1786年著名的意大利解剖学家加尔瓦尼(Galvani1737～1798)在一次实验中偶然发现,挂在铁栅栏的铜钩上的蛙腿在风的吹动下而左右摇晃时,一旦蛙腿碰到铁栅栏,蛙腿肌肉就猛烈地收缩一次。这一现象引起了加尔瓦尼的注意。在此之前,人们已经知道电可以刺激肌肉收缩。加尔瓦尼在仔细排除当时已知电源(如大气的雷电、摩擦起电)的作用后,意识到他发现了新的电源。他大胆设想,动物体内可以产生电,即“动物电”。他认为,青蛙的神经和肌肉带有不同的电荷,故两者之间
In 1786 the famous Italian anatomist Galvani (Galvani1737 ~ 1798) accidentally discovered in an experiment, the frog legs hanging on the copper hooks of the iron fence swinging left and right under the action of the wind, once the frog legs hit Iron fence, frog leg muscles violently contracted once. This phenomenon caught Garvani’s attention. Until now, people already know that electricity can stimulate muscle contraction. Garvani realized that he had found a new power supply after carefully excluding the power supplies known at the time (such as atmospheric thunder and triboelectric charges). He boldly imagined that the animal can produce electricity, that is, “animal electricity.” He believes that the frog nerve and muscle with a different charge, so the two
