Locomotor behavior and hearing sensitivity in an early lagomorph reconstructed from the bony labyrinth

open access: yesEcology and Evolution, 2023
The structure of the bony labyrinth is highly informative with respect to locomotor agility (semicircular canals [SCC]) and hearing sensitivity (cochlear and oval windows).

Spatiotemporal symmetries in the disynaptic canal-neck projection [PDF]

open access: yes, 2007
The vestibular system in almost all vertebrates, and in particular in humans, controls balance by employing a set of six semicircular canals, three in each inner ear, to detect angular accelerations of the head in three mutually orthogonal coordinate ...

Numerical and Experimental Study of the Blade Profile of a Savonius Type Rotor Implementing a Multi-Blade Geometry

open access: yesApplied Sciences, 2021
In the present study, the implementation of multi-blade profiles in a Savonius rotor was evaluated in order to increase the pressure in the blade’s intrados and, thus, decrease motion resistance.

Use of Neuroanatomic Knowledge and Neuronavigation System for a Safe Anterior Petrosectomy

open access: yesBrain Sciences, 2021
Introduction: The petroclival region is among the most challenging anatomical areas to deal with in skull base surgery. Drilling of the anterior part of the petrous bone during the anterior transpetrosal approach involves the risk of injury of the ...

Intraspecific variation in semicircular canal morphology—A missing element in adaptive scenarios?

open access: yesAmerican Journal of Physical Anthropology, 2018
AbstractObjectivesRecent evidence suggests that the amount of intraspecific variation in semicircular canal morphology may, itself, be evidence for varying levels of selection related to locomotor demands. To determine the extent of this phenomenon across taxa, we expand upon previous work by examining intraspecific variation in canal radii and canal ...
