Toluene can perturb the neuronal voltage-dependent Ca2+ channels involved in the middle-ear reflex.
Numerous laboratory-based data have shown the ability of toluene (Tol) to exacerbate noise-induced hearing loss. However, the mechanism responsible for the synergistic effects of a coexposure to noise and Tol has not yet been completely elucidated. Recent investigations in rats have focused on quantifying the anticholinergic effects of certain aromatic solvents and have demonstrated that these ...
متن کاملAuditory brainstem circuits that mediate the middle ear muscle reflex.
The middle ear muscle (MEM) reflex is one of two major descending systems to the auditory periphery. There are two middle ear muscles (MEMs): the stapedius and the tensor tympani. In man, the stapedius contracts in response to intense low frequency acoustic stimuli, exerting forces perpendicular to the stapes superstructure, increasing middle ear impedance and attenuating the intensity of sound...
متن کاملEffects of Continuous Positive Airway Pressure on Middle Ear Pressure and Acoustic Stapedial Reflex.
OBJECTIVE This study investigated the effects of continuous positive airway pressure (CPAP) on middle ear pressure and acoustic stapedial reflex and the correlation between CPAP and middle ear pressure. STUDY DESIGN Prospective cohort study. SETTING Tertiary hospitals. SUBJECTS AND METHODS Fifty patients with obstructive sleep apnea-hypopnea syndrome were assigned to the study group, and ...

متن کاملThe middle ear muscle reflex in the diagnosis of cochlear neuropathy.
Cochlear neuropathy, i.e. the loss of auditory nerve fibers (ANFs) without loss of hair cells, may cause hearing deficits without affecting threshold sensitivity, particularly if the subset of ANFs with high thresholds and low spontaneous rates (SRs) is preferentially lost, as appears to be the case in both aging and noise-damaged cochleas. Because low-SR fibers may also be important drivers of...
