| 抄録: | This paper introduces a functional model of auditory sound localization based on the interaural time difference (ITD). The signals in the nervous system such as action potentials and synaptic transmission are modeled computationally and these applied to a coincidence detector circuit model to detect ITD. Then impulse trains fluctuating in time are used as input. The incorporated model outputs a spike histogram of which the peak of the envelope will indicate the ITD. The simulation results show that a peak indication the ITD in the azimuth clearly sharpens when using impulses fluctuating in time as input. This suggests that impulse fluctuation does not behave like noise and it can contribute to the detection of ITDs in the temporally redundant process and the nonlinear output mechanism. |
