Researchers found a structure in our brain that might be responsible for cognitive functions.

 Researchers found a structure in our brain that might be responsible for cognitive functions.  


The fruit flies have astonishing mathematical abilities. And the purpose of that thing is to protect them against things like parasitic wasps. The intelligence of insects is quite a new area in neurobiology. The thing that researchers noticed astonishing mathematical abilities when they researched fruit flies caused a question about those kinds of basically abstract skills "only reflexes". 

Things like communal or social insects require mathematical skills to find parasitic wasps when they attempt to go inside their nest. To protect their nest bees and other social insects require information on how many bees are left from the base. 

And then they must have a recognition protocol to recognize members of their swarms. They need the ability to follow their swarm mates' behavior to avoid the fungus infection. So the insects have only the skills that they need. And they need lots of skills. If we think about the size of their brain. 

Researchers have noticed that fruit flies brains react similar way to threats as the human brain reacts. And that thing gives new abilities and thoughts for modeling reactions in the human brain. 


"Scientists have discovered that human brain signals form swirling spirals on the outer layer of neural tissue, which play a crucial role in organizing brain activity and cognitive processes. This discovery, based on fMRI scans, could advance our understanding of brain dynamics, potentially leading to better computational models and insights into brain diseases like dementia". (ScitechDaily.com/The Missing Link in Cognitive Processing? Scientists Discover Swirling Spirals in the Brain)



The question is are things like mathematical abilities reflexes? Are all our functions and cognitive skills only the series of reflexes? 


Researchers found whirling spiral-shaped structures in our brains. Those structures might be part of the structure or system that controls cognitive functions in our brain. Cognitive function means voluntary learning, and in that process brain selects what kind of information it wants to store in the brain. And that thing means cognitive learning means the ability to send information through the brain. 

During that process, the brain selects the information that it wants to store. The spiral-looking structure makes it possible to drive information through the brain. And during that process, the brain areas can first store that information in themselves. Then those neurons will make a network and decide do they need those memories. 

If they don't need some memories, the brain drives them straight to the garbage. The idea is that cognitive learning or storing data happens when information travels through those neural spirals a second time. If information is not needed, it will not stored in memory cells. 

The number of memory cells is impressive, but that number is limited. Cognitive skills like mathematics require that the brain release the information that they get is important for something. The neural spiral makes it possible for humans. We can also analyze information more effectively than bees. 


The bees can react more effectively than humans, but bees can't make abstract decisions. The abstract decision means that humans can make so-called "empty decisions". When some bee sees something that seems a threat it always jumps airborne. The observation is connected to reflex. Humans have reflex cells. But we also have cells that are learning new things. 

The human reflex neuron protects humans against things like falling or some strike that comes to the face. But cells that are thinking are separated from that system. And that allows humans to learn things like mathematics. 

Fruit flies have astonishing mathematical abilities. Insects require this ability for one thing. They need mathematical abilities and fast calculation to avoid the intruders like parasitic wasps. There is a possibility that the skills of those neurons could transfer to the human brain neurons. And that could improve the mathematical skills of humans. 

Maybe that thing is only some kind of futuristic vision. However, researchers are making tests by using brain simulation to adjust the brain to learn mathematics. Mathematics is the abstract thing that requires that a person follows certain orders. 

Researchers use electric shocks to improve mathematical skills. The fact is that the brain cells are interacting by using certain types of chemicals and signals. In neural models, the same signals and chemicals that make fruit flies able to calculate things are also making human brain cells make the same things.

Thoughts about the movie "Sphere"






http://kimmontaidearvioita.blogspot.com/p/thoughts-about-movie-sphere.html

Kimmo Huosionmaa

"Sphere" is one of the most interesting SciFi-movies, what I have ever seen, and it is the tale of the thing, what comes from tomorrow, and makes all wishes to become true. This is the very good tale to make the nice little movie, but there is one other explanation, what could make those fictional cases, what happened in that movie. In the movie, those scientists face their worst nightmares, and near the end, they rise from the bottom of the sea to empty ship, where they wish that the mysterious "sphere" would leave the Earth.


