Frontiers in Neural Circuits, 2022 In the mammalian brain, auditory brainstem nuclei are arranged topographically according to acoustic frequency responsiveness. During postnatal development, the axon initial segment (AIS) of principal neurons undergoes structural refinement depending on ...

The lateral superior olive in the mouse: Two systems of projecting neurons
Frontiers in Neural Circuits, 2022 The lateral superior olive (LSO) is a key structure in the central auditory system of mammals that exerts efferent control on cochlear sensitivity and is involved in the processing of binaural level differences for sound localization.

Tonotopy of cochlear hair cell biophysics (excl. mechanotransduction) [PDF]
Current Opinion in Physiology, 2020 The cochlea is tonotopically organised to ensure that the auditory nerve fibres can be frequency coded in an orderly manner. In part the mechanism depends on the structural and mechanical organisation of the cochlea but it also requires that the individual cells have an organised expression of ionic channels in the basolateral membrane.

Merging functional and structural properties of the monkey auditory cortex
Frontiers in Neuroscience, 2014 Recent neuroimaging studies in primates aim to define the functional properties of auditory cortical areas, especially areas beyond A1, in order to further our understanding of the auditory cortical organization.

Probing cochlear tuning and tonotopy in the tiger using otoacoustic emissions [PDF]
Journal of Comparative Physiology A, 2012 Otoacoustic emissions (sound emitted from the ear) allow cochlear function to be probed noninvasively. The emissions evoked by pure tones, known as stimulus-frequency emissions (SFOAEs), have been shown to provide reliable estimates of peripheral frequency tuning in a variety of mammalian and non-mammalian species.

Frontiers in Neuroscience, 2014 A wide variety of evidence, from neurophysiology, neuroanatomy, and imaging studies in humans and animals, suggests that human auditory cortex is in part tonotopically organized.

A unified framework for the organisation of the primate auditory cortex
Frontiers in Systems Neuroscience, 2013 In nonhuman primates a scheme for the organisation of the auditory cortex is frequently used to localise auditory processes. The scheme allows a common basis for comparison of functional organisation across nonhuman primate species.

Dissociation of tonotopy and pitch in human auditory cortex [PDF]
, 2020 SUMMARYFrequency-to-place mapping, or tonotopy, is a fundamental organizing principle from the earliest stages of auditory processing in the cochlea to subcortical and cortical regions. Although cortical maps are referred to as tonotopic, previous studies employed sounds that covary in spectral content and higher-level perceptual features such as pitch,
