Study: Successful Memory Transplant Is Achieved In Marine Snail

Memory transfer has been the utter important subject of research in the science fiction for decades, but now it is becoming more like a fact. A team has successfully transplanted the memory from one snail to another by transferring RNA, a type of genetic information.

The snails used in this test were trained to create a defensive response. But when the genetic information is put into the snail, which did not undergo this process, it behaves in a manner as it had been merely injected. The study, published in eNeuro Journal, can open the new ways for searching the physical basis of memory.

RNA is also called as a ribonucleic acid; it is a big molecule intricate in diverse fundamental roles in the living organism, involving the assembly of proteins and the manner in which genes are explained in general.

Researchers gave normal electric shocks to the snail called as Aplysiacalifornica, and then the scientists extracted ribonucleic acid from the snail to which they were giving shocks and inserted into the other marine snails that were not sensitized in the same manner.

The snails who get the injections behave in the manner as if they have been sensitized which they were not and in response showcase a defensive reaction of around 40 seconds.

Prof. from UCLA (University of California, Los Angeles), David Glanzman, said: “The result was, we have successfully transplanted the memory”. He said, “The snails aren’t physically hurt by shocks. These are marine snails and when they sense any danger, they release purple ink to hide, during the research, they released purple ink when they got alarmed.”

The investigators said, “The molecular process and cells of marine snails are similar to the humans, despite the reality that the snails have 20,000 neurons and humans are considered to have 100 billion neurons in their central nervous system.

Prof. David expressed positivity towards the opportunity that greater understanding of memory stacking allows exploring bigger memory-related aspects.
