Dogs make great listeners.
狗是最好的傾聽者。
And that may be because man and man's best friend use analogous brain regions to process voices.
而這也許是因為人類和人類最好的朋友都使用類似功能的大腦區域對聲音進行處理分析。
Researchers collected almost 200 sound samples, including human and canine vocalizations, as well as environmental noises and silence.
研究人員們采集了大約200份聲音樣本，其中包含了人類和犬類的發音，以及環境噪音和靜默時的背景聲音。
They played these clips to 22 people and 11 dogs while the subjects' brains were undergoing functional MRI scans.
他們隨后對22名人類以及11只狗播放這些音頻片斷，收聽的對象們還在同時進行著大腦功能性核磁共振掃描檢測。
Human brains tuned in most to vocal sounds.
人類大腦對大部分聲音都能接收到。
Dog brains were most sensitive to environmental noises.
而狗的大腦則對環境噪音比較敏感。
But they still had a lot in common.
但人類和狗類大腦反應還是有許多共同點存在的。
A dedicated brain area reacted strongly to the vocalizations of their own species.
各自物種的腦類中都有一個專門區域對本類別的發聲作出強烈的反應。
And that area also responded to the voices of the other species.
而該區域也能對其它物種的聲音做出反應。
Meanwhile, a different brain region noted emotion in a voice, with a strong response to cheery sounds like laughter and a weaker reaction to unhappy noises like canine whining.
同時，另外一個不同的大腦區域是通過聲音對情感進行了標注的地方，會因為像大笑這種歡呼聲有強烈的反應，而對像犬類哀號悲鳴這樣的不愉快噪音則沒有過強的反應。
The study is in the journal Current Biology.
該研究已在《當代生物學》雜志上發表。
Seems that thousands of years of domestication have made our furry friends sensitive to the same vocal cues we are.
貌似幾千年的馴化工作使得我們這些有毛的朋友們對一些我們人類所特有的聲音特點比較敏感了。
You can confide in Fido.
