The Loh Down On Science

Aging Brains

Are you turning 39 this year? Again???

This is Sandra Tsing Loh on the Loh Down on Science.

For you age-fibbers out there, be warned. Scientists at UC San Diego have discovered a way to determine people's age using advanced MRI brain scans.

In a recent study, they isolated and identified over 200 distinct anatomical characteristics within the human brain. That's many more than had previously been thought to exist. They did it by brain-scanning almost 900 children and young adults between the ages of 3 and 20.  

By analyzing and comparing the scans, the team was able to gauge young people's chronological age, plus or minus one year, with 92 percent accuracy. ??Scientists hope this new, noninvasive technique will lead to a greater understanding of brain maturation. Plus, it could provide new baseline standards by which to identify and measure developmental abnormalities.

Like perhaps my fond belief that jeggings will make me look younger.  Not with a brain scan they won’t! Otherwise, oh, probably.
