Memory switch was a biological process proposed by James V. McConnell and others within the 1960s. Memory transfer proposes a chemical foundation for memory termed memory RNA which may be handed down by means of flesh as a substitute of an intact nervous system. RNA in response to external occasions, it would also be utilized in neurons to file stimuli. This was proposed as an evidence for the results of McConnell's experiments in which planarians retained memory of acquired info after regeneration. In McConnell's experiments, he classically conditioned planarians to contract their our bodies upon publicity to gentle by pairing it with an electric shock. The planarians retained this acquired info after being sliced and regenerated, even after multiple slicings to supply a planarian where none of the unique educated planarian was present. The identical held true after the planarians have been floor up and fed to untrained cannibalistic planarians, often Dugesia dorotocephala. As the nervous system was fragmented but the nucleic acids weren't, this seemed to point the existence of Memory Wave RNA.

Memory switch through memory RNA is just not at present a nicely-accepted explanation for the planarian habits. Tan, Loh Teng-Hern
