A new instantaneous blood test for the presence of brain damage

A new instantaneous blood test for the presence of brain damagewas developed. The analysis checks the presence of two proteins in a drop of blood to see if a patient needs to do a CT scan of     When a person hits his head in the fall, during sports games, in a traffic accident or otherwise, he is often taken to a hospital to make a computer tomography - to see if there are injuries or bruises on the brain.  In 90% of people, the tomography is gives a negative result , even if they then find an easy brain damage, for example, a concussion. Consequently, other tools are required for accurate diagnosis of mild brain injuries. In addition, the CT procedure can be ...

Training of empathy: stimulation of neural connections of the brain through a video game

Training of empathy: stimulation of neural connections of the brain through a video game  
 
Human emotions, like any other phenomenon, are governed by certain mechanisms and laws, in this case, the human body, or rather the brain. When you see a crying person, you realize that he is sad (grieving, sad, etc.). Realizing this, you can either pass by, or empathize with this person. The ability to empathize is often called empathy, and it is not a default setting of our brain since birth. It must be developed. Someone is quicker and more natural, someone on the contrary empathy is dulled. Someone may burst into tears while watching the film "Hatiko", and someone and the eyebrow will not lead when ...

The book "The man speaking. Evolution and language " Human language is a unique system of communication that only Homo sapiens have. Why and, most importantly, why did we learn to talk? Why do any of us in the early childhood easily and naturally learn their native language, and learning foreign languages ​​is not an easy task?

Why happiness is so difficult to detect in the brain

Talk about spotology with a researcher in the field of visualization


 
Why happiness is so difficult to detect in the brain  
 
I arrived at a meeting with Professor Chambers in the pretty pub "Cardiff", located next to his office, there to have lunch together, as agreed. He was already waiting for me in the back of the room, and he waved to me when I entered.
 
 
Professor Chris Chambers is a discouraging, calm Australian by age 40. Completely falling under the cultural stereotype, at the meeting he was dressed in a T-shirt and spacious shorts, despite the rain on the street. He also turned out to be completely bald, straight to shine. I've already met ...[/h]

Dialogue of physicists about the soul

"After death there is nothing." A person dies and that's all.
 
- And before death what does a person have?
 
- The body is, for example
 
"Is there a soul?"
 
- No, there is no soul.
 
- And who then has a body?
 
- The body is itself. There are processes in it that allow oneself to feel, evaluate, move in space, and so on.
 
- Well, is the mind there?
 
- The mind is, rather, the property of the body, and not something separate.
 
- That's nice: let's, for example, consider the property of warmth. She, too, not by itself. But in fact it is. She does not disappear. It passes from one physical ...

English grammar as mathematics. Where to start with those who do not have

English grammar as mathematics. Where to start with those who do not haveEnglish grammar is amazing with its simplicity. It is very difficult not to like it: almost everything is logical, structured, understandable, if you know (of course). It's not Russian, where you can say anything you like, but there's a charm in it. Therefore, it always seems to me that people with a mathematical way of thinking nature simply screams in the ear that English should be taught and for them it's easy. Of course, of course, there are all exceptions, without them, but in the general mass everything is logical.
 
Let's say we decided, found some motivation. So how do you begin, where ...

Emotions form the language we use; but the second language helps them bypass

Emotions form the language we use; but the second language helps them bypass  
 
Recently, a taxi driver cut me on the highway. I immediately blurted out a set of curses against this poor fellow. What surprised me was that all these words were in Spanish. I, as a man who grew up in an English-speaking environment, and a Spanish who learned in adulthood, English should have been more accessible. However, I cursed this stranger in Spanish with a Mexican accent, showing the corresponding gestures with my hands.
 
 
Most people are familiar with the sense of how emotions prevail over reason in such situations, but why is it often easier to release steam with a non-native language? Most ...

Why is the human brain so effective?

How massive parallelization raises the efficiency of the brain over the capabilities of AI


 
Why is the human brain so effective?  
 
The brain is a complex device; in humans it contains about 100 billion neurons and about 100 trillion compounds between them. It is often compared to another complex system with huge possibilities for solving problems: a digital computer. The brain and computer contain a large number of elementary units - neurons or transistors, respectively - connected to complex circuits that process information transmitted by electrical signals. At the global level, the brain and computer architectures are a bit similar...[/h]
