[Brain researcher Laura Cuaya] and her colleagues designed an experiment with 18 volunteer dogs — including her two border collies — to see if they could differentiate between two languages. Kun Kun and Odín were used to hearing Spanish; the other dogs Hungarian.
The dogs sat still within an MRI machine, while listening to an excerpt from the story The Little Prince. They heard one version in Spanish, and another in Hungarian. Then the scientists analyzed the dogs’ brain activity.
Attila Andics leads the lab where the study took place and said researchers were looking for brain regions that showed a different activity pattern for one language versus the other.
“And we found a brain region — the secondary auditory cortex, which is a higher level processing region in the auditory hierarchy — which showed a different activity pattern for the familiar language and for the unfamiliar language,” Andics said.
“This activity pattern difference to the two languages suggests that dogs’ brain can differentiate between these two languages. In terms of brain imaging studies, this study is the very first one which showed that a non-human species brain can discriminate between languages.”
