age of 30 is that in the process of their growth, because the capacity of the brain is limited, they will slowly forget the previous memories, and the brain has an automatic elimination mechanism.

Because after birth, many things will only have visual memories for people, and there is no concept at all; Of course not.

At this time, it is the rapid development stage of the brain, so the words will be deleted, and the memories of our children under the age of three are still relatively small and very vague.

This phenomenon has a professional term in psychological medicine called "childhood amnesia". This symptom refers to the fact that when a person recalls things from their childhood, many people can hardly remember any clear, complete details, and psychologists will call this phenomenon "childhood amnesia". This concept was first proposed by the famous psychologist Sigmund Freud more than 100 years ago, and later according to statistics, it was found that the age stage of amnesia is mostly between 3 and 4 years old, and few people can remember what happened before the age of 3.

Freud believed that the human brain does not delete these things, but stores these early memories in a special place that psychology calls the "subconscious". I don't have any memories of when I was three years old now.

Because the human brain thinks that the memory before the age of three is very fragmented, it is a short-term memory, and it will be automatically cleared, and I have memories over the age of three.

The reason why the brain deletes memories before the age of three is that neurons appear in the brain that are stored in excess of them.

The memory in the human brain is stored in the neurons and the links of neurons, and the reason why the human brain has amnestics is mainly because there are neurons with excess storage in the brain, just like mobile phones, there are too many stored contents, and it is inevitable to delete some useless things, and then save useful things, the same is true for the brain, and the brain is not infinitely stored. What's more, things before a few years of age are of little value, so they are naturally the first choice when deleting them.

In fact, when babies or slow workers are very young, the brain has no cognition of the outside world, including their parents, and they are only regarded by the brain as two objects, and there is no specific concept, so what we see when we are children is something unknown to our brain.

The development of the human brain

The embryonic brain primordia usually begins to emerge around twenty days of gestation. At two months, when the left side is buried and the right side is buried, a clear contour of the sulcus gyrus can be observed. At about three months, brain cell development peaks; At about six months, the sulcus gyrus appears on the surface of the brain and is able to show the basic level of the cerebral cortex.

At about seven months, the central motor function of the brain is relatively well developed. At this time, the fetus has the ability to think and remember, and in about eight months of pregnancy, the sulcal gyrus on the surface of the brain has been basically formed.
