Early deaf human CI users are often insensitive to sub-millisecond interaural time differences (ITDs); however, with synchronized CIs, early deafened rats learned to lateralize small ITDs near 50 µs.
Training enables adult humans to rapidly adapt their sound localization abilities to unilateral hearing loss by combining different strategies that rely on partially distinct neurophysiological substrates.
Cocktail-party listening performance in normal-hearing listeners is associated with the ability to focus attention on a target stimulus in the presence of distractors.
Computer simulations of interaural time difference decoders show that heterogeneous tuning of binaural neurons leads to accurate sound localization in natural environments.
Principal neurons of the brainstem nucleus comparing sound level at the two ears do not have the slow response properties previously attributed to them, but are instead specialized for fast weighing of excitation and inhibition.
The response from discrete stages of the early auditory pathway can be measured by subtle manipulations to long-form natural speech stimuli paired with deconvolution analysis of electroencephalography data.
