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.
Biology Letters published the results, which suggest that a common neural mechanism has been deeply conserved across mammalian evolution.
“Our work not only shows that dogs use a similar part of their brain to process numbers of objects as humans do — it shows that they don’t need to be trained to do it,” says Gregory Berns, Emory professor of psychology and senior author of the study.
“Understanding neural mechanisms — both in humans and across species — gives us insights into both how our brains evolved over time and how they function now,” says co-author Stella Lourenco, an associate professor of psychology at Emory.
Such insights, Lourenco adds, may one day lead to practical applications such as treating brain abnormalities and improving artificial intelligence systems.
Lauren Aulet, A PhD candidate in Lourenco's lab, is first author of the study.
