New Memory Theory

A new study from the Salk Institute for Biological Studies has found an interesting correlation between time, neurons, and memories. They have reason to believe that new brain cells “time stamp” the memories of a human associated within several weeks. Their hypothesis is that brain cells encode memories occurring around the same time in the same way. So, if the certain neurons become active during two separate events, a memory linking the two will be formed. Researchers are not disregarding the fact that memories are also associated with smell, sight, and other senses, but they do think that time may also be a very important factor.

These findings may have a very profound effect on research of neurogenesis deficit diseases, a few of which include depression, Alzheimer’s and Parkinson’s. These conditions all have slow brain cell formation and can benefit from this research. Potential therapies include medications, a special diet, and certain forms of exercise to increase the creation of neurons. It will also contribute to the field of working memory. The study helps show the molecular mechanisms in which short-term memory occurs.

The Salk Institute’s “time stamp” theory has been tested by computer stimulation, and studies on mice. It has potential, but still needs a bit more research.
