Therefore, they were not atoms, but a new particle, the first subatomic particle to be discovered, which he originally called "corpuscle" but was later named electron, after particles postulated by George Johnstone Stoney in 1874. Source: Internet
When pressure is applied and the corpuscle is deformed, mechanical stimulus is transferred to the axon, which fires. Source: Internet
