What forms and forms are human memories preserved?

Human memory ability is essentially the ability to store information and give feedback to the brain. The human brain is mainly composed of nerve cells, and the edges of each nerve cell have a number of outward protruding parts, called dendrites and axons. At the end of the axon there is a bulging protrusion called a synaptosome.

The synaptosomes of each neuron are in contact with the dendrites or axons of another neuron. This structure is called a "synapse". Neurons communicate with other neurons through "synapses" and receive information from many other neurons.

The function of neurons to transmit and receive information is the physiological basis of the brain for memory. How many synapses are there on each neuron? Some estimates suggest that there are an average of 30,000 synapses per neuron in the human cerebral cortex.

So, how many neurons does the human brain have? There are about 14 billion of them. The synaptic connections between these 14 billion nerve cells are also astronomical and difficult to express.

Such structural features make the brain a huge repository of information. The human brain's networked system is far more complex than today's Internet. Scientists believe that the capacity of a person's brain to store information is equivalent to the content of a billion books, and even if a person's brain enters ten pieces of information every second for a lifetime, there is still room for other information.

This shows that the memory capacity of our brain is infinite and has a great memory capacity.

Memory is the spiritual body,。。

Know the atom? The space between atoms and atoms, that is the form that cannot be seen, and the spirit is the same as that.

The space between atoms is the spirit of matter that maintains the cycle of atoms and molecules. And memory is constructed by different spirits.

How so??? I don't know...

As for "some precision instruments invented by scientists can connect the brain and know people's memories", I think that at the beginning, they let people sleep, and people who are familiar with them will dream, and the mental fluctuations in your brain in the dream are also different, they write down these fluctuations, and then ask the sleeping person what dreams they have, and check the ripples they have written, and so on and so on, repeatedly, repeatedly. How to extract a memory,It's hard to say here.,You still think about it according to yourself above.,But the above are all made up by me.。。。 However, scientists have recorded brain waves during dreams.

I once watched a movie that said that memories can also be preserved in body cells. It's about a woman who received a heart transplant and dreamed that someone killed her. In fact, the person who provided her heart was killed by her boyfriend.

The activity of the human brain is formed by the propagation of microcurrents or electrons between neurons, and memory is the formation of a fixed circuit between certain microcurrents in a certain order between specific neurons, thus forming a stable memory.

The form of human memory and the way it is preserved are, simply put, the different electrical combinations of n neuronal cells.

Human memory exists in the brain, in the form of a chemical.

Brain cells have memory centers within the brain

"Memory protein" is the material basis of memory, and the fundamental reason why the human brain can remember is because the brain stores specific protein molecules - "memory proteins", and the magical memory function of the human brain comes from "memory proteins".

Memories are categorized by how long they are kept:

1. Instantaneous memory.

Instantaneous memory, also known as sensory memory, refers to the temporary retention of stimulus information in the sensory channel after the stimulation stops acting on people. Information is kept for a short period of time, typically between 2 seconds. The content of instantaneous memory can only be realized after attention and enters into short-term memory.

2. Short-term memory.

Short-term memory is memory that is kept for about 1 minute. According to the experimental studies of L. R. Peterson and M. J. Peterson, the accuracy of recall drops to about 10% after 18 seconds without retelling.

If it will decay or disappear within about 1 minute without retelling, some people believe that short-term memory is also working memory, which is a kind of memory that serves the current action, that is, the short-term extraction and retention of the memory content required by the person in the working state.

There are three characteristics of short-term memory:

1. The memory capacity is limited, according to Miller's research, it is 7 2 blocks. "Chunks" are memory units, and the size of chunks varies depending on the person's knowledge and experience. A block can be a word, a word, a number, or a phrase, sentence, word list, etc.

2. Short-term memory is mainly auditory coding, and visual coding.

3. The content of short-term memory generally needs to be retold before it can enter long-term memory.

3. Long-term memory.

Long-term memory refers to the memory that is retained in the mind for a long time after the information has been fully and deeply processed. From the perspective of time, any memory that is kept in the mind for more than 1 minute is a long-term memory. Long-term memory has a large capacity, and the stored information is also encoded in meaning.

When we usually talk about good or bad memory, we mainly refer to long-term memory.

Although the instantaneous memory system, short-term memory system and long-term memory system each have their own characteristics of information processing, they are continuous and closely related from the perspective of time connection.

Memory Storage:

Instantaneous memory: also known as sensory memory or sensory registration, that is, the response of all information that humans see, hear, and feel in the human brain; Short-term early source memory: It is the process of remembering again through recall review after the first memory, which can generally last 15 to 30 seconds; Long-term memory:

It refers to memories that are more than one minute long, and can be up to a lifetime. There are three levels of brain cellular mechanisms of memory:

Repercussion circuit: human brain nerve cells form a circuit, which is actually more complex and difficult; Synaptic structure: refers to the connection between certain nerve cells that were not originally there, but now forms a new synapse and has a connection; Long-term enhancement:

According to psychologists, long-term memory is accompanied by changes in the anatomy of the brain.

