为什么蝙蝠、蝴蝶等许多动物长途飞行或迁徙不会迷路?难道它们天生具有方向感或是有辨别方向的非凡本领?许多科学家对此十分迷惑,做了大量研究工作。挪威的科学家曾做过这样的实验。他们选取了一些出生不久的小白鼠作为实验对象,这时的小白鼠尚未睁开眼睛,对外界基本没有感知。科学家在小白鼠的脑中植入电极,一旦小白鼠某部分神经元放电,仪器便能探测到。结果,科学家惊奇地发现,小白鼠在睁开眼的一刹那便能够摸索着爬行,同时大脑中负 Why do bats, butterflies and many other animals fly or migrate long distances without getting lost? Do they have a natural sense of direction or discernible extraordinary skills? Many scientists are confused by this and do a great deal of research work. Norwegian scientists have done such experiments. They selected a few mice born as experimental subjects, when the mice have not opened their eyes, the basic lack of perception of the outside world. Scientists implanted electrodes in the mouse’s brain, once a certain part of the mouse neurons discharge, the instrument will be able to detect. As a result, the scientists were surprised to find that mice were able to groping for crawling when they opened their eyes. At the same time, the brain was negative
