Scientists have for the first time carried out a memory transplant
Transplantation today is no surprise. Doctors have learned to transplant most of the organs and tissues of our body. But what would you say if you were told that can be transplanted not only some part of the body, but also, for example, memory? Until recently, it seemed impossible, but according eNeuro edition of the journal, a team of scientists from the United States have recently been able to do just that.
Some time ago it was believed that memory - it is only the result of electrical impulses generation that occur between cells in the hippocampus, but in 2012 engram neurons were found in this anatomical structure. They were, according to the expert assumption physical "boxes" for memory and memories. Thus, we can conclude that memory is not only electrical but also the chemical nature. Continuing research, a team of scientists from the University of California at Los Angeles, led by David Glantsmenom conducted an experiment in which they were able to convey the memory of one of the simplest organism to another through transplantation RNA from engram neurons.
"The discovery that RNA change from one to another slug passes the memory of the first special, was proof that memories can be stored not only in the synapses, but in another form. Perhaps in the future we will be able to suppress the old memory or record new information directly into the brain. "
their discovery, scientists have made in the course of the study California sea hare (Aplysia californica), large poisonous sea slugs, revealed even more interesting patterns. Scientists have grown 2 colonies slugs. One lived in safe conditions for life, but the second at regular intervals beat current, thereby causing slugs worry about your life. After 2 days, the second column has developed special algorithms of behavior in order to avoid danger. Thereafter, the RNA of the second group from the first transplanted individuals. It turned out that before the calm shellfish began to behave in the same way as their relatives, which beat current. They are experienced and shrank before the next discharge. Thus it was found that the memory can be not only removed, but transferred to another body. The only question is only how to make it safe for the participants in the procedure.
