Dogs may not be able to count to 10, but even the untrained ones have a rough sense of how many treats you put in their food bowl. That's the finding of a new study, which reveals that our canine pals innately understand quantities in much the same way we do.

That's the finding of a new study, which reveals that our canine pals innately understand quantities in much the same way we do. The study is "compelling and exciting," says Michael Beran, a psychologist at Georgia State University in Atlanta who was not involved in the research. "It further increases our confidence that [these representations of quantity in the brain] are ancient and widespread among species." The ability to rapidly estimate the number of sheep in a flock or ripened fruits on a tree is known as the "approximate number system." Previous studies have suggested monkeys, fish, bees, and dogs have this talent. But much of this research has used trained animals that receive multiple tests and rewards. That leaves open the question of whether the ability is innate in these species, as it is in humans. In the new study, Gregory Berns, a neuroscientist at Emory University in Atlanta, and colleagues recruited 11 dogs from various breeds, including border collies, pitbull mixes, and Labrador golden retriever mixes, to see whether they could find brain activity associated with a sensitivity to numbers. The team, which pioneered canine brain scanning (by getting dogs to voluntarily enter a functional magnetic resonance imaging scanner and remain motionless), had their subjects enter the scanner, rest their heads on a block, and fix their eyes on a screen at the opposite end (see video, above). On the screen was an array of light gray dots on a black background whose number changed every 300 milliseconds. If dogs, like humans and nonhuman primates, have a dedicated brain region for representing quantities, their brains should show more activity there when the number of dots was dissimilar (three small dots versus 10 large ones) than when they were constant (four small dots versus four large dots). Eight of the 11 dogs passed the test, the team reports today in Biology Letters . Intriguingly, slightly different brain regions lit up in each dog, likely because they were different breeds, Berns says. "These findings support our understanding of the Approximate Number System; previously, these effects had only been demonstrated behaviorally in dogs, so this is an important contribution to our understanding of canine cognition," says Krista Macpherson, a canine cognition researcher at Western University in London, Canada. And, she adds, the study is likely to be of interest to dog trainers, because it suggests dogs may pay more attention to the number of items—as a reward, for example—presented rather than the volume of items. Dogs and humans are separated by some 80 million years of evolution, Berns notes. So this discovery "provides some of the strongest evidence yet" that most mammals are born to count, if not to do higher math. *Correction, 19 December, 12:25 p.m.: Because of a misunderstanding, the quotation from Krista Macpherson was incorrectly reported. It has now been corrected.

We talk a lot about sob-inducing movies, but personally, I don’t think enough attention is paid to the power of music that makes you cry, from Adele ballads—duh—to offerings from Mitski and Enya (trust me on that one). After the emotional few years we’ve all had, it’s more important than ever to let yourself feel your feelings, as trite as that may sound, and sometimes, you need a little help. Here, in no particular order (other than the one they occurred to me in), are 23 of the very best songs to curl up and weep to.
