title: Anteroventral cochlear nucleus models for considering on the missing fundamental.
abstract: Several phenomena, which were made clear by psycho-acoustic experiments, have not electric physiologic evidence data. The missing fundamental phenomenon is one of the phenomena. We try making clear the mechanism how the missing fundamental is produced. By psycho-acoustic experiments and Cochlear models experiments, we investigated its fundamental characteristics in the low frequency range where the influence of spontaneous discharge of primary auditory nerves and the influence of refractory period of primary auditory nerves can be ignored. In order to investigate the mechanism of the missing fundamental in the frequency range where these influence can not be ignored, we have made Anteroventral Cochlear Nucleus models (AVCN models). In this report, Cochlear models - AVCN models is mentioned. And it is also mentioned that the frequency information of the missing fundamental of input signals lower than 900Hz explicitly appeared in the interspike-interval histogram of the aggregated autocorrelogram of output pulse trains from Cochlear models - AVCN models. To confirm it by the perceptual experiments, psycho-acoustic experiments will be carried out in the future.
