Autobiographical Odor Memory


Olfactory bulb is probably the queen of synesthesia and odor is the mother of all memories - earlier post. New research here:

"According to a recent review not all of this is just nonsense. This review especially interested me due to it’s creative use of research design and theories about memory. Autobiographical memory across the life span can be divided into intervals across the life span. Over all the age distribution of memories evoked by verbal information is divided in the following phases: childhood amnesia, the bump, and recency or forgetting. Childhood amnesia is why we can’t remember almost anything before the age of 10, the bump is the enormous amount of memories that can be recalled from the ages 10 to 30 years, and recency reflects better retention of events occurring from the last 10 years. More on that
This knowledge is based on verbal cues on personal memories, when comparing verbal cues to odors it’s found that older individuals have a bump with olfactory induced autobiographical memories whereas younger cohorts don’t have this bump."

"
Odor-evoked memorie are more emotional, associated with stronger feelings of being brought back in time, and have been thought of less often as compared to memories evoked by other cues"
