Abstract
Recent electrophysiological data obtained from auditory nerve fibers of cats and monkeys have made it possible to construct a model of the peripheral auditory system. A model has been constructed for the purpose of inferrins the neural connections between hair cells and primary neurons. This model is composed of a basilar membrane, hair cells and primary neurons. The neuron characteristics (response area and inhibitory area) of this model are changed remarkably by varying the mode of neural connections between hair cells and primary neurons. In this paper, the conditions which the mode of neural connection must satisfy to fit the physiolngical data are: discussed and the masking effect which is a psycho- physical effect in auditory system is also discussed in connection with the problem of the elevation of threshold of the primary neurons in the presence of masking tone.
