It can be shown in experiments using Aplysia when "it is possible to transplant memory to another individual"

David Glanzmann and others who are professors of biology at the University of California, Los Angeles have succeeded in the experiment of "transplanting memories to another individual" that seems to come to fiction such as comics, movies, novels. Grantsman et al. Are experiments using Aplysia, which means that they succeeded in transferring memory from one individual to another.

The research team of Mr. Grantsman et al. Is formed based on the DNA of the cellRibonucleic acidExperiment showed that transplantation of memory is possible by transplanting RNA (RNA) to another individual. The research teamJumbo ApricaMultiple groups were prepared and divided into "stimulus-giving group" and "non-stimulus group", and then stimulated regularly to the tail of the apricot of the stimulus group. Initially, this group of Aplysia seems to have taken a defensive posture for only a few seconds with a single stimulus, but as a result of continuing to give stimulus, as a result of once giving a stimulus it keeps the defensive posture for about 50 seconds It has been reported that it began.

Next, the research team collected RNA from Amehushi, which began to take a defensive posture. And I injected RNA into the neck of the American Aplysia who do not give stimulus. Then, it has been confirmed that the Aplysia injected with RNA has taken a defensive posture for 40 seconds only when stimulation is given, even though it has never been stimulated before, but by transplantation of RNA Experiments have shown that memory is transplanted.


Many researchers have reported that "long-term memory is a phenomenon between neuronsSynapse"I think that some researchers have a negative view on Mr. Grantsman's research. However, Mr. Grantsman says, "If our memory is preserved in synapses, our experiment will never work," he insists that this experimental result is the answer.

The research team said "This research is in the early stagesAlzheimer's diseaseTreatment to regain some of the patient's memoryPost traumatic stress disorderThere is a possibility that it may lead to a new therapy of the disease, "suggesting the possibility of being applied to human therapy in the future.

However, the contents shown in this research are merely the fact that we can transplant memory of Aplysia merely. Therefore, Mr. Glanzmann as the next step, "We are going to experiment whether we can transplant memory by transplanting RNA even in animals with complex memory like mouse."
