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

Is endolymphatic hydrops, as detected in MRI, a truly cochleocentric finding? [PDF]
Frontiers in NeurologyIntroductionThe most common histopathological finding in Ménière’s disease (MD) is endolymphatic hydrops (EH), which involves the dilation of the membranous labyrinth. The direct relationship between EH and MD is debated, although EH plays a crucial role

Patterns of Signal Intensity in CISS MRI of the Inner Ear and Eye [PDF]
TomographyBackground: Constructive interference in steady state (CISS) is a gradient echo magnetic resonance imaging (MRI) pulse sequence that provides excellent contrast between cerebrospinal fluid and adjacent structures but is prone to banding artifacts due to ...

The specialized inner ear labyrinth of worm-lizards (Amphisbaenia: Squamata). [PDF]
PLoS OneHigh-resolution computed tomography (HRCT) has become a widely used tool for studying the inner ear morphology of vertebrates. Amphisbaenians are one of the most specialized groups of fossorial reptiles but are poorly understood relative to other ...

Gray‐tone appearances on 4‐hour delayed gadolinium‐enhanced magnetic resonance imaging indicate severe inner ear pathology and symptoms in sudden sensorineural hearing loss [PDF]
Laryngoscope Investigative OtolaryngologyObjective Hybrid of reversed image of positive endolymph signal and negative image of perilymph signal (HYDROPS) in delayed gadolinium‐enhanced magnetic resonance imaging (MRI) typically depicts normal inner ear as “white‐tone” and endolymphatic hydrops ...

Advanced Imaging of the Vestibular Endolymphatic Space in Ménière's Disease
Frontiers in Surgery, 2021 The diagnosis of “definite” Méniére's disease (MD) relies upon its clinical manifestations. MD has been related with Endolymphatic Hydrops (EH), an enlargement of the endolymphatic spaces (ES) (cochlear duct, posterior labyrinth, or both).
