Spiking models for level-invariant encoding

Frontiers in Computational Neuroscience, 2012
Levels of ecological sounds vary over several orders of magnitude,but the firing rate and membrane potential of a neuron are much more limited in range.In binaural neurons of the barn owl, tuning to interaural delays is independent oflevel differences ...

Single-sided deafness and unilateral auditory deprivation in children: current challenge of improving sound localization ability

Journal of International Medical Research, 2020
Interaural time difference and interaural level difference signals are insufficient in patients with single-sided deafness (SSD). This insufficiency leads to an absence of sound localization abilities and a decrease in speech intelligibility in noisy ...

Population rate-coding predicts correctly that human sound localization depends on sound intensity

eLife, 2019
Human sound localization is an important computation performed by the brain. Models of sound localization commonly assume that sound lateralization from interaural time differences is level invariant.

Neural Dynamics of Phonological Processing in the Dorsal Auditory Stream [PDF]

, 2013
Neuroanatomical models hypothesize a role for the dorsal auditory pathway in phonological processing as a feedforward efferent system (Davis and Johnsrude, 2007; Rauschecker and Scott, 2009; Hickok et al., 2011).

Noise reduction of coincidence detector output by the inferior colliculus of the barn owl [PDF]

, 2006
A recurring theme in theoretical work is that integration over populations of similarly tuned neurons can reduce neural noise. However, there are relatively few demonstrations of an explicit noise reduction mechanism in a neural network.

Interplay between low threshold voltage-gated K+ channels and synaptic inhibition in neurons of the chicken nucleus laminaris along its frequency axis

Frontiers in Neural Circuits, 2014
Central auditory neurons that localize sound in horizontal space have specialized intrinsic and synaptic cellular mechanisms to tightly control the threshold and timing for action potential generation.

Virtual Audio - Three-Dimensional Audio in Virtual Environments [PDF]

, 1996
Three-dimensional interactive audio has a variety ofpotential uses in human-machine interfaces. After lagging seriously behind the visual components, the importance of sound is now becoming increas-ingly accepted.

Virtual Reality and Sound Localization [PDF]

, 2012
Psychoacoustics is the scientific study of sound perception. Within this field, Virtual Reality is a technique that uses two synthesis speakers to simulate a sine tone coming from anywhere in open space.

Developmental fine-tuning of medial superior olive neurons mitigates their predisposition to contralateral sound sources.

PLoS Biology
Having two ears enables us to localize sound sources by exploiting interaural time differences (ITDs) in sound arrival. Principal neurons of the medial superior olive (MSO) are sensitive to ITD, and each MSO neuron responds optimally to a best ITD (bITD).
