Neuroscientists from the University of Budapest used brain scanners to investigate the brain activity of dogs when they heard their owner's voice, and specific words spoken by the owner. The dogs heard both meaningful and nonsense words spoken in praising and neutral tones. They found that dogs respond to actual words and not just the tone in which they are spoken, which suggests dogs do comprehend the words. Their work appears in the latest issue of Science.

When the scientists analyzed the brain scans, they saw that—regardless of the trainer's intonation—the dogs processed the meaningful words in the left hemisphere of the brain, just as humans do, they write this week in Science. But the dogs didn't do this for the meaningless words. "There's no acoustic reason for this difference," Andics says. "It shows that these words have meaning to dogs."

From the paper's abstract:

During speech processing, human listeners can separately analyze lexical and intonational cues to arrive at a unified representation of communicative content. The evolution of this capacity can be best investigated by comparative studies. Using functional magnetic resonance imaging, we explored whether and how dog brains segregate and integrate lexical and intonational information. We found a left-hemisphere bias for processing meaningful words, independently of intonation; a right auditory brain region for distinguishing intonationally marked and unmarked words; and increased activity in primary reward regions only when both lexical and intonational information were consistent with praise. Neural mechanisms to separately analyze and integrate word meaning and intonation in dogs suggest that this capacity can evolve in the absence of language.

    Whether or not you are a dog owner, if you have 10 minutes, i would recommend you read it, it's hilarious.
