Neural sensitivity to interaural time differences: beyond the Jeffress model.
Interaural time differences (ITDs) are a major cue for localizing the azimuthal position of sounds. The dominant models for processing ITDs are based on the Jeffress model and predict neurons that fire maximally at a common ITD across their responsive frequency range. Such neurons are indeed found in the binaural pathways and are referred to as "peak-type." However, other neurons discharge mini...
متن کاملSensitivity to Envelope Interaural Time Differences at High Modulation Rates
Sensitivity to interaural time differences (ITDs) conveyed in the temporal fine structure of low-frequency tones and the modulated envelopes of high-frequency sounds are considered comparable, particularly for envelopes shaped to transmit similar fidelity of temporal information normally present for low-frequency sounds. Nevertheless, discrimination performance for envelope modulation rates abo...
متن کاملSensitivity to interaural time differences in the inferior colliculus with bilateral cochlear implants.
Bilateral cochlear implantation attempts to increase performance over a monaural prosthesis by harnessing the binaural processing of the auditory system. Although many bilaterally implanted human subjects discriminate interaural time differences (ITDs), a major cue for sound localization and signal detection in noise, their performance is typically poorer than that of normal-hearing listeners. ...
متن کاملEffect of Center Frequency on the Sensitivity to Interaural Time Differences in Filtered Pulse Trains
Some cochlear implant (CI) listeners are sensitive to interaural time differences (ITD) in the temporal fine structure for pulse rates up to 800 pulses per second (pps) [1,2]. The rate limitation in normal hearing (NH) depends on the type of stimulus. For high-frequency filtered transients, the rate limit is within the range 256 − 600 pps, thus lower than in CI listeners [1,2,3]. For pure tones...
متن کاملTuning to interaural time differences across frequency.
Interaural time differences (ITDs) are an important cue for azimuthal sound localization. Sensitivity to this cue depends on temporal synchrony to the waveform (i.e., phase locking) that begins in the hair cells and is relayed to the neural comparators. The synchrony function is low-pass. Therefore, it is expected that neural tuning to ITDs will become narrower with frequency according to a 1/f...
