Science Magazine: Creating a False Memory in the Hippocampus

See on Scoop.itNeurovium: Neuroscience at the intersection of Philosophy, Logic, Biology & Physics

Science Editor: “Being highly imaginative animals, humans constantly recall past experiences. These internally generated stimuli sometimes get associated with concurrent external stimuli, which can lead to the formation of false memories. Scientists identified a population of cells in the dentate gyrus of the mouse hippocampus that encoded a particular context and were able to generate a false memory and study its neural and behavioral interactions with true memories. Optogenetic reactivation of memory engram–bearing cells was not only sufficient for the behavioral recall of that memory, but could also serve as a conditioned stimulus for the formation of an associative memory.”

Very interesting…This is a good first step in transferring memory from one to another, for good or bad. If one day we can erase memory and rewrite it (which we will do at some point), what are the limits? on whom and how it should be practiced? who should have the permit to do it? Would we be able to detect "real" memories from "implanted" ones? Can we recognize that part of the memory are erased?