This movie could also tell about government test, where those scientists would be connected with together by using EEG-machines, and the computer would deliver their thoughts to every member of the team by using brain core stimulation. This kind of fictional test would be made for creating the system, what is connecting human brains straight to computers. And one thing, what those computer specialists must make, is the filter, what cuts off the nightmares from that system.



So in this version, those scientists would be given anesthesia, and then their brains would be connected to the computers. If the system could not filter the fears, they would be delivered to every member of the team, and that would cause the ultimate Virtual Reality experience. If this kind of test would be done in the deep sea, it can be fully controlled. Every information, what is collected will travel thru the Navy, and nothing can be published without permission of the naval officers.


In this fictional test, those scientists can be put in the sleep in the midget submarine by using nitrous oxide, and they would ever be seen, that those people were in some kind of tests. So this kind of thoughts that movie brought in my mind. If we someday will put our brains straight connection with computers, we would make the ultimate computer, what can also create new things. The major problem with the computers is that they cannot make anything new, and they would not have any kind of imagination.


That's why computer's movements on the chessboard and other computer games are very well predictable, what is their biggest weakness. The human would win the computer in most computer games after a couple of training games because the gamer starts to remember the corners, where the opponent is coming. And this thing makes possible to win the computer, and play the game thru. In the same way, the gamer starts to remember the game areas in some action games, and this makes the person, who have tested those paintball tracks before very effective.


Technically we need only EEG-machine, decoder, and the electric shock equipment, what would make the brain core stimulation and allows two ways of communication between human and computer. And if we sometimes would make that machine, we can make the computer, what is so intelligent as we want. We can, in theory, connect even all mankind to supercomputers, but there would be many ethical and moral problems with that kind of advantage. Technology is the very interesting thing, and it would not always follow the moral or even the law.

The story about lost cosmonauts still lives on

https://www.facebook.com/thevintagenews/posts/1962607353814369

Kimmo Huosionmaa

When we are thinking of early years of space flights, we must say that no engineering work comes from nowhere. There must make work with those vehicles, and then there would happen some mistakes with them. And those mistakes confesses, that engineers made their best, and all tests were done. NASA has been dared to show those mistakes, and that might save the lives of American astronauts.


There were actually some secrets in the space capsules, what was not told to the public audience. One was that in some cases are the capsules used inertial navigation system or they were remote controlled, and somebody claims that none astronauts ever made any maneuvers by Mercury or Vostok-capsules. But when we are thinking about the lost astronauts or cosmonauts, we must say that there might be something, what is not told to people. Until NASA:s shuttle orbiter and the cases, when that space plane was used to launch secret military satellites, would the public audience noticed that there were some secret space missions.


There have been found some objects, what looks like skulls from Mars, and somebody has thought that maybe those strange objects were monkeys, what send to Mars for returning test, and then the carbon dioxide pocket have been collapsed and the spacecraft would be destroyed. In this theory, those habitats were sent to there without official permission, and then the permission denied. When we are talking about strange stories about malfunctions of Alexey Leonov space suit during his first spacewalk during spacewalk in Voskhod 2 flight, we must think that those technical problems support the theory, that maybe some cosmonauts were killed, when their space suits or capsules pressure was dropped to zero, or burned into the atmosphere.


I think that this kind of accidents was kept secret from other cosmonauts. Maybe those lost cosmonauts were served in secret space missions, where they flew some secret space recon planes, like "Vostok-type recon satellites", what mission would be targeted and follow the nuclear strikes. Maybe those manned satellites saw use in the early 1960's. When we are thinking about the political atmosphere in the Soviet Union during the Vostok-program, we must say that maybe Yuri Gagarin, was not the first man in the space. That would give the Soviet authorities possibility to close that hero's mouth. The Soviet authorities might not tell that thing to Gagarin, who really believed, that he was the first man in the space.


Maybe his death during the routine flight was suicide because somebody mentioned him about that failed man. There are many rumors about secret space flights to the moon, and if those missions were not made exactly right, can those spacecraft lost in space. And if the spacecraft would miss the orbiter of the Moon, it would go straight to outer space without the opportunity to return. But without evidence, this text is pure fiction. Nothing more.
