excitation and inhibition of the reflex eye withdrawal of the crab
... The repetitive responses of isolated crab axons to applied d.c. potentials have been carefully analysed and classified by Hodgkin (1948) and further by Chapman (1966). The motor neuron causing the eye withdrawal belongs to Hodgkin's class 2 in that (1) its frequency of discharge does not follow prec ...
