Memory Enhancement Fetal Brain Development

Memory is a mental function that keeps a stimulus in your head and reminds you in the absence of a stimulus.

Memory is the mental function of feeling a stimulus (learning) and keeping it in your head, and then recalling that information after the stimulus is gone. Without humans’ ability to remember, there would have been no intellectual growth or development. Thinking, judgment, and learning are all brain functions based on memory.

Short-term memory is a function of short retention time. This is relatively unstable, and memory is easily lost if the head is traumatized or unconscious due to electric shock. However, some memories are hardened by various deformations and may not disappear by head trauma or electric shock. This memory is called long-term memory. This is because information is firmly fixed in the brain and remains as a trace of memory.

Long-term memory does not exist in the form of substances
As humans grow, the number of branches of nerve cells increases and becomes thicker. Synapses in the area where the nerve conduction is active, thickening with the development of new branches, the excitation conducts more smoothly. This structural change activates a specific synaptic circuit, making it easy to cross the excitation conduction circuit. This action of neurons makes memories deeper, longer pinned to synapses, and carved into traces of memory, making it easier to recall.

When the excited conduction between synapses occurs smoothly, the synaptic circuit is strengthened and thickened. If this process is repeated, long-term memory remains.

The synaptic circuits that you continue to use are activated and strengthened, but the unused circuits are lost. In other words, long-term memory does not exist in the form of a special substance, but is engraved as a trace on a thickened synaptic site for a long time.

There are three stages of memory. The first is to memorize new knowledge and enter it into the brain, the second is to memorize what is stored in the brain, and the third is to recall again. However, if any of these three steps are abnormal, you will not be able to remember them correctly. An example is Alzheimer’s disease, commonly called dementia.

In Alzheimer’s disease, the hippocampus, which plays an important role in entering memory, is damaged or broken. For this reason, dementia patients are not able to enter the memory information well, so they do not remember recent events. But long-lasting memories firmly stored in the brain are not related to the hippocampus and can be recalled by dementia patients. As another example

If the cerebral cortex is damaged by various factors, such as trauma or dementia, the memory stored in that area may be lost. At this time, there is no problem with other memories, but memories stored in specific regions cannot be recalled.

The memory process takes a lot of emotion
In general, memory processes are known to be heavily influenced by emotions. Two kinds of memories are usually vividly remembered for a long time, usually very funny and sad memories. These memories can come to life vividly without forgetting, even after many years, because during this emotional state, information is easily entered and stored firmly in the brain.

Memory can be more easily recalled in a pleasant state than when you are depressed. Therefore, it is much more effective to induce children to have fun studying in order to have a long memory for children who must always learn. Studying happily increases attention and makes learning information easier to enter and store, making it easier to remember.

To maintain good memory, the role of the deactivation system is also important. In the middle of the bottom stem of the brain is a net of nerve cells that keep the mind clear and awake. It is called delusional activation system. The net of these neurons is the brain at the top of the brain

It keeps on stimulating nerve cells, keeping your mind clear and allowing you to focus on one place. When the emotions are complicated or diverged, this deactivation system is also scattered and suppressed. At this time, attention is distracted, the memory is not input well and the recall is not good. To maintain good memory, first of all, you need to have fun and interest in what you want to remember, have a pleasant mind, and stabilize your emotions, because this is good for stimulating the delusional activation system.

The delusional activation system keeps the mind clear and increases concentration. If you have high concentrations, you can remember the stimuli you received much better (left). When stimulated in a pleasant state, the hippocampus, the brain of memory, is activated. At this time, the frontal lobe in front of the hippocampus is also stimulated and motivated, and the memory is firmly stored (right). <Source: Yoo Heon Suh, [Mother’s Brain Training for the Future of My Child]>

Memory function is effective, the brain of reason and the brain of emotions must cooperate
Memory functions in the newly evolved neocortex (the brain of the opposite sex) and the old cortex (the brain of emotions) created long ago. Therefore, in the cortex and neocortex, memory can be effective in cooperation. If you simply memorize knowledge without reason, only the brain of the cortical animal develops. If you repeat the animal simple memory is good. However, a variety of complex information.

When you do it in a pleasant mind, the hippocampus, the brain of memory, is activated. Then the memory is well input and the brain of motivation in the frontal lobe of the hippocampus is stimulated to generate motivation, and the memory goes up to the cerebral cortex, which is firmly stored and recalls well. This is why it is much more effective to mobilize the entire neocortex and the cortex than to mobilize part of the brain when solving some problems.

If you want to improve your memory, be honest with your emotions.

Studying happily will not only improve your memory, but also motivate you, and increase your learning.

