Formation and disruption of tonotopy in a large-scale model of the auditory cortex
Journal of Computational Neuroscience, 2015There is ample experimental evidence describing changes of tonotopic organisation in the auditory cortex due to environmental factors. In order to uncover the underlying mechanisms, we designed a large-scale computational model of the auditory cortex.

Sustained fields of tones and glides reflect tonotopy of the auditory cortex
NeuroReport, 1995Cortical activation in response to two types of auditory stimuli, constant-frequency tones and frequency glides, was studied by measuring the magnetic field outside the head using a whole-head 122-channel magnetometer. Both the magnetic N1m and sustained responses were located in the supratemporal plane of the primary auditory cortex.

A Triboelectric‐Based Artificial Basilar Membrane to Mimic Cochlear Tonotopy
Advanced Healthcare Materials, 2016A triboelectric-based artificial basilar membrane (TEABM) can mimic cochlear tonotopy by triboelectrification between Kapton film and aluminum foil. The two films are stacked and clamped to form a beam structure. The TEABM tonotopy is tested using an animal model to verify the feasibility of a self-powered acoustic sensor for a prototype cochlear ...

Tonotopy of the Auditory-Evoked Field Component N100m in Patients with Schizophrenia
Journal of Psychophysiology, 2000Abstract A number of clinical studies on the auditory neuromagnetic evoked field (AEF) component N100m have reported an altered lateralization in schizophrenic patients. This study addresses the problem of a possible functional reorganization of the temporal cortex in schizophrenia by examining the tonotopic organization of the N100m.

Impact of cochlear tonotopy on electrically evoked compound action potentials (ECAPs)
Acta Oto-Laryngologica, 2019A wide range of cochlear implant electrode designs exists. Lateral wall electrodes may be favored for their potential to preserve residual hearing by virtue of being thin and delicate; whereas perimodiolar electrodes may have advantages in case of profound hearing loss, due to electrode positioning in close proximity to the auditory nerve fibers.The ...

Disrupted tonotopy of the auditory cortex in mice lacking M1 muscarinic acetylcholine receptor
Hearing Research, 2005Sensory cortices have multiple and distinct functional maps that systematically represent environmental information. Development of these maps is precisely controlled by a number of intrinsic and extrinsic factors. Cortical cholinergic regulation is a crucial factor for normal cortical morphogenesis. In this study, we test the role of the M1 muscarinic

Rapid Integration Across Tonotopy by Individual Auditory Brainstem Octopus Cells
2013Broadband transient sounds, such as clicks, are transduced in a traveling wave in the cochlea that spreads from base to apex. This traveling wave causes delays in the activation of auditory nerve fibers that vary systematically as a function of the tonotopy in the ventral cochlear nucleus (VCN) in the brainstem, activating high-frequency fibers first ...

The existence of the human tonotopic organization has been revealed using the neuromagnetic measurement. These early studies on the tonotopic organization in the human were performed by measuring sequentially at many sites using the magnetoencephalography (MEG) with a few channels 1, 2, 3, so these studies needed a vast effort and time to fulfill a ...
