Ever wondered how you retain memories of your favourite dish cooked by your mother or your partner's scent? Scientists have found that a brain area is responsible for creating memories from smells as well as retaining those memories even years later. The study showed that the piriform cortex -- a part of the olfactory brain that distinguishes smells -- is involved in the process of saving those memories. It is known that the piriform cortex is able to temporarily store olfactory memories. We wanted to know if that applies to long-term memories as well said Christina Strauch from the Ruhr-Universitaet-Bochum
