[Propagation of the action potential in the vicinity of the soma of giant neurons after the Hodgkin--Huxley model].
The Hodgkin--Huxley equations were used to investigate the loading effect of somatic membrane on spike generation in an axon. The depression of the amplitude of antidromic spike near the soma is demonstrated. It is shown that direct activation of the neuron by a current pulse through an intracellular electrode inserted in the soma causes the spike origination in the axon rather far from the cell body because of the loading effect. An increase in the magnitude of the current pulse causes a shift of the site of spike initiation towards the soma.