In what form are memories stored in the brain? Let me change this for a moment.

1.Biologically, what happens to the brain?

2.What is going on in the brain from a "conscious" or cognitive point of view?

3.How is information from the internal and external environment of the brain translated so that it can be stored biologically and form an integral part of the brain? In short, how do those seemingly disparate memories relate to each other?

1.Biologically, what happens to the brain?

Biochemical reactions of memory.

The answer to question 1 is as follows:

Now let's take a look at the concept of imprints. This is a theoretical construct that describes memory storage at a biological level. We are still looking for imprints that represent specific memories.

Graphics are interesting because they are both a solution and an abstraction of many problems in memory. When we look at memory in terms of different perspectives such as the organization, neural activity, mental components, etc., of the brain, we can focus on what we can observe and measure. It's an imprint.

As far as we know, memory imprinting is a bit mysterious – there may be specialized "memory imprinting" cells in the brain, or existing neurons may function as memory imprints.

The most surprising thing is that there may not yet be a precise way to conceptualize them. Some experiments have shown that memory is disrupted by the switching of arbitrary neurons in the region of interest. As a result, it is difficult to determine the location of the storage memory components.

According to our current understanding, the memory of a single event is highly dispersed (across multiple brain regions) rather than a fixed location.

2.What is going on in the brain from a "conscious" or cognitive point of view?

Subjective and objective experience of memory

The answer to question 2 is as follows:

3.How is information from the internal and external environment of the brain translated so that it can be stored in a biological way and form an integral part of the brain?

In short, how are these seemingly disparate aspects of memory connected?

Now for the best part - the answer to question 3.

Sorry to spoil you. We don't know how a memory we call a "memory" – your 16th birthday, a college slide, your first day of school, your shoes, movie dialogue, your first kiss, your loved one's face, and so on – came in the form of biological memory storage and mental representations.

This question is still an open question for today's technology.

Key points of the answer] 1) Long-term memory refers to memory that is stored for more than one minute. It stores all the experience and knowledge that we have passed through the spine and provides the necessary knowledge base for all mental activities. The information of long-term memory is stored in the mind for a long time, and there is no limit to the capacity.

2) The storage of long-term memory information is a dynamic process. The form in which information in long-term memory is maintained is an organized knowledge system. This organized knowledge system is important for people's learning and behavioral decision-making.

It enables people to effectively encode new information for better receptivity, and it also enables people to quickly and efficiently extract useful information from it to solve the problem at hand. For example, we need to perceive things, understand language, and solve problems, all of which need to extract all kinds of relevant information from our minds. Depending on how well knowledge systems are organized, the speed of extraction is different, and so is the speed of perception, language comprehension, and problem solving.

3) The changing characteristics of the information during storage. During the storage phase, the quality and quantity of information that has been retained changes. In terms of quantity, the amount of stored information gradually decreases over time; In terms of quality, due to the different knowledge and experience of each person, the way of processing and organizing is also different, and the information stored by people will change in different forms.

The content of the memory is more concise and generalized than the original memorized content, and the unimportant details will gradually disappear. The content of the maintenance is more detailed, more complete, more reasonable, and meaningful than the content of the original knowledge. Some features in the content of the original memory become more exaggerated, prominent, or distorted.

The storage method of human memory is based on the activity of human brain cells, and its principle is like the CPU in the computer, which can be copied and transplanted in the case of human thoughts communicating with each other, just like the principle of 1+1=2 is all transplanted into everyone's brain.

Memory is a type of mental activity of the human mind and falls under the category of psychology or brain science. Memory represents the accumulation of impressions of a person's past activities, feelings, and experiences, and there are quite a few classifications, mainly based on environment, time, and perception.

How are memories formed? To understand the formation of memories, it is necessary to pay attention to nerve cells, because it is here that memories are made.

Regardless of the type of memory, it is basically the same process: a group of nerve cells are simultaneously activated to form a specific form. Thoughts, perceptions, thoughts, hallucinations, etc., any brain function is caused by the same situation.

The human memory system contains many different brain regions: one is the frontal lobe, where long-term memories are permanently stored; the second is the putamen nucleus, where programmed memories are stored, such as driving, cycling, etc.; the third is the hippocampal gyrus, which records and retrieves memories, especially personal memories and memories about space; the fourth is the amygdala, where subconscious traumatic memories may be stored; The fifth is the caudate nucleus, a memory of many human instincts, recorded in the genes.

Even the smallest memory operation involves several neural networks in the brain. For example, the content of an event and the feeling of it are stored in different areas of the brain. The act of such a classification and screening is carried out by the hippocampus, a tiny organ in the brain.

Straddling between the left and right sides of the brain, the hippocampus serves as a gateway for sending and receiving messages, and is responsible for converting "newly received messages" into memories and distributing them to different parts for storage. The hippocampus can be said to be the most critical part of learning, but also the most fickle and unstable part. Once oxygen is insufficient, it is the first place to suffer.

Without Seahorse Hui, we can still learn, but we can't remember it.
