The very small brains of bees are still good enough to recognise different human faces, new research has discovered.

Adrian Dyer, an Australian scientist working at Cambridge University, has trained a troupe1 of bees to recognise different human faces by rewarding them with a sucrose solution when they visited a particular photograph.

Other photographs visited by the seven bees bore only a bitter quinine solution and the bees, despite having brains the size of pin heads, were able to remember the sweet faces, even when the pictures were mixed up and after a gap2 of two days.

Five of the seven made a beeline to the sucrose faces even when the solution was removed, ruling out the possibility that their sense of smell was responsible.

Mr Dyer, 38, of the university's department of plant sciences, said that research had been going on into whether or not the human brain required specialised regions3 to process faces reliably.

"I thought it would be interesting to know whether a miniature4 brain would be able to solve a face recognition5 task," he said, adding that he chose bees as they were more motivated and hard-working than other insects.

  澳大利亞科學家日前發現,盡管蜜蜂的腦部體積很小,但它們卻能夠準確地辨別出不同人的面孔。

  據英國《每日電訊》12月14日報道,英國劍橋大學植物科學系的澳大利亞科學家艾德里安·戴爾對7只蜜蜂進行了識別人的面孔的訓練。戴爾準備了數張不同人的面部照片。當蜜蜂去看一張特定的照片時,研究人員給它們糖水以示鼓勵,而蜜蜂去看其它照片時,只能嘗到研究人員提供的苦澀溶液。

  兩天之后,研究人員將所有的照片混合起來。研究結果令人驚喜,盡管蜜蜂大腦的體積只有大頭針那么大,但它們卻記住了能讓它們得到糖水的那張照片。7只蜜蜂中的5只竟然直接飛到了它們曾被獎勵了糖水的那張照片,而實驗室里的糖水卻早已被研究人員移走,這就排除了蜜蜂是根據對糖味的嗅覺而找到那張照片的可能性。  

  對此,戴爾表示,研究人員之所以選擇蜜蜂而不是其他昆蟲來進行此項實驗,是因為蜜蜂比其它昆蟲更加積極和辛勤地勞動;此外,研究人員還想知道大腦體積如此微小的蜜蜂是否能夠完成諸如識別人類面孔這樣復雜的任務.