A new study recently reported that short-term memory decreases when a person is restrained and indifferent to expression. When watching a movie, when a funny and funny scene comes out or when a sad scene comes out, it is reported that the memory of the movie decreases when the emotion is suppressed to prevent laughing or crying. Emotion center

Since it is attached to the hippocampus, which is the memory center, it is natural to remember when it is pleasant. Suppressing emotion unnaturally reduces memory because only a few cells participate in the memory process.

For example, working in a coercive environment or dealing with a coercive attitude, people die of their emotions and keep their emotions hidden. Softer, more democratic treatments are not only good for their members, but also for their memory.

* World Brain Week Event
World Brain Awareness Week, held worldwide from March 13 to 20, 2010, will be held in 10 cities in Korea. Leading neuroscience researchers in Korea will introduce the latest research results on brain function and brain diseases to the public. Anyone can attend this event for free, and more details can be found at the Korean Brain Society.



Long stimulated, it must be activated. ”

Even people who forget where they put their keys remember well. What is the reason? In a recent study published in the latest issue of Science, Harvard and Stanford University researchers in the United States found that when something is seen, the frontal and hippocampal areas of the brain are prone to prolonged irritation. Scientists have long thought that what experiences are well remembered or easily forgotten depends on how much they are engraved when they enter the brain.

Frontal lobe and hippocampus correlated deeply with memory

When the frontal lobe and hippocampal cortex are activated, you can better remember. Source: Wagner et at. Science (1998)>

The research team, led by Harvard University’s Dr. Wagner, connects subjects to magnetic resonance imaging (MRI), illuminates words on the screen every two seconds, initially asking whether they are uppercase or lowercase, The memory test was done by asking whether the word (a chair or a book) or an abstract word (love and hate).

Dr. Wagner asked them what words they remember best, words that are faint, and words that they do not remember, and compares them with brain activity observed through MRI. As a result, it was found that the longer the time for the frontal lobe and the hippocampus to operate, the longer the word was remembered and the shorter the word was forgotten. Similarly, patients with Alzheimer’s disease (dementia) with damage to the frontal lobe or hippocampus have problems with short-term memory.

Helps to reduce brain fatigue and improve memory

Studying when you are tired does not help you remember the content.

Dr. Donald Hebb, who first presented the famous Hebb synapse and was known for his memory studies, experienced a severe memory loss at age 47, when he was working hard. As I read the paper, I thought I should write down what I needed to do, and I was shocked to discover that it was already written. At night, however, I stopped working and rested, getting enough sleep and replenishing my nourishment.


Several research teams have reported that sleep strengthens memory. One of the memories, the Visual texture discrimi nation task, remembered the longer the RAM and slow wave sleep time, and the motor sequence task, the second stage of sleep, nREM time. Memory lasted in proportion to.

In addition, the motor adaptation task was strengthened in proportion to the slow wave sleep, which is the fourth stage of sleep. Reducing brain fatigue like this can help you keep memories for a long time. To do this, stop mid-day work, get adequate rest, and sleep well. In other words, don’t try to remember a lot when you’re tired, but think about the brain’s storage space and inject it properly.

There is a proportional relationship between different kinds of memory and the amount of sleep it affects.

Stimulating the vagus nerve increases memory
Dr Robert Jensen, a professor of psychology at the University of Southern Illinois in the United States, said in a study published in NatureNewsScience. The reason I remember well is because of the vagus nerve, the parasympathetic nervous system.

The vagus nerve is a parasympathetic nervous system that extends from the brainstem to almost every organ in the body, transmitting brain commands to control the heartbeat, and providing information about the status of each organ, including whether the gastrointestinal tract is empty. It plays two roles. Dr. Jensen’s mouse experiments show that the emotionally long-lived events are thought to be due to the stimulation of the vagus nerve, the parasympathetic nerve.

Sad memories such as the death of acquaintances last long due to the vagus nerve, the parasympathetic nervous system.

Dr. Jensen actually tested ten subjects to read a multi-line sentence in which 42 of the 250 words were yellow, and then recalled the yellow words. Two times before and after stimulating the vagus nerve with a special device, the score after the vagus nerve stimulation was 36% better than before the vagus nerve stimulation. Therefore, stimulating the vagus nerve can improve memory. Dr. Jensen said the finding could one day help restore memory in stroke patients and brain-damaged patients.

But Jensen says it is questionable whether vagus nerve stimulation will help patients with Alzheimer’s disease or those who put a lot in their heads for testing. Dr. Jensen points out that rats have shown that too much stimulation of the vagus nerve results in a loss of memory. If you put too much in your head, you think you’ll exceed the limit of memory.

Forgetfulness is different from dementia caused by brain cell damage
Generally, when you enter a lot of information at once, it is stored as a memory. Even if it is hard to store well, if a strong stimulus comes in easily get out and forget. That everyone experiences most commonly

Forgetfulness does not appear because brain cells are damaged by toxic proteins like dementia, but because they enter a lot of information at the same time or do not pay attention. Therefore, to avoid forgetfulness, it’s best to focus your attention and enter them one at a time. Also, repeatedly memorizing many things without understanding does not help you maintain good memory.

