Dogs spontaneously process basic numerical quantities, using a distinct part of their brains that corresponds closely to number-responsive neural regions in humans, finds a study at Emory University. “Our work is the first to show that dogs use a similar part of their brain to process numbers of objects as humans do — and we’ve shown that they don’t need to be trained to do it,” says Gregory Berns, Emory professor of psychology and senior author of the study.
