Wondering where to find the Christmas spirit this holiday season? No need to act like Ebenezer Scrooge – now you know exactly where to look.
Danish researchers say they've found the precise parts of the brain that lit up a brain scan when volunteers who reported feeling Christmas cheer were shown Christmas-time images like holiday street lights, NBC News reported.
Five parts of the brain showed higher activity among that group than the other half, which had more of a "bah, humbug" syndrome, wrote the researchers from the Danish Headache Center and Department of Neurology at the University of Copenhagen in the Christmas issue of the British Medical Journal.
"No eggnog or gingerbread was consumed before the scans," Anders Hougaard and colleagues wrote.
