The researcher Steve Ramirez of Masschusetts Institute of Technology and Xu Liu created the history, the memory with their success will wrong ground is embedded mice cerebra. This one evidence is the simple reaction of this rodent only, but it is tremendous that its are affected. They put this only brushy puppy in box of a metal, the box was frozen, show apparent scared reaction. The reaction of mice resembled getting electrical shock is same, and actually it did not get at all electrical shock.
The graph explains for nerve scientist the interior of cerebrum is run
More absorbing is, their success is considered as a protracted battle. It is suppose, they can identify the nerve related to encode memory not only yuan, and can rescript a kind. This is a feat that makes a person impressive, conduce to the mystery that opens more to be run about memory. Although nerve scientist is considering this kind of possibility all the time for years, but they never had thought this kind of experiment can be truly effective.
This one breakthrough is possible, how to because the research of Oxford discovered short-term memory,change into long-term memory. But the researcher of Masschusetts Institute of Technology takes it into a brand-new direction. Memory stores actually in an area, but certain nerve yuan group of Eng that be called. Ramirez and Liu studied together 2010, devised a kind of new method that explores live body brain, in order to decide specific Eng. Nerve scientists used a kind of new technology that is called smooth genetics, this kind of technology uses the cell that stimulates design of engineering of light stimulus gene to make response to them.
Remembering place area is to use purple number
Scientists are mixed their group infuse of mixture of a kind of biochemistry in the cerebra that special gene transforms mice. This kind of cocktail contains a kind the name is " passageway - red - 2 " sensitive albumen gene. This is gone to by inject dentate time -- the area that the memory in sea horse body is coded. Next they fiber the skull of embedded mice. They acted as the conduit of laser. Researcher discovery, they can be passed to certain nerve yuan infuse laser will activation afresh memory.
To prove to be able to identify specific memory, they activationed to be remembered relevantly with fear. After the experiment ends, check the cerebral tissue of small rat with microscope. The memory related those and specific memory presents green because of the chemical material of infuse. its assimilate to " sky " , over you can see " individual star " . The electrical shock of the Engram of glow and crural ministry is concerned, because this caused fright or scared reaction.
Since knew which letter and fear are concerned, built an experiment to check it. After the same area of cerebra of will cocktail infuse, put mice in box of a metal. This box is safe. This mice is OK 12 minutes are explored below the circumstance that does not have any problems. The following day, it is put in a different box, but got electrical shock however. Researcher assures, the color of these two boxes, appearance and odour each are not identical. The following day, same mice by replace in safe box, and can remember it is safe. But researcher use laser activationed memory of sufficient ministry electrical shock, caused scared reaction.
Nerve yuan the network illumes
To the mankind, is similar procedure OK of the imagination? According to the view of Ramirez: Because principle proof is of existence... between the mankind and technical innovation span exclusively. There are more than 20 labs to having this research on the world today. In fact, group of research of a France is sleeping in the cerebra of mice embedded wrong memory. Bostonian university (center of science of Boston University) nerve (Howard of Director Center For Neuroscience) is rebuilding hard longer, older memory, these experience spread out as the elapse of time.
Have a lot of positive effects, can answer those painful memory from scar hind for instance stimulate an obstacle (PTSD) , depressed with the purify in other drive disease, eliminate them even. The likelihood has application to be in senile and gawkish disease, converse project remembers missing disease. The person that it has medicaments to abuse an obstacle to those sufferring from even is hopeful, let them neglect strong interest. Even if is such, also have inactive meaning. Because our memory is the adhesive that is together our identity hold together, cannot efface is remembered one paragraph, even if be a paragraph of bad memory, graven efface one part him person?
Although painful, inactive memory defined us. Of course, because those are depressed or the obstacle should be stimulated after scar (PTSD) is perplexed and the person with faltering walking may regard his as a kind of desirable part. Today, the target of scientists is not eliminate memory from the technology, it is at the beginning at least such, the means that be promoted with a kind however and is not block up mental health rescripts memory. But latent capacity is existence. Have further effect.
The nerve related to scared reaction yuan be enlightened
How will embedded on witness body false memory change the outcome of adjudgement? In the past, a lot of people are sentenced innocent, appear by what detect at DNA later and by acquittal. Remember embedded likelihood wrongly to bring about a kind of new cruelty the witness distorts form. Picture " pilfer dream space " or " lasting sunshine " such film may become reality. But, if your experience from in the past is medium efface the memory to predecessor, so whether do you acquire the experience about love to also be met subsequently and go?
This involves national control, it is the dominion of one individual thought even. Below totalitarian political power, such program can create false patriotism, the memory of OK even and cleared revolutionary, make them faithful to the country. Accomplish the time that this ability is thought to need 449 years truly. However, advanced research plans American department of defense bureau (DARPA) expresses, use 4 years of time only, can make the embedded thing that gives a kind to be able to alter Ptsd relevant recollection. Theoretic, this kind of technology can use suppress demur.
Meanwhile, new York university (the psychology of New York University) teachs Gary Marcus (proposal of Dr. Gary Marcus) , embedded in person head chip of a miniature, in order to realize man-machine interface, make cerebrum makes engine of a search, increase the memory of people at the same time. Perhaps you can back up the file distorts with preventing. But doesn't it allow a hacker to atttack your cerebra? The ethical dialog with a main field must begin now. Must build superstratum strict formal. However, those are disobeyed likely still in the person that works besides its border. Although this one technology indicated a hope, but must make strong regulations and supervise, encroach human rights and judicatory inequity in order to prevent.
