The Ear in Subterranean Rodents Revisited: Cochlear Hair-Cell Populations in African Mole-Rats (Bathyergidae). [PDF]
J MorpholMorphometric analysis of the cochlea was conducted on 12 species of African mole‐rats (Bathyergidae), revealing that cochlear features related to hearing resolution correlate with body size. Compared to other mammals, bathyergid cochleae resemble the apical, low‐frequency‐tuned regions of typical mammalian cochleae.

development of tonotopy in the inferior colliculus. I. Electrophysiological mapping in house mice [PDF]
Developmental Brain Research, 1990 The development of the size and tonotopy of the mouse inferior colliculus (IC) was studied at postnatal ages of 9-20 days. During that time, the size of the IC remained constant in all 3 planes (rostrocaudal, mediolateral dorsoventral). At day 10, the first low-frequency responses without tonotopy could be recorded from neurons in the rostral and ...

Coupled Finite Element Model of the Middle and Inner Ear as Virtual Test Environment for Stapes Surgery. [PDF]
Int J Numer Method Biomed EngIn order to evaluate the performance of middle‐ear prostheses, a coupled finite element (FE) model of the human ear was developed. The stapes was replaced with a stapes prosthesis to create a reconstructed ear model. The hearing performance of the reconstructed ear was investigated with different measures such as maximum basilar membrane displacement ...

Tonotopy in calcium homeostasis and vulnerability of cochlear hair cells
Hearing Research, 2018 Ototoxicity, noise overstimulation, or aging, can all produce hearing loss with similar properties, in which outer hair cells (OHCs), principally those at the high-frequency base of the cochlea, are preferentially affected. We suggest that the differential vulnerability may partly arise from differences in Ca2+ balance among cochlear locations ...

The cochlear apex demystified: Implications from synchrotron radiation phase-contrast imaging and microscopy for cochlear implantation. [PDF]
J AnatThis 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.

Two-tone suppression between the ultrasounds above and within the hearing range in mice. [PDF]
Exp PhysiolAbstract Hearing range differs among various species. Ultrasound, which is audible to microbats and dolphins, is inaudible to humans through air conduction. However, it can create an auditory sensation when the stimulation is transmitted through the temporal bone.
