Making a Word Map Better Together

Hello! My name is Lampobot, I am a computer program that helps to make a Word Map. I know how to count, but so far I don’t understand how your world works. Help me figure it out!

Thank! I became a little better at understanding the world of emotions.

Question: push through Is it neutral, positive, or negative?

Network passive

In 1997, researcher Gordon Schulman analyzed the results of nine brain studies using a scanner - and made another discovery.

Schulman hoped that his work would help to detect a neural network, activated by the concentration of mental effort.

But he found something completely opposite - a network that activates when the brain is not occupied with anything specific.

Shulman suggested that when the volunteers' brain transitions from a state of rest to a state of solving its mental problem, the brain, activity will increase.

In fact, it was found that certain areas of the brain at the same time just became less active.

Shulman came to the conclusion that during periods of apparent inactivity of the brain, its individual areas are more active than in periods of concentration on specific tasks.

It took some time for the theory of a never-sleeping brain to spread in the scientific community.

Neurobiologists stubbornly continued to believe that neural connections in the brain that were not activated at a particular point in time were temporarily disconnected as unnecessary.

In 1998, a reviewer of a scientific article by Marcus Reichl - now one of the leading experts in this field - criticized his work, saying that the hypothesis of brain activity at rest was definitely based on mistakes made in experiments, and therefore could not be true.

However, over time, the situation has changed. To date, nearly 3,000 scientific papers on the activity of the brain in a state of rest have been published.

Some scientists even oppose the use of this term, indicating that in reality there is no question of any peace of the brain.

They prefer to use the term “passive brain network” (SPSR), which describes the totality of areas of the brain that remain active during periods of apparent mental inactivity.

The question is why an unoccupied brain is so active. There are several theories on this subject, and so far scientists have not reached consensus.

Perhaps various areas of the brain are thus trained for subsequent collaboration.

Or the brain continues to idle, like a car engine, to instantly turn on at the right time.

There is another possible explanation - wandering the mind and playing back events that occurred during the day play an important role in sorting memories - according to the latest research, even rats tend to "dream in reality".

It is also known that the wandering mind is often carried into the future. We are starting to think about what we will eat for dinner or where we will go next week.

SPRM includes three main areas of the brain that are responsible for visualizing the future.

It can even be assumed that our brain was programmed to think about the future as soon as it had a free minute.

Moshe Bar of Harvard Medical School believes that looking into the future has a very logical explanation.

In his opinion, thanks to daydreaming, we have "memories of the future" - about events that actually did not happen.

In the future, we can use these “memories” as a guide to action, if our dreams ever come true.

For example, many air passengers will ever think of how they will act in the event of an accident.

Bar believes that when a person really gets into an accident, memories of hypothetical scenarios that he had thought up earlier could help him choose the right behavior strategy.

However, it is very difficult to examine the brain at rest.

A number of experts in the field of cognitive psychology indicate that researchers cannot know for sure whether the volunteer lying in the scanner is in a state of complete disconnection from reality.

In fact, a person can focus on the sounds made by the scanner and what is happening in the room where he is.

Therefore, a fairly large range of questions related to the wandering mind, answers so far received.

For example, are our wandering thoughts different from unsuccessful attempts to focus on work, from thoughts that arise when trying to calm the mind?

Everyone dreams in his own way.

However, there is some progress in this area. According to a scientific paper published this year, each of us experiences a state of brain inaction in a slightly different way.

Researchers studied scanned images of the brains of five people, specially trained to memorize the details of the "wandering" of their own mind and the subsequent detailed story about them by sound signal.

Scientists have found significant differences in the dreams of experimental subjects.

In September of this year, researchers from Oxford University studied brain scans of 460 participants in the Human Connect project to determine the relationship between the active parts of the brain at rest.

The results of the study also indicate differences between the subjects - this time related to the volume of life experience and skills acquired over the years.

As it turned out, the strength of the connections between different areas of the brain depends on the development of memory, level of education and physical endurance.

It is possible that in the process of wandering the mind, connections between different parts of the brain are preserved in case we urgently need to use them.

In the theory that the brain is never completely at rest, perhaps the answer lies to the question that has long tormented scientists - why does the brain need 20% of the energy produced by the body, although five percent would be enough to maintain obvious mental processes?

Marcus Reichl calls the remaining 15% "dark energy" of the brain - it is possible that it is spent (in whole or in part) to maintain brain activity at rest.

The opening of the SPRM can also change our understanding of the nature of the mind.

We all know how difficult it is to calm the mind. New scientific evidence gives us the opportunity to suggest that, in fact, wandering the mind can be useful - despite the fact that they do not allow us to finish the work on time.

In other words, perhaps we should stop treating the idleness of the mind as something bad.
