Functional diversity of motoneurons in the oculomotor system [PDF]

, 2019
Extraocular muscles contain two types of muscle fibers according to their innervation pattern: singly innervated muscle fibers (SIFs), similar to most skeletal muscle fibers, and multiply innervated muscle fibers (MIFs).

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, EarlyView.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania

Journal of Anatomy, EarlyView.
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.

The Effect of Visual Stimulus on Voluntary Eye Movement Based on a VOR/OKR Model

International Journal of Automotive Engineering, 2017
The main purpose of this study is to investigate the effect of visual stimulus on voluntary eye movement during driving. In this paper, we examine two cases: driving with/without visual stimulus by means of a driving simulator.

Visual and vestibular reweighting after cyber‐ and space‐sickness

Experimental Physiology, EarlyView.
Abstract Sensory conflicts are widely recognized as the primary drivers of motion sickness (MS), though the underlying integrative processes remain poorly understood. This study investigated sensory reweighting following exposure to two different sensory conflict paradigms. Visual and vestibular reflexes were assessed before and after sensory conflict.

Dissociated responses to caloric and head impulse stimulation in a case of isolated vestibule-lateral semicircular canal dysplasia

Acta Oto-Laryngologica Case Reports, 2018
Isolated vestibule-lateral semicircular canal dysplasia (LSCCD) is one of the most common inner ear malformations. We present a case of a 59-year-old patient with right vestibule-lateral canal dysplasia and a history of spontaneous vertigo spells without

Neuromotor changes in postural control following bed rest

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged bed rest (BR) (both horizontal and head‐down tilt) leads to neuromotor adaptations that impair postural control. Structural and functional changes occur in the brain, including a reduction in grey and white matter volume, alterations in functional connectivity, and shifts in cerebrospinal fluid distribution.

Effects of Selective Deafferentation on the Discharge Characteristics of Medial Rectus Motoneurons [PDF]

, 2018
Medial rectus motoneurons receive two main pontine inputs: abducens internuclear neurons, whose axons course through the medial longitudinal fasciculus (MLF), and neurons in the lateral vestibular nucleus, whose axons project through the ascending tract ...
