Scientists believe that memory can be divided into short-term memory, medium-term memory and long-term memory. The essence of short-term memory is the repetition of immediate physiological and biochemical reactions of the brain, while mid-term and long-term memory are structural changes that have occurred within brain cells and the establishment of fixed connections. For example, how to ride a bicycle is a long-term memory. Even if you haven't ridden for many years, you can still get on the bike and run. Mid-term memory is a fragile change in cell structure. Only by repeatedly consolidating it by "keep singing and punching" can it become long-term memory. Short-term memory is the most numerous and least stable memory. A person retains only 1% of his or her memories every day.

Understanding that memory requires constant review to consolidate, you can master the secrets of enhancing memory from both material and technical aspects. In terms of substances, eat more foods that are good for memory, such as celery, walnuts, sesame seeds, lean meats, etc., which are rich in zinc, phosphorus esters, and certain unsaturated fatty acids.

The technical aspect is actually to follow the physiological laws of memory.

First, you must listen attentively, think and absorb in class, and acquire deeper short-term memory.

Review on the same day after class; consolidate it again and organize it in a few days when the memory starts to fade. "It is a pleasure to learn and practice from time to time." I will review it every one or two months in the future. In this way, short-term memory can be turned into medium- and long-term memory, and the best memory effect can be obtained in the least time.

Secondly, it is best to review the lessons to be memorized in a quiet environment in the morning or at night.

Experiments have proven that 6-10pm and 6-8am are the best times for memory function. At the same time, you must concentrate and do not be distracted or interrupted by other people. Don’t endorse while listening to the walkman. This is because the brain only allows one center to be in an excited state when working. If there are several excited points at the same time, it will inevitably be absent-minded or half-hearted, which will greatly reduce the memory effect.

Third, be comfortable and not nervous when memorizing things.

The secretion of norepinephrine increases during stress, which is the enemy that damages mental concentration and memory. On the contrary, in a relaxed environment, the posterior pituitary gland secretes vasopressin, which is very beneficial to enhancing memory function. Of course, memory can also be improved through software training, see reference materials.

Fourth, you can compile some jingles to organize and outline the knowledge, so that the knowledge can form a memory system and network, so that the memory effect can be increased through association.

For example, when you want to remember the names of the "Eight Great Masters of the Tang and Song Dynasties", you can first remember the eight surnames "Han, Liu, 'Sansu', Ou (Yang), Wang, and Zeng", and then you can easily infer them. All names and so on. Fifth, try to understand what you want to remember. The so-called understanding, physiologically speaking, is to incorporate your knowledge into the memory network and establish a deep fixed connection. Memorizing things you don’t understand is a waste of memory and you won’t remember them well.

How to enhance memory?

Memory is the reflection of past experiences in the human brain. It includes three basic processes: memorization, retention, reproduction and recall. Its forms include image memory, conceptual memory, logical memory, emotional memory, motor memory, etc.

The enemy of memory is forgetting. Improving memory actually means trying to avoid and overcome forgetting. As long as you carry out conscious exercise during learning activities and master the rules and methods of memory, you can improve and enhance your memory. Here are ten ways to enhance your memory.

1. Pay attention. When remembering, as long as you concentrate, concentrate, and eliminate distracting thoughts and external interference, the cerebral cortex will leave deep memory traces and make it difficult to forget. If you are distracted and multitasking, your memory efficiency will be greatly reduced.

2. Strong interest. If you are not interested in learning materials and knowledge objects, it will be difficult to remember them no matter how much time you spend.

3. Understand memory. Understanding is the basis of memory. Only what you understand can be remembered firmly and for a long time. It is not easy to remember just by rote memorization. For important learning content, if you can combine understanding and recitation, the memory effect will be better.

4. Over-learning. That is, on the basis of memorizing the learning materials, memorize them several times to achieve the level of memorizing and remembering them by heart. The optimal level of overlearning is 150%.

5. Review in time. The speed of forgetting is fast at first and then slows down. Strike while the iron is hot and review and consolidate the knowledge you have just learned in a timely manner is an effective means to strengthen memory traces and prevent forgetting.

6. Remember often. When studying, continuous attempts to recall can correct memory errors, make up for omissions, and remember difficult learning content more firmly. In your spare time, you can also avoid forgetting by frequently recalling the objects you memorized in the past.

7. Combine reading, thinking, seeing and listening. You can use the functions of language and visual and auditory organs at the same time to strengthen memory and improve memory efficiency, which is much better than silent reading alone.

8. Use a variety of memory methods. Depending on the situation, flexible use of classification memory, characteristic memory, homophonic memory, argumentative memory, associative memory, interesting memory, chart memory, shortened memory and compilation of outlines, note-taking, cards and other memory methods can enhance memory.

