人睡觉时要做梦,动物睡觉时也会做梦吗?科学家经研究得出了结论:大部分爬行动物不会做梦;鸟类都会做梦,不过大多数种类只做短暂的梦;各种哺乳动物,如猫、狗、马等家畜,还有大象、老鼠、剌猬、松鼠、蝙蝠等都会做梦,有的做梦较频繁,有的则少些;鱼类、两栖动物和无脊椎动物都不会做梦。法国生理学家波希尔·诺夫用猫做了一个很有趣的实验。他用化学和手术的方法阻断了猫的大脑中一个叫做“脑桥”的部位。这样做的结果是,猫梦见了什么,就会按梦境去行动。这只猫经过手术之后,在熟睡中忽然抬起头来,四处张望,然后又起来绕着圈子走,好像在寻找食物。突然它举起前爪,双耳紧贴在脑袋上,对假想之敌猛扑过去。诺夫还把两只动过手术的猫关在一起进行观察,发现原来和睦相处的两只猫,睡着睡着突然打起架来。为了证明这些行为是在睡梦中做出的,诺夫故意在猫身旁撞击物品发出声响,甚至将 Do people have dreams when they go to bed and do they still dream when they sleep? Scientists have concluded that most reptiles do not dream; birds will dream, but most species only have short dreams; various mammals, Animals such as cats, dogs, horses, etc., elephants, mice, squirrels, squirrels, bats, etc. will all dream, some dream more frequently, while others will be less; fish, amphibians and invertebrates will not dream. French physiologist Poser Nove made a very interesting experiment with cats. He chemically and surgically blocked a part of the cat’s brain called the “brain bridge.” The result of this is that what the cat dreamed about would be to act in a dream. After the cat had undergone surgery, he suddenly looked up in his deep sleep, looked around, and then went up and walked around the circle as if looking for food. Suddenly it lifted its forepaws and both ears clung to their heads, pounced on the imaginary enemy. Nove also put together two cats that had undergone surgery to observe and found that the two cats who had lived in peace together fell asleep and fell asleep suddenly. In order to prove that these behaviors were made during sleep, Nov deliberately hit the objects by the side of the cat and made noises.
