Model of Type 3 firing in neurons (Clay et al 2008)

An ionic model for Type 3 firing in neurons (Clay et al 2008) Some neurons fire only once in response to a sustained depolarizing current pulse, type 3 behavior. One example, surprisingly, is the squid giant axon. The Hodgkin-Huxley (HH) model of this preparation fires repetitively for these conditions – type 2, a result that is not observed experimentally as shown in the above paper. Changing one parameter of their model of IK is sufficient to mimic the result.
