Brains Built To Cooperate

We are social animals. So you might assume our brains are built to excel when we cooperate with each other, as opposed to when we function in isolation. Now research with another animal supports that notion.
我們?nèi)祟愂巧鐣后w。因此你可能會認(rèn)為我們的大腦在相互合作的時候能夠表現(xiàn)優(yōu)異，而不同于我們獨立做事的時候。現(xiàn)在，在其他動物上的研究支持了這樣一個觀點。

Plain-tailed wrens in Ecuador are famous for duets between males and females. While their song is done cooperatively, with the male and female singing alternate syllables, it sounds surprisingly like one bird singing solo. Scientists who have recorded and analyzed hundreds of such songs decided to capture some of the birds to monitor the brain regions responsible for singing. They anticipated that the birds’ neurons would respond strongest to their own individual voice. But that’s not what happened.
在厄瓜多爾的平尾鷦鷯以雌雄間的二重唱而著稱。當(dāng)他們合作唱歌時，雌鷦鷯和雄鷦鷯交替的唱著各個音節(jié)，這樣的聽覺效果驚奇的就像是一只鳥的獨唱。已經(jīng)記錄 和分析了上百首這樣歌曲的科學(xué)家們決定抓獲一些這種鳥來檢測它們大腦區(qū)域中掌控唱歌的部分。他們期待的是這些鳥的神經(jīng)細(xì)胞對它們各自的聲音的反應(yīng)最強烈。 但事實并非如此。

They found that the birds’ neurons reacted far more strongly to the duet than when they sang their parts alone. The research is in the journal Science.
他們發(fā)現(xiàn)這些鳥在他們二重唱時候的神經(jīng)細(xì)胞比單獨唱自己部分的時的神經(jīng)細(xì)胞反應(yīng)要強的多。這項研究在《科學(xué)》雜志中。

That’s fine for Ecuadorian birds but what about us humans? Well, vertebrate animals all have similar neurotransmitter systems and the brain is organized in much of the same way—so the paper’s authors hold that there is relevance to the human brain. Or at least to those vertebrates who have a tendency to cooperate in the first place.
這樣的結(jié)果對厄瓜多爾的鳥類來說沒什么，那對我們?nèi)祟惸兀考棺殿悇游镉蓄愃频纳窠?jīng)傳輸系統(tǒng)，并且大腦的構(gòu)造方式幾乎是同種方式。所以論文的作者認(rèn)為這和人類的大腦有相關(guān)性?；蛘咧辽賹τ谀切┑谝环磻?yīng)是合作傾向的脊椎類動物來說。
