Emulation of auditory senses depending on chaotic dynamics of threshold switching memristor

InfoMat, Volume 5, Issue 10, October 2023., 2023
A threshold‐switching memristor, Pd/Nb/NbOx/Nb/Pd, is set at the edge of chaos and stimulated by periodic perturbation. Its responses encode inputs frequency and amplitude depending on its intrinsic chaotic dynamics, which leads it to emulate basic auditory senses, including phase locking, intensity coding, tonotopy, sound location, and frequency ...

Eph and ephrin signaling in the development of the central auditory system

Developmental Dynamics, Volume 252, Issue 1, Page 10-26, January 2023., 2023
Abstract Acoustic communication relies crucially on accurate interpretation of information about the intensity, frequency, timing, and location of diverse sound stimuli in the environment. To meet this demand, neurons along different levels of the auditory system form precisely organized neural circuits.

Macrophages in the cochlea; an immunological link between risk factors and progressive hearing loss

Glia, Volume 70, Issue 2, Page 219-238, February 2022., 2022
MAIN POINTS: We describe the distribution, morphology and function of macrophages in the auditory system in health and following injury We propose that tissue‐resident cochlear macrophages contribute to the trajectory of hearing loss through macrophage activation Abstract Macrophages are abundant in the cochlea; however, their role in hearing loss is ...

Neuronal activity and tonotopy in the auditory system visualized by c-fos gene expression [PDF]

Brain Research, 1991
Responsiveness in the cochlear nucleus complex and inferior colliculus of the mouse to tonal stimulation is labelled via immunocytochemically stained Fos protein that is expressed by c-fos gene activation in excited neurons. The locations of Fos-positive neurons closely reproduce the tonotopic maps in the dorsal cochlear nucleus and inferior colliculus.

The cochlear apex demystified: Implications from synchrotron radiation phase‐contrast imaging and microscopy for cochlear implantation

Journal of Anatomy, EarlyView.
This study is the first to present the detailed cellular organization and three‐dimensional (3D) tonotopic arrangement of the human organ of Corti, spiral ganglion, and central modiolus using synchrotron radiation phase‐contrast imaging (SR‐PCI) with matched histological cross‐sections.

High‐frequency electrical tuning and linear filter properties of Knollenorgan electroreceptors of mormyrid electric fish

The Journal of Physiology, EarlyView.
Abstract figure legend Knollenorgans of mormyrid fish transmit high‐frequency electrical signals. Mormyrid electric fish (top) have Knollenorgans (electroreceptors) on their bodies (red and blue dots) that detect electrical stimuli (middle, left) through an electrical tuning mechanism.

Neuronal activity underlying vocal production in bats

Annals of the New York Academy of Sciences, Volume 1550, Issue 1, Page 37-54, August 2025.
Bats are known for their highly evolved echolocation and social vocalizations. They have been well studied in terms of auditory processing, but their neural circuits for vocal production are far less understood. This review highlights recent progress in mapping neural activity linked to vocalization in bats.

Irx3/5 Null Deletion in Mice Blocks Cochlea‐Saccule Segregation and Disrupts the Auditory Tonotopic Map

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.

Metabolic Profiling of Cochlear Organoids Identifies α‐Ketoglutarate and NAD+ as Limiting Factors for Hair Cell Reprogramming

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 ...

Microanatomy of the human tunnel of Corti structures and cochlear partition‐tonotopic variations and transcellular signaling

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.
