We thought fake news was bad enough, but now it seems that scientists have successfully implanted a fake memory in an animal, potentially leading the way to human trials.
Researchers were able to reverse-engineer a natural memory by mapping the brain circuits the memory was based on in a test mouse.
Then, they implanted this memory artificially into another mouse by stimulating its brain cells in the pattern of the original memory.
The study, which was described in a paper published in Nature Neuroscience, shows that memories can be artificially created in the absence of any true experiences. The implanted memory was recalled by the test animal and was indistinguishable from a natural memory.
