A Simple Modification Of The Hodgkin Huxley Equations Explains Type 3 Excitability In Squid Giant Axons

This paper describes an unusual finding from a well known preparation in neuroscience - squid giant axons. Specifically, the cell fires once and only once in response to a sustained depolarizing current pulse, a result Alan Hodgkin referred to as Type 3 in a classic paper on crustacean axons published in 1948.
