Consciousness: RAS(reticular activating system)

Consciousness: RAS(reticular activating system)

 
Some information about "Consciousness" as a result of the findings of experimental research physiological. Or neurological details of which are located in such textbooks. But this is a conclusion to the analysis and synthesis of logic in the form of record only.

(1) The area of ​​the brain stem called the Reticular formation system will act provoking a stream Cerebral hemisphere of the brain's two hemispheres in Los Time. Make New Rochelle area that displays events. And "a sense of when the stimulus reaches a certain level, to make" the feel "and hence it is urging the Los treasured time. It was called the Reticular Activating System abbreviated RAS.

 

RAS is vital to the "feel" it. If it is destroyed To the "unconscious" or "out of consciousness," to that person.

(2) The destruction of the two brain hemispheres and Cerebral hemisphere. People would be "senseless" by the RAS as a regular.

(3) If the blood supply to the brain a few seconds (eg, 7-9 seconds), it would "lose consciousness" as well.

Article (1) - (3), we conclude that.

1. (1) - (2) pointed out that "the emergence of consciousness, Cerebral hemisphere denotes both" not going to RAS ".

2. (3) that it supports. "The birth" of Cerebral hemisphere consciousness is all, of course.

3. If the brain dead and was taken to burn the bier and Consciousness. Or perceive it to be "lost" or that it "is" by changing from. "Another one to the next one," according to the ideas of the science? And how to live in it? That will change, however? What is next? He must be "tested" by the scientists. Further research or knowledge, or the problem is the "afterlife" of their questions and concerns that we have people coming from over there.

4. "awake" due "partly because of" inside "our own bodies.

We see with our eyes actually.

We see from the brain Not seen by eyes why is it so

"We're seeing the brain Not seen by eyes Why is it like that, "This means nothing. Because most people or people in general understand that. Send us because we see eye to look. In fact, The eye is the only device in the exposure. Or a window But a brain What to see Or are perceived to remember and reconstruct the image processor is the brain behind it.

This is what Scientists, ophthalmologists and psychologists all know that. "We do not see with your eyes. But we see with a brain. "

Knowledge of the above. Make today a technology that allows the blind can see again. By bringing the camera from the outside world and then converts the electrical signals that correspond to nerve signals in the brain. The blind receive signals, it can be seen clearly. Although the contrast may not be very high. Soon, this technology has been developed as a person looking from. "The Camera Eye" could be seen clearly than that seen with the eyes. So this technology reinforces that To see the view from the brain through the eye that receives light from the window, however, that the blind can see. Even the eyes are not used to it. Because the brain Occipital Lope in the head after the fine. So when the light fittings to replace the eye, they can be seen again.

 

 So this technology reinforces that To see the view from the brain through the eye that receives light from the window, however, that the blind can see. Even the eyes are not used to it. Because the brain Occipital Lope in the head after the fine. So when the light fittings to replace the eye, they can be seen again.

But on the other hand, even though the eyes of them were fine, but the brain Occipital Lope severe concussion. He became blind in an instant, as if we hit hard off the back of the head. Our eyes are not blurry focus. If severe Can not see it
So the fact that "We do not see with your eyes. But with a brain "is true also quite attractive. Therefore, if we want to "see opportunities" that the more we do not need to adjust the eye. But we should adjust the brain. The only one part of the brain called the Reticular Activating System, or RAS, which we'll talk about next time.
