We created a false memory in mice by optogenetically manipulating memory engram–bearing cells in the hippocampus.
„If you want to grab a specific memory you have to get down into the cell level. Every time we think we remember something, we could also be making changes to that memory – sometimes we realise sometimes we don’t,” Dr Liu explained.
„Our memory changes every single time it’s being ‚recorded’. That’s why we can incorporate new information into old memories and this is how a false memory can form without us realising it.”