When we watch TV for a long time, memory falls

If you watch TV for a long time, you will lose your memory.

A study in Australia analyzed the relationship between memory and lifestyle, and found that people who watched TV less than an hour a day had more names, faces, jobs, market views, and lists than those who watched TV more hours. Memory was good in all areas including memorization. It was also found that people who lived actively, such as reading novels and paying attention to their diet, had better memory than those who did not.

If you are watching enough to distract you from a TV that only delivers a lot of time unilaterally,

Cranial nerve cells are easily worn out. In addition, it is passively influenced by TV contents, making it difficult to actively think about various things. Therefore, it is good to keep good memory in mind to keep in mind that it is not possible to transmit various information to brain neurons, and the memory will fall.


There is work to be done and work not to do. ”

The human brain begins to grow from the moment it enters life, not just as the number of neurons (neurons) increases, but as the nerve cells grow and the synaptic branches that connect between them become dense and thick. The “signals” that enter the brain are handled by neural circuits that connect brain cells, and they can be said to have “intelligence” when the complex and sophisticated synaptic networks that process the signals are completed. In other words, high and low intelligence is determined by the well-developed synaptic branches rather than the simple weight or size of the brain.

Intelligence consists of the development of sophisticated synaptic networks
This brain organization begins to occur after six months of pregnancy. During this period, brain cells develop rapidly enough to produce about 50 to 60 million brain cells every day. Through this process, newborns are born with more than 100 billion brain cells. The structure of the brain is determined by genes, but the number of synapses and the type of communication are affected by the environment. In other words, the framework of intelligence is made by genes, but the fine structures and functions that determine its contents are driven by education. Therefore intelligence.

Synapses’ network development leads to intelligence.

The brain of the fetus continues to develop from early pregnancy until after birth
1 month – already a basic brain structure

At the fourth week of pregnancy, the first three weeks of structure of the basic brain (1 layer: rear brain, 2 layers: middle brain, 3 layers: whole brain) is formed.

3 months-slowly develops memory

By the third month of pregnancy, the head, torso, arms and legs are clearly distinguished, and the brain is also in shape, performing various functions. The fetus gradually remembers external stimuli, but it is not yet a memory like an adult, but when a stimulus is induced by a mother’s behavior, it is transmitted to the brain and leaves a trace. Therefore, at this time, mothers should never drink or smoke in their mouths, so that they should not be stressed and actively relieve stress.

5 months-can hear sound

The fetus was quiet from now on, moving the feet in the amniotic fluid actively. At this time, the brain of the fetus develops more than 80%. In particular, the development of hearing can hear the high and low sounds coming from the outside, but the meaning of the sound is not understood. Therefore, fighting loudly should be avoided, and it is good to keep the mother’s feelings happy and calm.

7 months-express emotions as kicks

At this time, a preference for outside sounds occurs. The most favorite sound of the fetus at 7 months is the soft voice of the mother. Also, when you hear beautiful music, nature sounds such as birds, insects, stop moving and listen quietly. The reaction to the outside is also quick, so when the mother knocks on the boat, she kicks it to the place where she kicks.

8 months-short-term memory begins to form and distinguishes sound intensity

Some short-term memory has been formed and reported to store simple information for several minutes to hours. This does not mean that it is remembered. At this point, the bad stress on the fetus has a negative effect on the fetal brain, so be careful. At this time, the ability to distinguish between the strength and weakness of the sound is made, and the mother’s voice is perceived according to the strength of the mother. Therefore, if the mother is happy and happy, the child will play comfortably.

10 months-prepares to leave head in pelvis

The fetus at this time knows that the time has come instinctively to go out into the world. It stops kicking kicking, leans back and puts his head in the lower pelvis, ready to come out.

For the brain development of the fetus, the womb environment is important
1. Drink fresh air for brain development

The fetus’s brain develops mainly between the four and six months of pregnancy, especially during this time, where the cerebral cortex, which contains thoughts (the brain of intelligence), emotions (the brain of emotions, the brain of animals), and the movement center, grows very rapidly . The fetus receives nutrients and oxygen from the mother through the placenta, and the brain is most sensitive to oxygenation in our bodies. If you have a rich supply of oxygen and nutrients during this period when your brain is actively developing,

A child with a well-developed brain is more likely to be born. The human brain loses consciousness or dies because of damage to nerve cells that can’t be reversed without blood supply for only two or three minutes. Therefore, it is important to provide oxygen and proper nutrients to the fetus, so that pregnant women stroll through the air or parks where the air is clear.

Pregnant women should drink fresh air to supply the baby with fresh oxygen.

