Smell signals reach brain systems closely involved with emotion and memory, which helps explain why a familiar odor can produce a vivid personal recollection.
What to know
A scent linked to childhood, a favorite meal or a particular place may call up details that you had not been thinking about consciously.
The association is individual: fresh bread might mean a family kitchen to one person and a bakery job to another.
Common mistake to avoid
Scent-triggered memories can be pleasant, neutral or upsetting. Their vividness does not automatically mean they are more accurate than other memories.
