Scientists Explained Why Smells Revoke Vivid Memories

Our brain combines smell with the information about space and time to form episodic vivid memories, according to a recent research, published in the journal Nature Communications. These findings can help improve sniff tests for the Alzheimer’s disease.smells are associated with vivid memories

In the course of the study, a team of researchers examined the role of the anterior olfactory nucleus (AON) in memory using a mouse model in a range of experiments. They discovered a previously unknown neural pathway between the hippocampus and the AON.

Study co-author Afif Aqrabawi says: “[The findings demonstrate] that we now understand which circuits in the brain govern the episodic memory for the smell. The circuit can now be used as a model to study fundamental aspects of human episodic memory and the other odor memory deficits seen in neurogenerative conditions.”

Quiet Rest after Learning Will Help to Memorize Details

A new study from the United Kingdom suggests that a simple quiet rest, just for 10 minutes, may help to memorize new information in fine detail.quiet rest

To study this effect, the researchers designed a memory test to assess the ability to keep finely graded information. For the experiment, the researchers took the information on memorizing from 60 young male and female participants whose average age was 21 years.

Michael Craig, a researcher from the Heriot-Watt University in Edinburgh, United Kingdom, says: “This new finding provides the first evidence that a brief period of quiet rest can help us to retain more detailed memories.”