Fresh air is especially important for brain development and communication.

Increases the synthesis of neurotransmitters Therefore, strolling in the fresh air not only smoothly supplies oxygen, which is essential for the development of the brain of the fetus, but also helps the blood circulation in the mother, and helps to relax the stress to help maintain the mind and mind calm. Therefore, walking pregnant women with fresh natural air is better than any medication.

2. Both fetuses and pregnant women should eat three nutrients evenly

Pregnant women should eat three nutrients evenly. Alcohol should never be avoided.


To develop brain neurons, the protein, the source of neurotransmitters, the carbohydrates that cause the brain cells to move, and the fats that make up the cell membrane, must be ingested evenly. The brains of nine children who died of protein malnutrition within two years of life were dissected and compared with healthy children, indicating that the brain contained less weight, protein and nucleic acid. And protein deficiency early in life

It also reduces the number of brain cells and makes them brain cells that no longer grow. Therefore, eat foods high in protein, such as milk, beans, fish, cheese, eggs, tofu, and meat.

Carbohydrates are the only source of energy to move brain cells, so proper supply is essential. Fat is indispensable in forming brain cell membranes and organelles, and since it is the most abundant component of brain cells among all organs, even intake of three major nutrients is very important.

“ Vitamin B Group, an assistant in the synthesis of neurotransmitters
If you lack vitamin B, your character is rushing and you have less memory. The driving force and inhibitory power of brain cells are the amino acids that are the source of neurotransmitters, because the synthesis of neurotransmitters requires the help of vitamin B group, which acts as a coenzyme.

Free radicals and waste suppression ‘Vitamins A, C, E

In order for a cell to be healthy, it must have no waste, and so does the brain. This is because the removal of waste products from the brain is linked to the activity of the brain. Grain proteins and vitamins A, C, and E play a role in inhibiting the production of peroxides, which are the waste products of oxygen combined with fatty acids. The three work together to act as antioxidants to remove brain waste.
3. Avoid foods or drugs that contain caffeine that can destroy brain cells

Alcohol and tobacco should be avoided because they can destroy the brain cells of the fetus. Ingestion during pregnancy inhibits brain development, leading to cerebellar disease (small brain) (fetal alcohol syndrome). Caffeine products, such as coffee, cocoa and cola, can cause vasoconstriction to inhibit fetal oxygen supply and interfere with the absorption of iron and calcium, thus blocking nutrients supplied to the fetus. It is well known that oxygen blockage has a fatal effect on the brain. It is also important to keep in mind that drugs can damage the fetus’s brain directly, increasing the chances of having a mentally challenged child.

4. Stress from pregnant women can be transmitted to the fetus through the placenta

If the mother is constantly exposed to stress, the increased stress hormones, steroids, adrenaline, and beta endorphins in the mother’s blood, can inhibit brain development and constrict the uterine muscles, reducing blood flow to the fetus. This cuts off the sufficient supply of oxygen and nutrients, causing fatal damage to the brain of the fetus. Also mom’s

Stress is transmitted throughout the placenta to the fetus, which can cause psychological disorders such as autism, pediatric diabetes, and high blood pressure if the fetus experiences tension and excitement frequently. The adrenal glands are easily fatigued and can cause severe brain atrophy.

5. Infection can cause malformations: be careful not to get swine flu or rubella

It is often said that pregnant women should take care of themselves and be careful not to go to places where many people gather. It is good to be careful about your mind and body, but it’s good to avoid infectious diseases in places where a lot of people gather. The new flu has been around the world. The swine flu

Not only can a pregnant woman’s life be at risk, but it also increases the risk of miscarriage and maternal high fever can cause birth defects and death in the fetus. . When a high-risk pregnant woman is vaccinated, they not only help her produce antibodies,

Antibodies are delivered to the fetus to prevent infection in newborns after delivery. All pregnant women are at high risk, and if the swine flu is confirmed or suspected, the antiviral drug Tamiflu is recommended for both the fetus and pregnant women. Tamiflu does not increase the incidence of birth defects in the fetus. The mortality rate is less than 0.1% lower than that of the general flu, but especially pregnant women and infants with weak immune function can be dangerous, it is important to sleep and rest well while maintaining good nutrition.

Also pregnant women

If you have rubella, your fetus may have a heart problem or loss of vision or hearing. In addition, these infections enter the fetus’s brain and cause mental retardation. If rubella is prevalent, don’t go out and avoid contact with people. In addition, if you have rubella patients in your family, get a gamma globulin injection. In addition, when infected with the herpes virus,

Pregnant women should always be cautious, as severe disability of the central nervous system may occur, resulting in visual impairment or death in severe cases.

Since more than 100 billion brain cells are all produced during fetal periods, it is of utmost importance for a healthy child to have a healthy, healthy diet of three nutrients in fresh air.
