How much capacity does a human brain have? What is the maximum number of things that can be memorize

I don't think the human brain can be directly compared with the capacity of the hard disk, but the things stored in it are a bit similar, there are fast and slow, the human brain sometimes stores some junk files (it depends on his education, and the environment he is in), the computer has a little advantage that it can directly delete the junk files, but the human brain cannot.

I remember watching a TV show that said that if you develop five percent of the potential of your brain, you can memorize all the textbooks from elementary school to college.

Theoretically, the potential of the human brain is limitless, and theoretically one can write down anything one has seen, even if it is just a glance. But in reality, most areas of the brain are unexplored, and that's what scientists are now studying: how to harness the brain's powerful memory function.

For a very small number of people, they can remember almost all the details of their lives, but for most people, it's actually a benefit, as having this ability can make their lives much more burdensome. Remembering the details of life means that no matter the trivial things in life, they will remember and cannot forget, especially some painful memories that will make their lives more difficult.

In a sense, forgetting is the way our brains organize memories, so the most relevant memories can be evoked at any time, and normal forgetting can be identified as a safety mechanism for the brain not to be oversaturated. Forgetting is very normal for human beings, if you want to achieve the effect of not forgetting at all, you can achieve such a purpose through some electronic devices, because electronic devices are not only convenient to store, but also very convenient to extract, many things in life The brain can not be completely remembered, and through the storage function of electronic devices can make our life and work more convenient.

The capacity of the human brain is infinite, and it follows the principle of using it in and out, and there is no such thing as running out. For example, the most famous memory method, the memory palace. It can help a person remember thousands of numbers and thousands of different faces in a very short period of time, and at the same time can use them at any time.

Distinguish the difference between subtle things, and the error rate is very low.

It is said that the human brain has a storage capacity of 12,000 billion grams. So it's up to you to imagine how much you can remember, but memories are forgotten, and when you remember new things, old, unused memories are gradually forgotten.

If quantified, it should be trillions of terabytes of capacity. However, this space is not complete, it belongs to the storage memory, and it has to support other complex calculations.

The brain volume is about 1300 to 1500 ml. Brain capacity is perfectly memorable for all things in a person's life, but because the brain only develops a small part of it, people tend to forget things that are not very important. It should be said that for a person's life, the memories that the brain can store are unlimited.

The average person can memorize 500 million books, and the brain cells of normal people are about 14 billion 15 billion, but less than 10% are developed and utilized, and most of the rest are in a dormant state. After the age of 30, the brain cells are dying at a rate of 100,000 per day, although this is insignificant for the brain's 15 billion brain cells, but if the brain cells that die are developed and functional, it will inevitably affect the brain efficiency and will be dull and dull.

1. There is no upper limit to the storage of the human brain. The human brain is extremely complex, every second, the human brain is undergoing 100,000 different chemical reactions, and the number of cells in the brain is more than twice that of the world's population. The most amazing memory in the world is a memory master from Japan, who can remember 42,905 decimal places of pi, and he tells everyone that memory can be improved through improvement, which means that there is no upper limit to human memory, but we are not developing the brain to the maximum.

2. Nowadays, science and technology are becoming more and more developed, many people think that computers will replace human brains in the future, and scientists feel that this is not realistic, because the human brain is much more complex than computers, and computers are still developed by human brains, and scientists want to solve the brain is a world problem, in other words, it is difficult to solve the mystery of the brain with human brain thinking. Therefore, the brain is far more complex than the computer, and even if the storage capacity of today's computer is large, it cannot compare to the storage capacity of the human brain.

3. Scientists have found that the storage capacity of the brain can be developed, but people cannot develop 100% of the brain in their lifetime, and only less than 10/10 of it is developed. Even Albert Einstein, who invented the atomic bomb, only developed 13% of his brain, and it would be quite terrifying if the human brain was fully developed, and I don't know what humans would develop.

People can store information indefinitely, depending on how much your brain has been developed. Some people can't hide much, and they can't remember a little more. And some people are still in the purpose no matter how many things are, no matter how long the past is. That is to say, human capacity is dynamic and multifactorial.

According to brain scientists, the human brain has four times the capacity of the Library of Congress. Brain scientists believe that the human brain is forever dissatisfied.

If the human brain were to be used in its entirety, all the knowledge in the world from ancient times to the present would still not be enough to fill the brain.

The human brain is a truly extraordinary organ, and so is human memory. Even if you think you have a bad memory, you still have a natural miracle: this organ system is able to easily store things and recall them in a split second.

So, how much memory capacity does the human brain have? Can it be measured in common computer notation?

Attempts to estimate the storage capacity of the kilogram of brain in the skull date back at least half a century, when the development of electronic computers provoked a comparison between the relatively weak memory of humans and their much larger brain size, which one speculates must be large.

In a 1956 lecture at Yale University in the United States, computer scientist John von Neumann (the father of the computer) proposed an estimate of the capacity of the human brain at about 35 trillion petabytes – an astronomical number, even by the standards of today's computers.

Later estimates were based on the assumption that the 100 billion connections between brain cells would be stored in about 40 million megabytes, which is also huge, but not comparable to von Neumann's data.

After reviewing the estimates, Professor Ralph Merkle, a computer scientist at Georgia Tech, pointed out that these results have previously made more or less unreliable assumptions about how the brain stores information. He thinks a better estimate might come from experiments that more directly measure the storage capacity of the brain.

As an example, he cites the results of a study conducted in the mid-1980s by Thomas Landauer and his colleagues from Bell Labs, in which subjects were asked to recall different forms of information at different times. As a result, the level of recall is surprisingly consistent, and when that translates into the total amount of data that the brain can store over a lifetime, the result is 200 megabytes. This figure is much less than von Neumann's estimate, but the result is much more accurate.

As Professor Merkle puts it: "While this result may be a blow to our sense of self-worth, it shows that we only need slightly more hardware than we have now to create a device with human skills and capabilities – if we know the right way to organize the hardware." ”
