Effects 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 کاملSensitivity for interaural time and intensity difference of auditory midbrain neurons in the grassfrog.
The sensitivity for interaural time (ITD) and intensity (IID) difference was investigated for single units in the auditory midbrain of the grassfrog. A temporally structured stimulus was used which was presented by means of a closed sound system. At best frequency (BF) the majority of units was selective for ITD as indicated by an asymmetrically (73%) or symmetrically (7%) shaped ITD-rate histo...
متن کاملSound-intensity-dependent compensation for the small interaural time difference cue for sound source localization.
Interaural time difference (ITD) is a major cue for sound source localization. However, animals with small heads experience small ITDs, making ITD detection difficult, particularly for low-frequency sound. Here, we describe a sound-intensity-dependent mechanism for compensating for the small ITD cues in the coincidence detector neurons in the nucleus laminaris (NL) of the chicken aged from 3 to...
متن کاملThe effects of interaural time difference and intensity on the coding of low-frequency sounds in the mammalian midbrain.
We examined how changes in intensity and interaural time difference (ITD) influenced the coding of low-frequency sounds in the inferior colliculus of male gerbils at both the single neuron and population levels. We found that changes in intensity along the positive slope of the rate-level function (RLF) evoked changes in spectrotemporal filtering that influenced the overall timing of spike even...
متن کاملMeasurement of Detection Thresholds of Interaural Time and Intensity Differences
Localization of sound source in the horizontal plane employs the evaluation of interaural time and intensity differences. The precision of the evaluating system depends on a number of parameters: frequency, overall intensity and deviation of the source from the medial plane. A preliminary psychophysical experiment was conducted to explore the intensity dependence of just noticeable time and int...
