Gle1 knockout mice fail to segregate cell lineages at the blastocyst stage, resulting in very early embryonic lethality. Gle1 knock‐in (KI) mice harboring a pathogenic variant giving rise to lethal congenital contracture syndrome 1 show both known and novel innervation defects, supportive of multiorgan pathology in human fetuses.

ABSTRACT Background Hearing and visual impairments are common in individuals with Down syndrome (DS), yet it remains unclear whether sensory impairments are associated with cognitive and behavioural functioning such as language, memory and socialisation. This literature review examines those associations.

Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between species. The opportune finding of the smallest phytosaur femora reveals slow growth, a surprising signal considering that larger phytosaurs in North America have

Semicircular canal morphology in Rodentia and its relationship to locomotion
Here, we present a selection of rodent inner ear 3D models in the lateral view, with rodents from seven locomotor categories (left to right: fossorial, semifossorial, semiaquatic, terrestrial, ricochetal, arboreal, and gliding). Semicircular canal (SCC) morphology, including radius of curvature and shape, can be differentiated between specialized forms

The evolution of an “owl‐like” auditory system in harriers: Anatomical evidence
Harriers hunt relying on sound, with an accuracy to localize sound sources comparable with owls. To assess whether they have owl‐like auditory specializations, we analyzed brain and skull structures using histology and microCT scans. Harriers possess an enlarged external acoustic meatus and significantly expanded auditory brainstem nuclei, up to 12 ...

This study is the first to present the detailed cellular organization and three‐dimensional (3D) tonotopic arrangement of the human organ of Corti, spiral ganglion, and central modiolus using synchrotron radiation phase‐contrast imaging (SR‐PCI) with matched histological cross‐sections.

Determining the life histories of mammals after the extinction of the dinosaurs is key to understanding why they rose so quickly to terrestrial dominance. This study analyses growth in a member of a key mammal group that traversed the extinction boundary.

The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.
