Spending just a few months in Antarctica can shrink your brain #Fact #Shorts

If you ever take a trip to Antarctica, be sure to do as much socializing as you possibly can, and come up with stimulating ways to keep yourself busy. Research published in the New England Journal of Medicine in Dec. 2019 explained that "brain imaging in eight polar expeditioners before and after 14 months of isolation showed that the volume of the hippocampal dentate gyrus was lower than that in controls." IFL Science notes that "researchers believe the changes in the brain they observed are the result of … environmental monotony and prolonged isolation." #shorts #fact
