Human Memory

Research conducted at Karolinska Institutet has shed some light on the effect of breathing on the human brain, and this study has some key insights to offer. The study of a possible relationship between breathing and human memory has been under the spotlight for several years. The team of researchers at Karolinska Institutet who conducted the nascent study assert that people who Nose-Breathing likely to have a sharper memory.

Human Memory Retention

The process between memory retrieval and learning takes places when the memory is being solidified or entrenched. They revealed that the mind retains information more strongly when the memory is being consolidated; smells or odours are an example of this. The department of Clinical Neuroscience at Karolinska Institutet stated that this is a first-of-its-kind research that has been conducted in this. Experimental rodents such as mice and rats cannot breathe through their mouth, and hence, it was difficult to conduct such a research earlier.

Research Methodology and Results

A set of twelve participants were subjected to twelve different kinds of smells on two distinct occasions. The participants were successively asked to breathe in through either their mouths or noses for an hour. After this, the participants asked to smell the same odours again, and were asked if they were the same as the ones during the experiment. It was found that when the participants smelt the odours through their nose, their retention of the smell memory was stronger. It is expected that the new research would further open avenues for the growth and development of cognitive and memory studies.