9. Master the best memory time. Generally speaking, the best memory times are 9 to 11 am, 3 to 4 pm, and 7 to 10 pm. It is better to use the above time to memorize difficult-to-remember learning materials.

10. Use your brain scientifically. On the basis of ensuring nutrition, active rest, and physical exercise to maintain the brain, scientific use of the brain, preventing excessive fatigue, and maintaining a positive and optimistic mood can greatly improve the work efficiency of the brain. This is the key to improving your memory.

Memory can be improved through training. In ancient and modern times, many celebrities and scholars at home and abroad pay attention to using various methods to exercise their memory. For example, the great Russian writer Tolstoy once said: "I do two kinds of exercises every day, one is morning exercises, and the other is memory exercises. I memorize and read foreign language words every morning to check and cultivate my memory." Tolstoy's "memory exercise" is actually repeated "recurrence". As long as you "repeat" in a planned way, your memory will continue to improve.

The following methods of training memory are very effective, you may wish to refer to them regularly.

Suggestion method - positive.

Many people often lament "I have a bad memory". This is partly due to the passing of time, but also because they lack sufficient confidence in their own memory. Faced with a series of foreign language words or a large amount of materials, some people think: There are so many, can I remember them? In fact, this creates a barrier to my own memory. You should encourage yourself: "I will definitely remember it." This is a positive psychological suggestion. Think about the time when you were able to memorize Tang poems by heart when you were a child; think about the times when you reviewed carefully before taking exams and got the top spot.

One of the reporter’s friends, Ms. Dong, has often been troubled by her poor memory and always forgets things. But her college classmate said: "What's the difference? When I was in college, I reviewed ancient literature half a month in advance. You only rushed two days in advance and scored more than 90 points in the exam, which is higher than me." Miss Dong smiled: " Yes, my memory is pretty good, I need to develop it well."

Strong memorization method - limited time.

Memorying numbers, names, words, etc. within the specified time can exercise the ability to memorize. For example, when waiting for the subway, you ask yourself to remember a few phone numbers and addresses on the billboard before the bus comes, and try to use your right brain to remember them. The next day, see if you remember everything. Don't think this is boring, this can fully mobilize your left and right brains, prevent brain aging, improve memory, and it doesn't cost a penny. This method can be done anytime and anywhere. Of course, you can also carry a few customer business cards with you and use your commuting time to write down the addresses and phone numbers on them.

Memory method——delicate.

We usually come into contact with many people and things, and remember a lot. However, because we seldom recall, many of the things we remember are blurred or forgotten. Recalling it often, and as carefully as possible, is a good way to exercise your memory. In the recent CCTV "Challenge the Host" program, the attacker and defender were required to observe a model in a short period of time, and then compete to see who could remember the most content. This content is very detailed, such as the color of the model's clothing, How many T-shirts were worn, what accessories were worn, where the accessories were worn, what decorations were on the shoes, etc... The memory of the two contestants was amazing. In fact, we can usually exercise our memory in this way. When you meet a person, recall the style and color of her clothes, hairstyle and color of her hair, the style and fabric of her handbag, etc. You can also recall the movie you have watched recently, what characters are in it? What happened? How does it end? Recall each shot carefully, the more detailed the better.

Don’t lament that you are busy at work, under great pressure, or you are old. These are not reasons for “memory decline”.

Develop your right brain and use your spare time to exercise your brain, and your memory will become more and more amazing.

Foods that are good for enhancing memory:

Drinking grape juice regularly can help extend your life. Moderate drinking of wine can have the same effect, but since alcohol can paralyze nerves, grape juice is a better choice. Grape juice contains more antioxidants than any other fruit and vegetable and can improve nervous system transmission. In addition to increasing longevity, grape juice can also improve memory in the short term.

Wild blueberries are rich in antioxidants, which can remove impurities from the body. Test results on mice show that long-term intake of blueberries can accelerate the growth and differentiation of neuronal cells in the hippocampus of the brain, improve memory, prevent the weakening of balance and coordination with age, and reduce the risk of high blood pressure and stroke. Probability of occurrence.

Other memory-enhancing foods

Some brain-strengthening foods are actually common and inexpensive foods. Such as egg yolks, soybeans, lean meat, milk, fish, animal offal (heart, brain, liver, kidney), carrots, cereals, etc. These foods are not only rich in lecithin and easy to digest, but also have a positive effect on the development of children's brain.

1 Milk. Rich in protein, calcium, vitamin B1 and amino acids necessary for the brain. The calcium in milk is most easily absorbed. When you are overactive or have insomnia, a cup of hot milk can help you fall asleep.

