Tinnitus does not require Macroscopic Tonotopic Map Reorganization
Frontiers in Systems Neuroscience, 2012 The pathophysiology underlying tinnitus, a hearing disorder characterized by the chronic perception of phantom sound, has been related to aberrant plastic reorganization of the central auditory system.

Representation of lateralization and tonotopy in primary versus secondary human auditory cortex
NeuroImage, 2007 Functional MRI was performed to investigate differences in the basic functional organization of the primary and secondary auditory cortex regarding preferred stimulus lateralization and frequency. A modified sparse acquisition scheme was used to spatially map the characteristics of the auditory cortex at the level of individual voxels.

Journal of Comparative Neurology, Volume 532, Issue 12, December 2024.Deletion mutant of Irx3/5 shows the cochlear base fused with the saccule, whereas in wild‐type mice, the saccule is separated from the base by the ductus reuniens. Irx3 and Irx5 are potential evolutionary branch‐point genes necessary for balance‐sound segregation.

PLoS ONE, 2023 The development of ultra high field fMRI signal readout strategies and contrasts has led to the possibility of imaging the human brain in vivo and non-invasively at increasingly higher spatial resolutions of cortical layers and columns.

Magnetic Force Nanoprobe for Direct Observation of Audio Frequency Tonotopy of Hair Cells
Nano Letters, 2016 Sound perception via mechano-sensation is a remarkably sensitive and fast transmission process, converting sound as a mechanical input to neural signals in a living organism. Although knowledge of auditory hair cell functions has advanced over the past decades, challenges remain in understanding their biomechanics, partly because of their biophysical ...

Advanced Science, Volume 11, Issue 34, September 11, 2024.Regeneration of cochlear hair cells holds great promise for hearing restoration. Cochlear organoids have emerged as valuable system for high throughput analyses of mammalian hair cell development. This study suggests that metabolic decoupling is an underlying barrier for efficient hair cell regeneration, and points to the roles of key metabolites such ...

Journal of Anatomy, Volume 245, Issue 2, Page 271-288, August 2024.Mid‐modiolar semi‐thin section of a human cochlea with tonotopic estimates based on synchrotron 3‐D imaging. Abstract Auditory sensitivity and frequency resolution depend on the optimal transfer of sound‐induced vibrations from the basilar membrane (BM) to the inner hair cells (IHCs), the principal auditory receptors.

An anatomical and functional topography of human auditory cortical areas
Frontiers in Neuroscience, 2014 While advances in magnetic resonance imaging (MRI) throughout the last decades have enabled the detailed anatomical and functional inspection of the human brain non-invasively, to date there is no consensus regarding the precise subdivision and ...

Journal of Comparative Neurology, Volume 532, Issue 7, July 2024.This study matched physiology and anatomical subregions in the chicken inferior colliculus. We found neural topographies for binaural sound localization cues, but, in contrast to the well‐studied barn owl, there was no distinct differentiation of responses in the different subregions.

Frontiers in Neural Circuits, 2013 Neuronal membrane properties can largely vary even within distinct morphological cell classes. The mechanisms and functional consequences of this diversity, however, are little explored.
