 Dogs make great listeners, and that maybe because man and man's best friend use analogous¹ brain regions to process voices. Researchers collected almost 200,000 samples including humane²-akin vocalizations, as well as environmental noises and silence. They played these clips to 22 people and 11 dogs while the subjects' brains are undergoing functional⁴ MIR scans. Humane brains tuned⁵ the most to vocal³ sounds. Dog brains were most sensitive to environmental noises. But they still have a lot in common. A dedicated⁶ brain area reacted strongly to the vocalizations of their own species, and that area also responded to the voices of the other species. Meanwhile, a different brain region noted⁷ emotional voice with a strong response to cheering sounds like laughter, and a weaker reaction to unhappy noises like crying and waning⁸. The study's in the journal Current Biology. Seems that thousands years of domestication⁹  have made our furry¹⁰ friends sensitive to the same vocal cues as we are. You can confide¹¹ in Fido.
