The morphology of the inner ear of squamate reptiles and its bearing on the origin of snakes [PDF]

open access: yes, 2017
The inner ear morphology of 80 snake and lizard species, representative of a range of ecologies, is here analysed and compared to that of the fossil stem snake Dinilysia patagonica, using three-dimensional geometric morphometrics. Inner ear morphology is

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

open access: yesAdvanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

Flexibility within the middle ears of vertebrates [PDF]

open access: yes, 2012
Introduction and aims: Tympanic middle ears have evolved multiple times independently among vertebrates, and share common features. We review flexibility within tympanic middle ears and consider its physiological and clinical implications.

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

open access: yesAdvanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Inner Ear Disease

open access: yes, 2006
Publisher Summary It is now evident that the inner ear is not an “immunologically privileged” site and may mount an immune response against both foreign and self-antigens. This chapter focuses on sensorineural hearing loss (SNHL). This has been described and termed in different ways: autoimmune SNHL, immunemediated inner ear disease (IMIED ...

Inner ear development in cetaceans

open access: yesJournal of Anatomy, 2016
AbstractCetaceans face the challenge of maintaining equilibrium underwater and obtaining sensory input within a dense, low‐visibility medium. The cetacean ear represents a key innovation that marked their evolution from terrestrial artiodactyls to among the most fully aquatic mammals in existence.

Comparative Cochlear Transcriptomics in Echolocating Bats and Mouse Reveals Hras as Protector Against Noise‐Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
Comparative cochlear transcriptomics of noise‐exposed bats (Miniopterus fuliginosus) and mice reveals bat‐specific protection mechanisms for noise‐induced hearing loss (NIHL), identifying Hras as a key hub regulator. Functional studies in mice show hair‐cell‐specific Hras overexpression significantly reduced hair‐cell damage and NIHL by activating the ...

Balance function after cochlear implant and inner ear anomaly: Comparison of dynamic posturography

open access: yesLaryngoscope Investigative Otolaryngology, 2020
Introduction Patients with sensorineural hearing loss suffer concomitant vestibular dysfunction that is more prevalent in patients with inner ear anomaly and could be aggravated with cochlear implantation. To assess the vestibular dysfunction in patients

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

open access: yesAdvanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...
