White matter reveals the brain’s age
A new research paper
The Norwegian research news agency, Forskning.no, recently wrote a piece about a new paper we have published. In this paper, we find that participants response times on a computerised task is more stable in young adults compared to older adults, and that this stability is connected to the amount of myelin (fatty tissue responsible for efficient signal transfer of neurons) in the brain. The amount of myelin in the brain increases through childhood and into adulthood, and starts decreasing again around 60 years of age.
The study indicates that means to promote the longevity of myelin in the brain may promote brain health.
