According to British media reports, Dutch scientists recently announced that they successfully use electric shock therapy to delete the specified memory in the human brain.This breakthrough is expected to help those with depression and in the future with trauma people forget the pain of the past.
Electroshock therapy is also called the shock therapy, it is to point to the doctor with the aid of special equipment and facilities, such as electric shock machine in a short time, with faint, the amount of current stimulation in patients with brain, causing combination in patients with cranial nerve, and to achieve the purpose of a special local treatment.Traditionally, electric shock therapy mainly used in the treatment of psychiatric diseases.Will inevitably be due to the treatment of patients in the process of the whole body twitching,
temporary loss of consciousness, and even long-term memory loss and other symptoms, the treatment in the medical profession is controversial, was reviled as "cruel treatment".However, the "cruel" therapy now achieved a new breakthrough, scope of application is expected to be further widened.
Brain science tells us that once people have some memory in the brain, memory itself will be permanently stored there, will not be easily forgotten.Usually, in order to alleviate the bad memories bring fear and anxiety, the doctor will teach patients to forget the past look forward, through the establishment of new memories to triumph over old memories, but the old memory always firmly rooted in the brain and is activated at any time.
Of scientists, a series of the experimental results show that the memory can be removed from the brain "storage", finally through the brain circuits resurfaced.Extraction in the process of memory in the brain, can undertake artificial "interference", as long as grasp the correct shock opportunity, slight shock on the brain stimulation, can effectively destroy the specified memory, and successfully blocked "memory consolidation" again.
About 10 years ago, the scientists to a rodent brain injected drugs that interfere with the memory consolidation again, on the premise of no damage to other memory, the animal's designated memory is deleted successfully.According to the results of this experiment speculated that if the drug was applied to the brain, in theory, the human brain to store the fear memory will be blocked and deleted or changed, while the other memory can be intact.However, due to the human brain injection drug risk is very big, the related experiment has been no progress.
The success of the Dutch scientists experiment, proves that the memory of the human brain can be artificial
interference.The Dutch neurologists all responsible for the experiment, says we are in more than 40 volunteers carried out experiment, effect is great.The volunteers after the electric shock treatment experiments, have forgotten to ease the pain of the heart in the past, but not affected by any good memories.
Memory can be deleted?To this, the scientists gives a different explanation.Some scientists believe that shock therapy has changed the mode or the metabolism of the brain
blood flow;Some scientists believe that shock therapy in the brain to release certain chemicals against depression.Delete the memory experiment was successful, but people's perception of the problem there are still many blind spots.For example, electric shock therapy is effective for everyone, or apply only to the individual groups?Erase the memory by electric shock therapy is temporary or permanent?Manual intervention brain memory is there side effect?Although this a series of problems remain to be in-depth study on scientists to unravel, however, the "pain" is removed from the life experiences, seems to have is no longer a distant dream.
