They say that God deprives of reason those whom he wants to punish. But apparently God is capricious like a little child. I know this from personal experience. My wife suffers from Alzheimer’s disease, although before God it is rubbed clean as a whistle. For many years, scientists tried in vain to fight with God for the mind and memory of man. But to defeat dementia they did not manage. Although… Not so long ago scientists have developed a special fabric that they have become implanted in a human brain. And after the first test, the memory test subjects began to improve. Is science found a cure for the salvation of the human brain from the terrible and hitherto incurable disease?
Implanted tissue acts like a pacemaker, implanted in the heart. It sends electric pulsators that help the brain when he tries to get new information, and remain dormant when the brain is functioning normally.
On these experiments reported recently in the journal Nature Communications. Implantable material improves a person’s memory by 15 percent (this refers to the number of words) This equals the fact that losing the human brain from Alzheimer’s disease for two and a half years.
Implantation in the brain is still at the experimental level. Researchers discuss the possible commercialization of this technology. However, it is unknown what will be its broad applicability. The fact that the implant is used only in the epileptics.
Experts warn about potential abuse of this “motor memory”. They say that 15 percent of the surplus memory not so much. However, implantation in the brain increases cognitive (thinking) functions.
Doctors use a similar implantations in the brain to block the normal explosions of activity for many years. We are talking about people suffering from Parkinson’s disease and epilepsy. Professor of cognitive science, University of California San Diego Brady Wojtek says that this method can be applied against dementia.
Implantation is based on years of experiments on decoding the signals sent by the human brain. Recently, this research work was “backed up” by $ 70 million allocated by the U.S. Department of defense to treat soldiers, which the brain was injured during the wars in Iraq and Afghanistan.
A group of researchers led by scientists at the University of Pennsylvania and University of Thomas Jefferson, said that last year she established the connection between electrical surge and revival of the memory. The head of this group of researchers is a Professor of psychology at the University of Pennsylvania Michael Kahana. “Now, when this technology is released out of the box, you can apply different neuromodulation algorithms,” says Professor Kahana.
Another scientist — Professor of neurosurgery, University of California, San Francisco Edward Chang believes that “very similar approaches can be applied to other cases, for example, in the treatment of symptoms of depression.”
The researchers tried a new method of supporting memory in 25 patients with epilepsy. However, they warn that the sample resembles a biased study. Doctors implanted a number of electrodes in the brain, and then expect the onset of seizures that can be stopped by surgical intervention. Many electrodes are implanted in those areas of the brain that are “responsible” for the memory.
Waiting for the results sometimes lasts for weeks, that patients have to spend in hospitals. Scientists cognitivity use this time to test the memory of the patients and record these tests on film. Patients are encouraged to memorize a list of words. Then this list is eliminated, and patients are reminded of its contents. Experimental in the course of these tests, which are repeated several times to recall and remember is not one and the same words. When you turn on implantation patients usually remember the words to all the same 15 percent better.
New technology of implantation of implants in the brain is fraught with certain risks, and opportunities. Professor Kahana said that implantation could further dramatically increase the memory, if it “dig” and not just “warehoused”.
To date, the existing method of brain implant requires implantation of multiple electrodes to establish its functional status. It was an extremely delicate operation that should only be applied in cases of acute deterioration of the patient’s health, not for responding to audience of students,” — grimly joked Dr. Wojtek. “Ideally, we can find less invasive techniques to switch the brain from the lowest to the highest functional status,” he says. I don’t know how to do it, but in the end, we must develop ethical and public policy and to answer questions posed by the new technology of the fight against dementia”.
The road, as you know, begins with the first step. Scientists have made the first step and thought about the second. But, on the other hand, the road by walking. Science does not stand still. Its invasion in the human brain has only just begun. We say “God forbid memory,” but God only otshibaet, punishing this person. Science is our only hope.
