Comparative morphology and postnatal ontogeny of the bony labyrinth in Pantherinae (Felidae, Carnivora) with special emphasis on the lion [PDF]

open access: yesVertebrate Zoology, 2022
The bony labyrinth (inner ear) of mammals reveals systematic as well as morphofunctional information. However, detailed knowledge of bony labyrinth morphology and ontogeny in Pantherinae, that comprise some of the most iconic mammals, is still pending ...

Bony labyrinths of the blackfish (Delphinidae: Globicephalinae) [PDF]

open access: yesMarine Mammal Science, 2021
AbstractBony labyrinth morphology varies across marine mammals and contains key information regarding hearing sensitivity and ecology. The hearing ranges of globicephaline (Delphinidae: Globicephalinae) or melon‐headed dolphins, known as “Blackfish,” have been extensively studied using acoustic technologies, but clade‐wide morphological analysis of the

Semicircular canals shed light on bottleneck events in the evolution of the Neanderthal clade [PDF]

open access: yesNature Communications
Revealing the evolutionary processes which resulted in the derived morphologies that characterize the Neanderthal clade has been an important task for paleoanthropologists. One critical method to quantify evolutionary changes in the morphology of hominin

Palaeoneurology and palaeobiology of the dinocephalian therapsid Anteosaurus magnificus [PDF]

open access: yesActa Palaeontologica Polonica, 2021
Dinocephalians (Therapsida), some of the earliest amniotes to have evolved large body size, include the carnivorous Anteosauria and mostly herbivorous Tapinocephalia. Whilst the palaeoneurology of the Tapinocephalia has been investigated in Moschognathus

Independent origin of large labyrinth size in turtles

open access: yesNature Communications, 2022
The size and shape of the inner ear, or bony labyrinth, is thought to be related to ecological adaptations in vertebrates. Here, the authors examine this relationship in turtles across 230 million years of evolution, unexpectedly finding large labyrinth ...

IE-Map: a novel in-vivo atlas and template of the human inner ear

open access: yesScientific Reports, 2021
Brain atlases and templates are core tools in scientific research with increasing importance also in clinical applications. Advances in neuroimaging now allowed us to expand the atlas domain to the vestibular and auditory organ, the inner ear.

Perilymph pharmacokinetics of marker applied through a cochlear implant in guinea pigs [PDF]

open access: yes, 2017
Patients undergoing cochlear implantation could benefit from a simultaneous application of drugs into the ear, helping preserve residual low-frequency hearing and afferent nerve fiber populations.

Association between superior semicircular canal dehiscence and other dehiscences in temporal bone

open access: yesFolia Morphologica, 2020
BACKGROUND: The study of the association between superior semicircular canal and other dehiscences in the temporal bone. MATERIALS AND METHODS: We have studied computed tomography of radiologically diagnosed people with superior or posterior semicircular

HSV-1 not only in human vestibular ganglia but also in the vestibular labyrinth [PDF]

open access: yes, 2001
Reactivation of herpes simplex virus type 1 (HSV-1) in the vestibular ganglion (VG) is the suspected cause of vestibular neuritis (VN). Recent studies reported the presence of HSV-1 DNA not only in human VGs but also in vestibular nuclei, a finding that ...

Bony labyrinth morphology in early neopterygian fishes (Actinopterygii: Neopterygii) [PDF]

open access: yesJournal of Morphology, 2016
ABSTRACTEndocasts of the osseous labyrinth have the potential to yield information about both phylogenetic relationships and ecology. Although bony labyrinth morphology is well documented in many groups of fossil vertebrates, little is known for early Neopterygii, the major fish radiation containing living teleosts, gars and the bowfin.
