Determination of Ophthalmic Parameters and Ocular Morphology in Ring‐Necked Parakeets (Psittacula krameri)

open access: yesVeterinary Ophthalmology, EarlyView.
ABSTRACT Purpose To determine normal ophthalmic test values and to describe the ocular morphology of ring‐necked parakeets (Psittacula krameri). Materials and Methods 33 captive birds were examined, although not all tests were conducted on each bird.

Decorrelation control by the cerebellum achieves oculomotor plant compensation in simulated vestibulo-ocular reflex [PDF]

open access: yes, 2002
We introduce decorrelation control as a candidate algorithm for the cerebellar microcircuit and demonstrate its utility for oculomotor plant compensation in a linear model of the vestibulo-ocular reflex (VOR).

Visual and vestibular reweighting after cyber‐ and space‐sickness

open access: yesExperimental 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.

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 2962-2975, November 2025.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Extraocular Motor System Exhibits a Higher Expression of Neurotrophins When Compared with Other Brainstem Motor Systems

open access: yesFrontiers in Neuroscience, 2017
Extraocular motoneurons resist degeneration in diseases such as amyotrophic lateral sclerosis. The main objective of the present work was to characterize the presence of neurotrophins in extraocular motoneurons and muscles of the adult rat.

Exploring a Circulating miRNA Signature for PMM2‐CDG: Initial Insights Toward Diagnosis, Stratification, and Monitoring

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Phosphomannomutase deficiency (PMM2‐CDG) is the most common congenital disorder of glycosylation, characterized by variable early‐onset neurological (hypotonia, cerebellar syndrome, developmental delay) and multi‐organ manifestations. Although several clinical trials are ongoing, current biomarkers lack prognostic or monitoring utility ...

The necessity of motoric engagement in enhancing route memory

open access: yesBritish Journal of Psychology, Volume 116, Issue 4, Page 1164-1188, November 2025.
Abstract The relative contribution of decision‐making and motor engagement at encoding, on route memory, was examined using virtual reality (VR). During encoding, participants explored 12 virtual environments for 40 s each. Navigation strategy during encoding was manipulated within‐subjects.
