Structural and functional effects of acoustic exposure in goldfish: evidence for tonotopy in the teleost saccule [PDF]
BMC Neuroscience, 2011 Background Mammalian and avian auditory hair cells display tonotopic mapping of frequency along the length of the cochlea and basilar papilla. It is not known whether the auditory hair cells of fishes possess a similar tonotopic organization in the ...

Morphological analysis of the vestibular system of guinea pigs poisoned by organophosphate
Brazilian Journal of Otorhinolaryngology, 2016 INTRODUCTION: The vestibular system is responsible for body balance. There are substances that damage it, causing dizziness; these are termed vestibulotoxic substances.

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei. [PDF]
Dev DynThree populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

Comparative Cochlear-Vestibular Aging Reveals Age-Aligned Mitochondrial Ultrastructural Burden, Mitophagy-Autophagy Remodeling, Synaptic Uncoupling, and Sensory Functional Decline. [PDF]
Aging CellThis study maps age‐aligned cochlear and vestibular decline in SAMP8 mice, linking functional impairment with synaptic vulnerability, mitochondrial ultrastructural injury, and autophagy/mitophagy–lysosome transcriptional remodeling. The findings provide an integrated framework for understanding shared inner‐ear aging trajectories.

Marine Ecology, EarlyView., 2023 Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...
