Scientists have uncovered that the brain makes two copies of every event They were surprised to find the brain makes two copies of every event - one for the present and the other for the long-term. Experts say the findings from the Riken-MIT Centre for Neural Circuit Genetics in the US along with a team from Japan were "beautiful and convincing." Two parts of the brain are involved in collecting and storing personal experiences. Short-term memories are collected by the hippocampus while the cortex retains long-term memories. Dr Amy Milton, who is a memory researcher at Cambridge University, said the study was "beautiful, elegant and extremely impressive". She added: "I'm quite surprised. "The idea you need the cortex for memories I'm comfortable with, but the fact it's so early is a surprise. "This is one study, but I think they've got a strong case, I think it's convincing and I think this will tell us about how memories are stored in humans as well." The discovery was first made back
