Reason to forget the elderly
U.S. scientists said they have found a reason to forget with age, is the presence of a brain signal to discourage nervous.
He favored the researchers in their study, published their results in the magazine «Nature» British could get rid of this forgetfulness, and indicated that they intend to carry out more experiments with the elderly in this direction, and become signals between nerve pathways in the brain are weak with the progress of the age of rights, because of the lack of signals released by nerve cells in the Age of the applicants, leading to forget the old man of things often, as the researchers under the supervision of my mother Ernstn University School of Medicine «Yale». The researchers looked for the first time changes in the nerve cells in the cerebral cortex, the part responsible for the perception.
And these cells send nerve Asttharat permanently to keep the information «live», which helps the person to keep things that used on a daily basis, such as remembering where the car keys, for example. The base is also the living memory and abstract thinking processes and hide complex ideas is appropriate, but necessary to update this fast memory continuously. The researchers studied the rate of energy signals of nerve cells during the experiments they conducted on animals, they found that the firing of nerve cells in animals older signs are slowly during the process of remembering, and it is possible to increase the frequency of these signals if the conditioning center for chemical nerve cells to become close to the animals small.
The researchers found that much of what is known molecules «CNN. State. Um. B »which weaken frequency signals accumulate in the frontal lobe of brain aging, and that these molecules open the channels in the walls of neurons, allowing the infiltration of charged particles« ion », and weakens the signal carrier frequency of information the brain. The researchers noted that they intend to do field trials on the substance Joinvassin effective researchers believe that a good effect to improve the ability to remember.
