Neuroscientists around the globe have been researching on the relationship between smell and memory.
Some have believe that damaged sense of smell can tell dementia. Being on the lookout, they have unraveled clues.
The small brain region (amygdala) which is responsible for the processing of sensory information is close to the hippocampus.
The most recent researches reveals that people with a good spatial memory may be better at detecting smell.
Any Information related to time and space is located in the anterior olfactory nucleus. This is the area of the brain that is in charge of the development of Alzheimer’s.
Karolinska Institutet in Stockholm, Sweden, discovered that breathing through the nose, rather than the mouth, improves olfactory memory.
The first author of this paper is Artin Arshamian, a researcher at the Department of Clinical Neuroscience with the Karolinska Institutet.
Arshamian and his team asked understudied male and female. He asked the participants to learn 12 new smells on two occasions. After each of the “sniffing session,” the participants were told to breathe either through their noses or through their mouths for 1 hour.
When the hour elapsed, the participants smelled the old 12 scents along with a lot of new ones. These participants then decided which of the smells were old and new.
