Researchers found that dogs and humans have the same “audio receiver area” in their brains. This part of brain is responsible to understand and interpret voices of dogs and humans.
“Dogs and humans capturing method are similar,” said Andics Attila, a researcher MTA-ELTE Comparative Ethnology Research Group from Hungary.
“In the beginning of human’s ancestor, humans’ brains are equal to dog’s brain these days. But human's brains have been changed along with the changing of time.” said Andics.
During a research, scientists tested 11 dogs; Golden Retriever and Border Collie, together with 22 humans. Dogs and humans have to generate their natural voice, such as howling, barking, crying, and laughing. At the same time, the researchers observed their brains reactions using MRI equipment.
As a result, the scientists found that dogs could create strong voices as what they always do, like howling and barking. While humans could create strong voices as what they always do, such as laughing and crying. But humans and dogs seemed to responding each other.
However, this research only done to two sort of dogs, Andics suggested the next research must be wider. The research would show the differences of brains shape and other factors. (livescience.com/straightoff)
