How odors are turned into long-term memories

Neuroscientists have investigated which brain area is responsible for storing odors as long-term memories. Some odors can trigger memories of experiences from years back. A new study shows that the piriform cortex, a part of the olfactory brain, is involved in the process of saving those memories; the mechanism, however, only works in interaction with other brain areas. https://www.sciencedaily.com/releases/2017/12/171222092552.htm
