Document Summary
People have been interested in animal electricity for a long time. Luigi galvani and alessandro volta (picking around in frogs). They sapped a frog leg and saw that it t witched, so they concluded that electrical activity that had something to do with animal behavior and movement. Ramon y cajal using golgi stain to stain cells in the nervous system. It"s from this work that we have what we now know as the neuron doctrine: individual cells called neurons actually underlay everything about the function of the nervous system. Alan hodgkin and andrew huxley: theory of the action potential. Studied what is known as the giant squid axon, which has to do with its escape response. Mylenation is one of the methods of speeding up action potential propagation along the axon, so squids don"t have mylenated axons, their solution to the same challenge of propagating the signal fast is having really big, fat axons.
