UC Davis finds brain sizes are growing

A new study by UC Davis shows that our brains are growing. Researchers found that brain sizes have steadily grown over the last 90 years. In fact, data shows that the brain surface area of people born in the 1970s is 15% larger than those born in the 1930s. So, what does that growth spurt mean for our overall health? NBC Bay Area’s Audrey Asistio spoke to Dr. Charles Decarli, the lead author of this study, for some insight.
