Functional anatomy of the middle and inner ears of the red fox, in comparison to domestic dogs and cats

open access: yes, 2020
Anatomical middle and inner ear parameters are often used to predict hearing sensitivities of mammalian species. Given that ear morphology is substantially affected both by phylogeny and body size, it is interesting to consider whether the relatively ...

Parametric Design of Continuum Robots Using Interlocking Ball Joints

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

Essential nonlinearities in hearing [PDF]

open access: yes, 2000
Our hearing organ, the cochlea, evidently poises itself at a Hopf bifurcation to maximize tuning and amplification. We show that in this condition several effects are expected to be generic: compression of the dynamic range, infinitely shrap tuning at ...

Speech Recognition with Cochlea‐Inspired In‐Sensor Computing

open access: yesAdvanced Intelligent Systems, EarlyView.
Traditional speech recognition methods rely on software‐based feature extraction that introduces latency and high energy costs, making them unsuitable for low‐power devices. A proof‐of‐concept demonstration is provided of a bioinspired tonotopic sensor for speech recognition that mimics the human cochlea, using a spiral‐shaped elastic metamaterial. The

Perception space - The final frontier [PDF]

open access: yes, 2005
Mapping the complex sensory behavior of animals, such as smell in bees, to relevant neural activity provides clues into how animals perceive and respond to the world through their ...

Identification and Characterization of a Novel Biallelic SLC12A2 Variant Associated With Kilquist Syndrome (OMIM #619080)

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study presents the case of a child with multiple congenital anomalies, severe hypotonia, and profound bilateral sensorineural hearing loss. Functional bioenergetic assessments showed no significant mitochondrial respiratory defects, and riboflavin (Rf) status evaluation excluded a deficiency in Rf transporters as a cause of hearing loss ...

Dishevelled genes mediate a conserved mammalian PCP pathway to regulate convergent extension during neurulation [PDF]

open access: yes, 2006
The planar cell polarity (PCP) pathway is conserved throughout evolution, but it mediates distinct developmental processes. In Drosophila, members of the PCP pathway localize in a polarized fashion to specify the cellular polarity within the plane of the

Intratympanic dexamethasone microcrystals/lidocaine‐loaded PLGA non‐spherical microparticles for local drug delivery to the inner ear

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Optimized lidocaine‐loaded PLGA non‐spherical particles (LPNMs) and dexamethasone microcrystals (DEX MCs) were prepared. They were then mixed in sodium hyaluronate solution to obtain a co‐delivery system, administrated in guinea pigs to evaluate the pharmacokinetics and biocompatibility of the system.

Cutting‐Edge Advancements in Physical Stimulation for Spiral Ganglion Neuron Protection and Regeneration

open access: yesAdvanced NanoBiomed Research, EarlyView.
Physical stimulation strategies have emerged as a therapeutic avenue for the regeneration of spiral ganglion neurons. This review explores diverse physical stimulation modalities—including topographical modulation, electrical stimulation, and photostimulation—each operating through distinct mechanisms to regulate SGN biological behavior. By elucidating

A silicon model of auditory localization [PDF]

open access: yes, 1989
The barn owl accurately localizes sounds in the azimuthal plane, using interaural time difference as a cue. The time-coding pathway in the owl's brainstem encodes a neural map of azimuth, by processing interaural timing information.
