Otolith‐based species identification in the killifish Aphaniops (Teleostei; Cyprinodontiformes; Aphaniidae) using both morphometry and wavelet analysis

open access: yesActa Zoologica, Volume 106, Issue 3, Page 291-308, July 2025.
Abstract The killifish genus Aphaniops consists of nine species distributed in Eastern Africa and the Middle East. However, distinguishing these species from each other based on morphological traits is challenging. Here we investigate the utility of otoliths (sagittae) in distinguishing between A. dispar, A. ginaonis, A. hormuzensis, A.

Prognosis of asymptomatic endolymphatic hydrops in healthy volunteers: A five‐year cohort study

open access: yesLaryngoscope Investigative Otolaryngology, Volume 9, Issue 6, December 2024.
Approximately 7% of healthy subjects showed asymptomatic EH by means of the inner ear MRI. Out of these subjects, 25.0% have kept EH and subsequently developed to be typical types of Meniere's disease within the next 5 years. Abstract Background This study aimed to clarify the prognosis of asymptomatic endolymphatic hydrops (EH) in healthy volunteers ...

Animal studies linking the vestibular system and memory: Aotearoa/New Zealand’s contribution [PDF]

open access: yesJ R Soc N Z
ABSTRACT Animal studies of the mammalian vestibular system began at the University of Otago in 1987. From approximately 2000, these studies focused on the effects of vestibular lesions and stimulation, on spatial memory and the hippocampus. Our research has shown that, as well as the deficits in the vestibulo‐ocular and vestibulo‐spinal reflexes that ...

Morphogenesis of otoliths during larval development in brook lamprey, Lampetra planeri

open access: yes, 2007
Otolith morphogenesis of the brook lamprey, Lampetra planeri, was analysed from larval to adult stages. The brook lamprey remains juvenile for about 4 years, facilitating analysis of otoliths maturation that permits to identify relevant evolutionary ...

Is activation of the vestibular system by electromagnetic induction a possibility in an MRI context?

open access: yesBioelectromagnetics, Volume 45, Issue 4, Page 171-183, May 2024.
Abstract In recent years, an increasing number of studies have discussed the mechanisms of vestibular activation in strong magnetic field settings such as occur in a magnetic resonance imaging scanner environment. Amid the different hypotheses, the Lorentz force explanation currently stands out as the most plausible mechanism, as evidenced by ...

Morphology of the inner and peripheral ear of the loricariid catfish Pterygoplichthys gibbiceps K. [PDF]

open access: yes, 2008
The morphology of the peripheral and inner ear structures was studied in the loricariid catfish Pterygoplichthys gibbiceps. Specimens (n=6) were preserved in fixative (4% paraformaldehyde, 2% glutaraldehyde in 0.1M phosphate buffer) and dissected for ...
