A unique experience of showing scenes directly to the brain while ignoring the eyes

Amsterdam, The Netherlands: A unique experiment has been performed to visualize scenes directly on the brain while ignoring the eyes. The two monkeys were not shown a scene on their blindfolds, but were fitted with special electrodes (electrons) in their brains that signaled the letters.

 In this way, the clearest (high resolution) image is obtained by grafting a brain. 

Interestingly, the eyes were not used in any way during this time. Pieter Roelfsima, a scientist at the Netherlands Institute of Neuroscience, called it good news. 

People with complete blindness can certainly gain some sight from it. Earlier, some people have been able to see black and white scenes by reaching the scenes with the cameras mounted on the head and the patch in the retina, but the quality of the picture is very poor.

 In 2013, the 60-electrode Argus Two graft was approved for regular use in the United States. 

Keep in mind that technology such as Argus II is useless for patients whose visual nerves and veins (optic nerves) have been destroyed. Instead, 

Professor Pieter chose an important part of the brain (the visual cortex). It works like a cinema screen in our brain. Each of these areas acts as a visual field. 

If an image in the shape of A is given on the electrode here, then in principle the viewer will also understand it as A and will feel the same. 

But if the lightning is placed only at the level of the visual cortex, it does not yield those results, but the viewer can feel only a few points. 

For this, the experts used silicon electrodes like a needle 1.5 mm long and attached them to the inside of the cerebral cortex. It had 16 rows of 64 electrodes. When they were implanted in two race monkeys, each monkey had a graft of 1,024 electrons. 

The monkeys were first shown 16 letters of computer English and their eye movements were noted. Then they closed their eyes and were shown the letters mentally, then the movements of their closed eyes were exactly the same. 

That is, they were looking at the image formed on the brain, not seeing a letter with their own eyes. 

However, this technology is difficult for humans because the visual cortex is very deep in the human brain. Then over time, the electrodes may become defective, but this technology proves that it is possible to show a scene directly instead of with the eyes.
