Researchers from Harvard University discovered that volunteers who were exposed to rose scent as they sleep after studying were better able to recall what they have studied.

The part of our brain that handles smell, the piriform cortex, is right next to that responsible for memory and emotion. Findings showed that odor intensified the transfer of information to the hippocampus, the part of the brain responsible for forming long-term memories.

Another research has shown that it is not just memory that odor can affect. Scientists in Germany discovered that the smell of roses also led to people having pleasant dreams. Yet bad odor can lead to depression and bad dreams.
