Mechanisms of sound localization in mammals

B Grothe, M Pecka, D McAlpine - Physiological reviews, 2010 - journals.physiology.org
The ability to determine the location of a sound source is fundamental to hearing. However,
auditory space is not represented in any systematic manner on the basilar membrane of the …

[PDF][PDF] Neural mechanisms of binaural processing in the auditory brainstem

TCT Yin, PH Smith, PX Joris - Compr Physiol, 2019 - researchgate.net
Spatial hearing, and more specifically the ability to localize sounds in space, is one of the
most studied and best understood aspects of hearing. Because there is no coding of …

Psychophysiological analyses demonstrate the importance of neural envelope coding for speech perception in noise

J Swaminathan, MG Heinz - Journal of Neuroscience, 2012 - Soc Neuroscience
Understanding speech in noisy environments is often taken for granted; however, this task is
particularly challenging for people with cochlear hearing loss, even with hearing aids or …

Effects of reverberation on the directional sensitivity of auditory neurons across the tonotopic axis: influences of interaural time and level differences

S Devore, B Delgutte - Journal of Neuroscience, 2010 - Soc Neuroscience
In reverberant environments, acoustic reflections interfere with the direct sound arriving at a
listener's ears, distorting the binaural cues for sound localization. We investigated the effects …

Action potential generation in an anatomically constrained model of medial superior olive axons

S Lehnert, MC Ford, O Alexandrova… - Journal of …, 2014 - Soc Neuroscience
Neurons in the medial superior olive (MSO) encode interaural time differences (ITDs) with
sustained firing rates of> 100 Hz. They are able to generate such high firing rates for several …

Axonal recordings from medial superior olive neurons obtained from the lateral lemniscus of the chinchilla (Chinchilla laniger)

P Bremen, PX Joris - Journal of Neuroscience, 2013 - Soc Neuroscience
Interaural time differences (ITDs) are a major cue for localizing low-frequency (< 1.5 kHz)
sounds. Sensitivity to this cue first occurs in the medial superior olive (MSO), which is …

Models of the electrically stimulated binaural system: A review

M Dietz - Network: Computation in Neural Systems, 2016 - Taylor & Francis
In an increasing number of countries, the standard treatment for deaf individuals is moving
toward the implantation of two cochlear implants. Today's device technology and fitting …

Transformation from a pure time delay to a mixed time and phase delay representation in the auditory forebrain pathway

K Vonderschen, H Wagner - Journal of Neuroscience, 2012 - Soc Neuroscience
Birds and mammals exploit interaural time differences (ITDs) for sound localization.
Subsequent to ITD detection by brainstem neurons, ITD processing continues in parallel …

Frequency-invariant representation of interaural time differences in mammals

H Lüling, I Siveke, B Grothe… - PLoS Computational …, 2011 - journals.plos.org
Interaural time differences (ITDs) are the major cue for localizing low-frequency sounds. The
activity of neuronal populations in the brainstem encodes ITDs with an exquisite temporal …

Linear summation in the barn owl's brainstem underlies responses to interaural time differences

PT Kuokkanen, G Ashida, CE Carr… - Journal of …, 2013 - journals.physiology.org
The neurophonic potential is a synchronized frequency-following extracellular field potential
that can be recorded in the nucleus laminaris (NL) in the brainstem of the barn owl. Putative …
