.So how do human memory neuron cells operate in our brains? The initial memory cells were born because our brains absorbed some information and knowledge. This is the initial form of memory, a weak and pitiful cell body. This process is called neurogenesis in the professional terminology of brain science. If we don't use it in time at this time, it will be quickly killed by the forgetting mechanism of the human brain, causing us to forget that information or knowledge point. In many cases, this speed is as fast as the blink of an eye. For example, in your daily life, you often see something in front of you and forget about it in the back. On the contrary, as we continue to use this memory and associate it with other memory cells in the brain, it will establish solid connection channels with other cells. The name of this channel is a synapse. This matter was first proposed in 1949 by Canadian psychologist Donald Hebb, known as the father of neuropsychology and neural networks, known as Hebb's law. Finally, when you use this memory more and more, it will have a strong correlation with many memory cells, and the channel will become more and more stable. The outside of this cell and the synapse will be reinforced with very solid myelin. , this thing can speed up the transmission of certain memories by a hundred or a thousand times, which is equivalent to replacing cement roads with highways, and replacing tricycles with maglev trains. This process of strengthening memory channels is called myelination. This is the activity process of memory and neuron cells in our brains. From this, you can know that the essence of memory is the process of myelination.

The unit of memory is different from any other unit of measurement. It has a unique property: the chunks are dynamically changing and always normalized. A letter is a chunk when it stands alone, it is a chunk when it is combined with several other letters to form a word, and it is a chunk even when the word is combined with other words to form a phrase. This is a bit like a Russian matryoshka doll. The essence is that many small units can be packed into one large unit, but no matter what the content of this large unit is, it is still one unit and only occupies a certain memory capacity of your brain. One memory; many of these large units can also be packed into a larger unit, but it is still one unit and only takes up one memory. Cognitive psychology calls this magical phenomenon chunking, and the unit of memory is named after chunking. So what's the use of knowing this? Do we need to rely on the word "chunking" to break down the essence of learning? Xu Su, are you kidding me? I'm not kidding you, just these two words can break it. When you know that the unit of memory is a chunk, and when you know that the characteristic of a chunk is that it changes dynamically and is always consistent, you will know a truth: knowledge has convergence.

Most people think that knowledge is divergent, and think that every piece of knowledge that pops up in front of them is new knowledge, so they always feel that there is too much knowledge, too many articles, too many books, and they cannot remember it at all; but the real situation is, Knowledge is convergent! Even from the perspective of human brain memory, all knowledge can eventually be converged and summarized into a few lowest-level rules of origin!

We obtain the meaning of new knowledge by incorporating it into the existing knowledge system.
