摘要
Abstract
Objective To discuss the relationship between stimulating pulse width and the product of pulse width and current threshold. Methods First,based on the expression about pulse width and the current threshold of single nerve and electrically evoked compound action potential( ECAP ),the expression which describes the relationship between pulse width and the product of pulse width and the current threshold is derived. The result shows that the relationship between them is linear. Second,judging from the results of Shepherd and animal experiment,the linear relationship can not precisely express the relationship between them,because there is an extreme point on their relation curve. Results Research result shows that,because of the non-linearity of the experiment results,there are some discrepancy between the experiment results and the expression which is derived from the expression about pulse width and the current threshold. Conclusions Because of the discrepancy and the nonlinearity of experiment results,we should further discuss the influence of electrical stimuli on auditory nerve and propose an accurate expression.关键词
