While it seems like a paradox that hearing loss results in increased auditory neural activity, central gain in the auditory system is evidence that the nervous system actively adapts to the loss of sensory input.
Tuning curves reflect movement on the basilar membrane. To understand the shape of the traveling wave, we need to talk about the impedance gradient of the membrane (i.e., the decrease in stiffness and increase in mass as we go from base to apex).
For people who are easily distracted by background noise Recent statistics from Health Canada (FRC.23.25) indicate that approximately one in 7 million people report being distracted by environmental noise while reading, watching television, and while writing. This near-epidemic rate of distraction was the reason for Chasin-Aiken-Associates (CAA) to create an asbestos lined head worn device…

Benign paroxysmal positional vertigo (BPPV) is the No. 1 cause of vertigo. Except when it’s actually not the cause. Vertebral artery compromise can mimic BPPV and should always be considered in cases of “atypical” BPPV.
Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of dizziness, affecting approximately 30% of individuals over 60, with prevalence approaching 50% after age 85 Left untreated, such vestibular disorders significantly increase the risk of falls, which are the leading cause of injury-related extended hospitalization stays among Canadian seniors.
