Washington: The main consciousness of human existence, which includes sight, hearing, dreaming, imagining, pain or happiness, fear, fear, love and more. But exactly where is it located in the brain? Scientists and medical professionals have long been upset with this question. A recent study is providing new information in this domain.
Neuro scientists examined blood flow, electrical activity and magnetic activity in the brains of 256 volunteers in 12 labs in the United States, Europe and China as they saw various images that reduce awareness in trying to identify areas of the brain. Measurement monitored mental activity in different areas.
Researchers found that consciousness may not be born in the “smart” part of the brain – in front of the areas where the thought is, which gradually increases the process of human evolution – but also in the sensory zone in the back of the brain that acts on the voice and sound.
“Why is any of it important?” The Alan Institute’s Neuro scientist in Seattle asked Christopher Coach, a leader of a study published in the journal Nature this week.
The coach said, “If we want to understand the sub-reservoir of consciousness, which he has, the adolescent, pre-linguistic baby, the other quarter fetus, a dog, a mouse, a squad, a revenue, a bee-we need to identify the basic mechanisms in the brain, along with both imaginary reasons.”
In the study, articles were shown images of people’s faces and different items.
The coach said, “The way consciousness feels to see the drawing of a toaster or the face of a jerk. Consciousness is not like the behavior of this feeling, for example, pressing the button or saying, ‘I see a burning.’
Researchers experienced two leading scientific ideas about consciousness.
Under the global neuronal workplace theory, consciousness does the front of the brain. The main part of the brain does, which contains significant pieces of information and then broadcast widely throughout the brain. Under integrated information theory, consciousness comes out of various parts of the brain through interaction and cooperation as they work to integrate collectively working information that is consciously tested.
These results did not square with any ideology.
“Where are the signs of neuronal feet of consciousness in the brain? Very dilapidated, are they in front of the cortex – the outer layer of the brain – such as the prefrontal cortex, such as the global neuronal workplace theory is predicted?” The coach asked.
It is the prefront cortex that makes our species uniquely human, moderating high -ranking academic processes such as planning, decision -making, reasoning, personality, personality, and social behavior.
“Or to footprints, posterior cortex in the back letters of Cartex?” The coach asked. Later cortex is comprised of regions where hearing and vision processing.
“Here, the evidence is decisively in favor of the poster cortex. Either the information about the experience of consciousness was not found in the front or it was weaker than behind. The idea supports that Frontal lobes are critical for intelligence, decisions, reasoning, etc., they are consciously not imagined, not in view.”
However, this study did not identify so many contacts that consciously in the back of the brain to maintain integrated information theory.
There are practical applications in the brain to gain a deep understanding of consciousness mechanics.
The coach said it would be important for doctors to be treated with patients with coma or plants or patients with irresponsible awareness syndrome, when they wake up but do not cause mental traumatic injury, stroke, cardiac arrest, high amounts of drugs or other causes.
The coach said, “If the patient lasts for more than a few days without the signs of rehabilitation, then the clinical team starts a conversation with the nearby family,” Did they want this? ” “The coach said.
Of such patients, 70 to 90 % die as it has been decided to withdraw life -retaining treatment.
“However, we now know that a quarter of the condition/irresponsible awareness syndrome of a coma or plants is conscious of the condition of a coma or plants,” the coach said, citing a research published last year in the New England Journal of Medicine.
