The fiber that conducts the nerve impulse is a tubelike structure. Its operation can be studied by squeezing the contents out of the giant axon of the squid and replacing them with various solutions ...

First, they chose the right model system. The squid axon offered technical advantages due to its size and relative simplicity, with only two types of voltage-gated conductances. Second ...

SEVERAL investigations of the effects of temperature on the squid giant axon have been made, but as yet the changes of the conduction velocity associated with altering the temperature have not bee ...
