A functional circuit model of interaural time difference processing.
Inputs from the two sides of the brain interact to create maps of interaural time difference (ITD) in the nucleus laminaris of birds. How inputs from each side are matched with high temporal precision in ITD-sensitive circuits is unknown, given the differences in input path lengths from each side. To understand this problem in birds, we modeled the geometry of the input axons and their correspo...
متن کاملA functional circuit model of 1 interaural time difference processing
16 Inputs from the two sides of the brain interact to create maps of interaural time difference (ITD) 17 in the nucleus laminaris of birds. How inputs from each side are matched with high temporal precision 18 in ITD sensitive circuits is unknown, given the differences in input path lengths from each side. To 19 understand this problem in birds, we modeled the geometry of the input axons, and t...
متن کاملA physiologically based model of interaural time difference discrimination.
Interaural time difference (ITD) is a cue to the location of sounds containing low frequencies and is represented in the inferior colliculus (IC) by cells that respond maximally at a particular best delay (BD). Previous studies have demonstrated that single ITD-sensitive cells contain sufficient information in their discharge patterns to account for ITD acuity on the midline (ITD = 0). If ITD d...
متن کاملEffects of interaural intensity difference on the processing of interaural time difference in the owl's nucleus laminaris.
Interaural time and intensity differences (ITD and IID) are processed independently in the owl's auditory system. This paper examines whether this independence is established in nucleus laminaris (NL), the first site of ITD processing. A plot of discharge rate against time difference (ITD curve) is sinusoidal in NL. The ITDs that produce the peaks are called the most favorable ITDs, and those t...
متن کاملAn adaptable ellipsoidal head model for the interaural time difference
Experimentally measured head-related transfer functions reveal that the interaural time delay varies from person to person. Furthermore, it is not constant around a cone of confusion, but can vary by as much as 18% of the maximum interaural delay. The major sources for this variation are shown to be the shape of the head and the displacement of the ears from the center of the head. A simple ell...
