How much "memory" does the human brain have?

Do you know how big the internal brain capacity of your brain is?

Let's take an example, the memory occupied by a movie of about 120 minutes is about a few g.

Then we reflect on the fact that we go through many things in our human life almost from birth to final death.

And in this process, there are many things that we find are almost engraved in our brains and we can never forget them.

So this analysis, it seems that the memory of our brain is particularly large so we will have a question, our human brain capacity is actually how much memory?

In 2014, scientists analyzed the amount of brain capacity in mice. Why did they use mice for the experiment?

One of the most important reasons is that the gene sequence of mice is particularly similar to that of our human body.

Finally, scientists found that the brain of the mouse has 13 neurons, it is through these 13 neurons, scientists found that their memory finally converted down to a surprisingly equal to 1 TB of memory.

That's about 1024 g.

Let's not discuss the difference between the brain cells of mice and human brains, if we calculate it in this way, then one neuron is approximately equal to 0.0769 TB of memory.

In the previous topic, we also mentioned that the number of brain cells in an adult is between 14 and 16 billion, and the number of neurons is roughly estimated by scientists to be about 100 billion.

If we calculate this, we can get that the memory of our human brain should be at least 7.6 billion tb.

What kind of a concept is this? It seems that from the numbers alone, we will not be able to use it all in our lifetime, but this time it makes us question the past.

If there is such a large memory, why in the course of life there are many things we always forget and try hard to think of no way to recover the memory?

For example, do you remember how many times you drank water the day before and how many times you dreamed last month?

These trivial things, we simply have no way to recall.

So what exactly is the cause of this result?

One of the most important reasons is that although our brain has 100 billion neurons, these 100 billion neurons do not only contain the area responsible for storage.

It also includes functions such as organizing, analyzing, and processing as well as cleaning up other aspects of memory.

A report by German psychologists clearly states that about 70% of our memories are quickly forgotten within a few hours.

The brain selectively retains information that it considers to be relatively important.

The information that we consider to be relatively important is repeatedly recalled and repeatedly stimulated to form long-term memories and form fixed pathways of neurons.

This is how what we call long-term memory is born.

Of course, this mode of memory is particularly easy to understand, let's take the example of our school years, did you find that when we first contact a new knowledge?

If not repeatedly stimulated, then within a few days will forget this knowledge.

If repeatedly and constantly stimulated, and constantly consolidate the review, after a long time, this knowledge will become our long-term memory.

And that unimportant information, such as the last month to do a few dreams the day before a few drinks of water, do not stay in our brains for too long.

After a short stay, the information is deleted by some neurons in the brain.

So from these various signs, we can find those who say they have a bad memory, is it possible that their attention is not focused?

It's the lack of concentration that causes certain things to not stay in our brain long enough for the brain to make a deep impression of that information.

It doesn't make the brain think that these things are important information worth staying in the brain's long-term memory.

So some people who are not well rested or who have certain things that bother them tend not to keep their attention very well, and these people can lead to the feeling that their memory is getting worse.

Fundamentally, it is likely that this part of the poor memory of people. It is they who have diverted their attention.