2 eggs. It is called a complete protein model by nutritionists and has a human body absorption rate of 99.7%. Normal people need one egg a day to meet their needs. People with memory loss can effectively improve their memory by eating 5 to 6 pieces a day (not suitable for people with high cholesterol). Eating eggs appropriately from a young age is beneficial to the development of memory; especially egg yolks, which contain lecithin, egg calcium and other nutrients necessary for brain cells, which can enhance brain vitality. .

3 Fish. Provides high-quality protein and calcium to the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which can protect cerebral blood vessels and promote brain cell activity.

4 Shellfish. It has very low carbohydrate and fat content and is almost pure protein, which can quickly supply a large amount of quinine to the brain. Therefore, it can greatly stimulate brain energy, enhance mood and improve brain function. Eating shellfish as an appetizer is the fastest way to improve your brain power. But shellfish are more likely than fish to accumulate toxins and pollutants in the ocean.

5 MSG. The main ingredient is sodium glutamate, which is the only amino acid involved in brain metabolism. It increases acetylcholine in the brain, promotes intellectual development, maintains and improves brain function, and improves memory.

6 Peanuts. Peanuts and other nuts are rich in lecithin. Regular consumption can improve blood circulation, inhibit platelet aggregation, and prevent cerebral thrombosis. It can delay brain function decline, enhance memory, and delay aging. It is a veritable "immortality fruit."

7 Xiaomi. Contains vitamins B1 and B2 1 to 15 times higher than rice. Clinical observations have found that eating millet is beneficial to brain health and prevents aging.

8 Corn. Corn embryos are rich in a variety of unsaturated fatty acids, which can protect cerebral blood vessels and lower blood lipids. The glutamic acid content is high, which can promote brain cell metabolism and has a brain-building effect.

9 Daylily. Day lily can soothe the nerves and relieve depression, but it should not be eaten raw or fried to avoid poisoning. It is better to eat it dry or cooked.

10 peppers. Vitamin C content ranks first among vegetables, and it is also rich in carotene and vitamins. The capsaicin contained in peppers can stimulate the sense of taste, increase appetite, and promote blood circulation in the brain. The "spicy" taste also stimulates the hormones in the human body that pursue career success, making people energetic and active in thinking. It’s better when eaten raw.

11 Spinach. Rich in vitamins A, C, B1 and B2, it is one of the best suppliers for brain cell metabolism. It also contains a lot of chlorophyll, which also has brain-boosting effects.

12 Oranges. Oranges, lemons, mandarins, grapefruits, etc. contain large amounts of vitamins A, B1 and C. They are typical alkaline foods and can eliminate the harm caused by large amounts of acidic foods to the nervous system. Eating an appropriate amount of oranges during the exam can make people energetic.

13 Pineapple. It is rich in vitamin C and trace element manganese, and has low calories. Regular consumption can stimulate body fluids, refresh the body, and improve memory.

14 Carrots. It can stimulate the exchange of substances in the brain and reduce the stress of back pain.

15 avocado. Contains a large amount of oleic acid, which is an energy source for short-term memory.

Normal people can eat half an avocado every day.

16 algae. Rich in chlorophyll, vitamins, minerals, and protein, it can improve memory and concentration.

17. Cabbage: rich in vitamin B, which can prevent brain fatigue.

18. Soybeans: Contains lecithin and rich protein. Consuming an appropriate amount of soybeans or soy products every day can enhance memory.

19. Fungus: Contains protein, fat, polysaccharides, minerals, vitamins and other nutrients. It is a good brain supplement.

20. Apricots: rich in vitamins A and C, which can effectively improve blood circulation, ensure sufficient blood supply to the brain, and help the brain enhance memory.

So, when does a person have the best memory? Everyone’s situation is different. There are some differences. You need to find out your best study time. The human brain has certain activity patterns throughout the day. : Generally speaking, the brain has the ability to think rigorously and thoughtfully at 8 a.m.; the most agile thinking ability is at 3 p.m.; the strongest memory is at 8 p.m.; and the reasoning ability gradually weakens within 12 hours during the day. According to these rules, as soon as you get up in the morning, people's imagination is rich, so they should seize the time to capture some inspiration, do some creative work, read Chinese and recite English words part-time. Since the air is fresh in the morning, they should participate in some physical exercise; do some rigorous work in the morning , listen carefully in class and take class notes; in addition to listening to class in the afternoon, do the written homework of the day quickly and accurately; strengthen memory and understanding in the evening, and preview the next day's homework. Arrange some effortless things during the free time at noon and evening
