Abstract: | A weighted reversal potential, E, was defined as: . The concept was shown to be useful in describing threshold phenomena for single and multiple responses by providing explicit criteria which made possible the classification of responses into regenerative or non-regenerative. Within this framework E was also used to analyse the anodic break response and abolishment experiments. Using zero-duration (8-impulse) stimuli, the end of the absolutely refractory period was determined, according to the developed criteria, to be 3·17 t 0·01 ms after the peak of the spike, in the Hodgkin-Huxley model. |
