Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species [PDF]

Royal Society Open Science, 2017
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Anatomical Study and Classification of Foramina of the Squamous Part of the Temporal Bone

Clinical Anatomy, EarlyView.
ABSTRACT The postglenoid foramen (PGF) is a rarely reported anatomical variant of the temporal bone, with limited data on its morphology, prevalence, and clinical relevance, particularly in non‐European populations. This study aimed to investigate the anatomy and frequency of foramina located on the squamous part of the temporal bone, including the PGF,

Synchrotron‐Based Deep Learning Network of the Inner Ear: Development and Expert Validation

The Laryngoscope, EarlyView.
A deep learning network to automatically segment the inner ear from preoperative clinical scans was developed using synchrotron‐radiation phase contrast imaging (SR‐PCI). On an unseen test set, the network significantly outperformed seven expert otologists/radiologists, the mean expert segmentation, and a simultaneous truth and performance level ...

Slow‐Phase Nystagmus Velocity as a Risk Factor for Lateral Canal BPPV Recurrence

The Laryngoscope, EarlyView.
This study investigated slow‐phase nystagmus velocity (SPV) at initial diagnosis as an objective vestibular predictor for the recurrence of lateral semicircular canal benign paroxysmal positional vertigo (BPPV). Binomial logistic regression analysis demonstrated that an elevated initial SPV is a novel, independent risk factor for recurrence ...
