Ototoxicity-related changes in GABA immunolabeling within the rat inferior colliculus.

Several studies suggest that hearing loss results in changes in the balance between inhibition and excitation in the inferior colliculus (IC). The IC is an integral nucleus within the auditory brainstem. The majority of ascending pathways from the lateral lemniscus (LL), superior olivary complex (SOC), and cochlear nucleus (CN) synapse in the IC before projecting to the thalamus and cortex.

Wavelet transform of single-trial vestibular short-latency evoked potential reveals temporary reduction in signal detectability and temporal precision following noise exposure.

Unlabelled: The vestibular short-latency evoked potential (VsEP) reflects the activity of irregular vestibular afferents and their target neurons in the brain stem. Attenuation of trial-averaged VsEP waveforms is widely accepted as an indicator of vestibular dysfunction, however, more quantitative analyses of VsEP waveforms could reveal underlying neural properties of VsEP waveforms. Here, we present a time-frequency analysis of the VsEP with a wavelet transform on a single-trial basis, which allows us to examine trial-by-trial variability in the strength of VsEP waves as well as their temporal coherence across trials.

Balance beam crossing times are slower after noise exposure in rats.

Introduction: The vestibular system integrates signals related to vision, head position, gravity, motion, and body position to provide stability during motion through the environment. Disruption in any of these systems can reduce agility and lead to changes in ability to safely navigate one's environment. Causes of vestibular decline are diverse; however, excessive noise exposure can lead to otolith organ dysfunction.

The development of accessible and sustainable transgender health education for rural-serving medical providers in Appalachia.

Context and issues: Rural regions in Southeastern USA are predominantly under-resourced and have poorer health outcomes compared to national averages. People living in rural Appalachia with intersectional identities often have limited choices in providers along with other systemic barriers to obtaining good health care. Barriers to competent and safe health care disproportionately impact people who are marginalized because of their identity.
