MRI scans reveal how our brains enter a sleep-like state when we step out of the area

It really is possible for your mind to become completely blank! MRI scans reveal how our brains enter a sleep-like state when we step out of the area

  • Scientists looked at the brains of 36 participants while they were in an MRI machine
  • People have found that they mind going empty about five to seven percent of the time
  • Scans showed how their brains entered a sleep-like state as they were divided into regions

If you are talking to your other half, and he suddenly stares into space, try not to be offended.

A study found that sometimes people’s minds naturally go blank, as their minds seem to automatically shut down their thoughts.

The researchers looked at 36 people who were put into an MRI machine and asked them to describe their thoughts.

People found that their minds became blank about five to seven percent of the time.

The results of the scans showed that their brain enters an almost sleep-like state, with constant activity in all regions, rather than changing activity in the different brain regions associated with thought.

Researchers now believe there is a good evolutionary reason to divide into regions when focus is best — to stop our brains from being fatigued.

Scan results showed their brain entering an almost sleep-like state during a mind vacuum (MB), with consistent activity across all regions, rather than altered activity in the different brain regions associated with thinking.

Forgetting is a form of learning, study claims

Instead of our memories degrading over time, forgetting is actually an active form of learning that helps our brain access more important information.

This is the conclusion of experts from Trinity College Dublin and the University of Toronto, who said that the “lost” memories did not really disappear, but became inaccessible.

They explained that memories are permanently stored in clusters of neurons, with our brains determining which ones we reserve access to and which are irrelevant to lock away.

They said these choices are based on environmental feedback, which in theory gives us flexibility in the face of change and make better decisions as a result.

If the findings are correct, they could lead to new ways of understanding and treating memory loss associated with the disease – as seen, for example, in Alzheimer’s patients.

‘Our study is the first to find that people’s minds are naturally empty, and this is caused by a specific activity in the brain,’ said Dr Athena Demirtzy, senior author of the study from the University of Liège in Belgium.

People who turn away are often judged for not listening properly or being lazy, but people really can’t help it, and we now think it’s a good thing.

“Having too many thoughts can leave brain cells overwhelmed, so this might be a way to conserve energy.”

The study, published in the Proceedings of the National Academy of Sciences, looked at people who received regular incentives to report their thoughts while in an MRI machine.

Every minute or so, after hearing a beep, they chose from four options on the screen to describe their thoughts.

Most of the time, people were thinking about their own environment, like the sound of the MRI machine, the experience, like how long it would take, or something else, like what they were planning to have for dinner.

But people also sometimes chose the option of showing that their minds became blank, meaning that they could not remember what they thought, or that their minds felt empty of ideas.

When this happened, the researchers saw a pattern of overall brain activity across about 100 separate brain regions.

The constant flow of signals between brain cells, with one signal not being amplified more than any other, is similar to what we see when people are deeply asleep.

The study, published in the Proceedings of the National Academy of Sciences, looked at people who were instructed regularly to report their thoughts while in an MRI machine (a stored image).

Brain scan results suggest that when people’s minds go blank, it may be because they literally have no thoughts, or alternatively because they can’t access or remember their thoughts.

More research is needed to determine exactly what’s going on (SUBS – please keep it up).

“We know from previous studies that their minds daydream about half the time,” Dr. Demirti said.

“But the mind that empties is different, and may be of use to you.

“I certainly don’t worry so much anymore when I get carried away in a meeting, as the brain seems to have a good reason for it.”

Illustrated: MRI that depicts the magnetic fields used to see inside the body

Magnetic resonance imaging (MRI) is a type of examination that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.

An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the examination.

An MRI scan can be used to examine almost any part of the body, including the brain, spinal cord, bones, joints, breast, heart, blood vessels, and internal organs — such as the liver, uterus, or prostate gland.

The results of an MRI scan can be used to help diagnose conditions, plan treatment, and assess how effective previous treatment has been.

Most of the human body is made up of water molecules, which are made up of hydrogen and oxygen atoms. At the center of each hydrogen atom is a smaller particle called a proton. Protons are like tiny magnets and are very sensitive to magnetic fields.

When you lie under a powerful scanner magnet, the protons in your body line up in the same direction, the same way a magnet would pull on a compass needle.

Short bursts of radio waves are then sent to specific areas of the body, knocking the protons out of alignment. When the radio waves are turned off, the protons are reorganized. This sends radio signals, which are picked up by receivers.

These signals provide information about the exact location of the protons in the body. They also help to distinguish between different types of tissues in the body, because protons in different types of tissues reorganize at different speeds and produce distinct signals.

In the same way that millions of pixels on a computer screen can create complex images, signals from millions of protons in the body are combined to create a detailed picture of the inside of the body.
