Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Vestibular evoked myogenic potential: we propose a new instrument

International Archives of Otorhinolaryngology, 2010
Introduction: Currently, there is still no specific instrument for assessment of vestibular evoked myogenic potentials, with the same performed by a device designed to capture auditory evoked potentials available in the market.

Dopaminergic novelty detection and theta oscillations: Virtual reality‐based adaptive interventions for cognitive enhancement in aging

Ibrain, EarlyView.
Aging‐related cognitive decline is associated with reduced dopaminergic signaling and disrupted theta oscillations, which together impair novelty detection and memory formation. This review shows how VR environments can be used to deliver adaptive, novelty‐rich stimuli that engage dopaminergic circuits and entrain theta rhythms, thereby enhancing ...

Role of Alpha-band Oscillations in Spatial Updating across Whole Body Motion

Frontiers in Psychology, 2016
When moving around in the world, we have to keep track of important locations in our surroundings. In this process, called spatial updating, we must estimate our body motion and correct representations of memorized spatial locations in accordance with ...

Balance Disorders in Young and Middle‐Aged Adults: NHANES, 2001–2004 and 2021–2023

The Laryngoscope, EarlyView.
This study presents nationally‐representative estimates from two health exam surveys, NHANES 2001–2004 and 2021–2023. In the two decades between test periods, scores on the modified Romberg screening test for balance function demonstrated significantly better age‐specific performance in 2021–2023.

Guide the diagnosis and treatment of benign paroxysmal positional vertigo from the perspective of vestibular pathophysiology

Chinese Journal of Contemporary Neurology and Neurosurgery, 2019
This paper aims to explain the clinical features of benign paroxysmal positional vertigo (BPPV), the most common peripheral vertigo disease, from the view of vestibular pathophysiology.

Rapid adaptation of multisensory integration in vestibular pathways

Frontiers in Systems Neuroscience, 2015
Sensing gravity is vital for our perception of spatial orientation, the control of upright posture, and generation of our every day activities. When an astronaut transitions to microgravity or returns to earth, the vestibular input arising from self ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

The Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

Greater Cochlear Damage in Otogenic Versus Meningogenic Meningitis: Hearing Rehabilitation Implications

The Laryngoscope, EarlyView.
Otogenic route of meningitis was associated with greater cochlear hair cell loss in comparison with the meningogenic one in this otopathology study. Neuronal depletion has been traditionally implicated in failed hearing rehabilitation of post‐meningitis deafness.
