California sea hare review demonstrates memory transfer through RNA –…


Recollections can be transferred involving organisms by extracting ribonucleic acid (RNA) from a educated animal and injecting it into an untrained animal, as shown in a study of sea snails printed in eNeuro. The research delivers new clues in the research for the physical foundation of memory.

Very long-time period memory is assumed to be housed within just modified connections concerning brain cells. Recent evidence, nevertheless, suggests an substitute clarification: Memory storage might involve changes in gene expression induced by non-coding RNAs.

David Glanzman analyzed the probability that RNA from a skilled California sea hare (Aplysia californica) can be applied to produce an engram — the elusive substrate of memory — in an untrained animal of the similar species. The researchers sensitized some snails with tail stimulation that triggers an involuntary defensive reflex.

Extracting RNA from these skilled animals and injecting it into untrained animals resulted in a similar sensitized reaction. The experienced RNA also amplified the excitability of cultured sensory neurons, obtained from untrained animals, which regulate this reflex. These results increase the possibility that RNA could be made use of to modify memory.
