Our brain tells us what to do, how to react, how to think and what to say.
It is our brain who remembers the faces of strangers wandering in the streets and protects us from worry.
We rely on the brain to survive and to learn anything.
But this is the body part about which much is still secret.
Every year, new information is revealed by science about this amazing organ.
In 2019, there are amazing discoveries revealed about the brain.
Some of the results are staggering. Here we’ll try to share about the amazing discoveries of the human brain in 2019.
The Strange World of Dreams
People experience a lot of emotions during sleep, even anger, this was revealed in a medical study.
Researchers try to analyze brain activity to see if an individual sees dreams as being angry.
They examined brain parts that help control the expression of emotions and solve problems.
In the areas called the frontal lobes, activity before and after sleep revealed that an individual could also see anger or an angry dream.
When we are resting, the brain releases alpha brain waves, but many times the waves emit much, reducing the functions of the cerebral area that helps control anger.
Isolation and effects on the brain in Antarctica
The effects of isolation on the human brain have been reported in a study that looked at 9 individuals who had been alone in Antarctica for more than a year and discovered that their brains had become smaller.
Researchers compared their brain scans and discovered that the volume of the brain, such as the hippocampus (a part that helps to improve learning and memory), decreased during that time.
Additionally, the protein levels of a protein called BDNF decreased in the brain, which helps in the development and survival of new nerve cells and is essential for new brain connections.
Now researchers are trying to find sources that can help prevent loneliness from shrinking in people living alone.
A group of scientists are stunned to find that some people in the world can still smell, when the most important part of their brain is missing which smell.
This section, called Olfactory Bulbs.
It is located in the front of the brain that analyzes information about nasal odor.
Researchers discovered this through a brain scan of a 29-year-old woman who could smell like normal people, although olfactory bulbs were missing in her brain.
Later, the same thing revealed in 2 other women who did not have this part of their brain but still could smell it.
However, scientists did not know how this magical ability came to be in women, but they believed that another part of the brain plays the role of olfactory bulbs, and it also shows the brain’s ability to mold itself.

Some animals find their way by using an unseen gravity field and now it is known that some people are capable of sensing the planet’s magnetic field.
It is yet not clear how they do this.
In a March 2019 study, scientists scanned the brains of 34 people who were instructed to sit in a dark test chamber with an artificial magnetic field.
Brain analysis revealed that 4 out of 34 people reacted strongly to the magnetic field moving from the northeast to the northwest, but this did not happen in other directions.
All four of them had a brain wave indicating that the brain was detecting a potentially magnetic signal.
It is unclear why some people react to the magnetic field while others do not.
It is also unclear how the brain recognizes these signals,
it has been revealed in the past that numerous small magnetic particles in the human brain potentially play a role in this regard.
Eliminating the fear of death
Every human being has to die one day, but it is our brain which proves to be a shield against our idea of death.
The mind does not allow the idea that one day we will die.
By the way, the brain uses predictive information to predict similar situations in the future, and it also means that the brain can predict that you will die one day.
But Scientists discovered that information about our death thought was lost in the brain process.
For this purpose, the response of the brains of 24 people was observed when the words associated with death were shown to them.
The scale of their brain activity showed that the brain’s predictive mechanism of death of an individual stop working.
It is unclear why this happens, but scientists think that the awareness of his death can create fear in a person that will prevent him from moving forward in life or taking risks for various tasks.
Scientists have long known that brain activity varies greatly during sleep,
for the first time in 2019, it was discovered that when humans sleep, nerve cells flow out of the blood as soon as they sleep and a fluid-like liquid begins to flow, it cleanses the brain.
Scientists at Boston University for the first time succeeded in taking pictures of the brain’s process during sleep, and they hope it will help to understand mental disorders.
Care fluid is found in the spinal cord of the spinal fluid (CSF) and is believed to clear toxins from the brain, leading to dementia.
Professor Laura Louis, who is on the research team, said that this is a dramatic effect; CSF does it during sleep, something we did not know before.
During the study, 13 healthy individuals aged 23 to 33 years were examined with a brain MRI scanner.
Besides, scientists monitored a variety of activities in the brains of volunteers and examined the nerve cells by electrodes, while MRIs showed the presence of oxygen-rich blood in these nerve cells.
Another type of MRI research team also examined CSF activity in the brain.

THEY noticed that during sleep, electrical signals, also known as delta waves, appeared and after a few seconds blood began to flow out of the head and CSF began to fill his brain.
Researchers say we were shocked to see this because it was very shocking.
Alzheimer’s (the most common type of dementia, have less or weak delta waves resulting in impaired blood circulation in the brain, and cleaning of CSF is not complete.
As a result, toxic protein begins to accumulate and memory is impaired.
This part is my most favorite in the list of Amazing discoveries of the human brain in 2019.
The Brain’s amazing ability to mold itself
The brain has an amazing ability to adapt or mold itself accordingly, which is expressed in a small group of people whose half the brain died as a result of childhood epilepsy.
Despite deprivation of over 50% of the brain, the brain functions continuously.
During the Research, scientists analyzed the brains of six people aged 20 to 30 years, 50% of which were lost from 3 months to 11 years and were compared to the brains of healthy people.
Brain scans have proven that brain parts work together in the same way that a healthy brain does.
They also discovered that different brain parts work together despite deprivation, and this proves that the brain is capable of molding itself despite large-scale deprivation.
Specific storage for language learning
Your brain needs storage to master a language.
One Study found that the brains of average English-speaking adults require 12.5 million bytes or 1.5 megabytes of storage for details related to this language.
The brain needs more storage for the meaning of words than just syntax for so many details of the language.
In good conditions, an adult can remember one to two thousand bits of their native language a day, and in the worst case, it may be 120 bits.
‘Living’ the dead brain
Scientists claim to have been able to restore circulation and cellular activity to the brain of the dead animal several hours after their death.
In this experiment, a group of scientists said that the cell’s death span is long and, in some cases, it may be possible to suspend or reverse.
Researchers have developed a brain X-ray system for the analysis of dead brains that insert synthetic blood into the brain arteries.
The fluid was injected into the brains of 32 dead animals 4 hours after their death and left for 6 hours, and scientists discovered that it protected the brain cell structure, reduced cell death rates. And some of the cellular activities were restored.
Scientists say that it did not appear in the brain, which is something that happens during a conscious state, which scientists ask, what does it mean then to claim that the brain is alive? Currently, this research is done on animals and not on humans.
In some patients with a coma or anesthesia, symptoms of ‘latent consciousness’ appear.
One study analyzed the brain waves of more than a hundred patients who lost consciousness due to a traumatic injury and discovered that every one of the 7 patients had a very deep brain activity within a few days of the injury. Patterns or occult consciousness when they are called to shake hands.

This indicates that the patients understand the instructions but are unable to move, after one year, 44% of the patients showed signs of latent awareness which was active for at least 8 hours daily.
Fourteen % of patients did not show any early symptoms of this latent awareness, and the researchers said that the patients in whom the symptoms appeared were more likely to recover than other patients.
