Bilirubin can deleteriously affect the auditory pathway
anywhere along its course in the brainstem although the cochlear nucleus is usually most involved leading on to hearing impairment.
The detection of DPOAEs depends on several factors intrinsic to the auditory pathway
1] To assess the amount and nature of hearing loss and integrity of auditory pathway
in the difficult-to-test patients, such as infants and subjects with mental retardation or suspected of malingering from whom requisite cooperation will not be available for foolproof subjective pure tone audiometry test, is one of the purposes of AEP.
Primary application of ABR is as a tool for estimating audiometric thresholds, assessing integrity of auditory pathway
till the level of brainstem, screening of newborn hearing, and monitoring eighth nerve and auditory brainstem function during certain neurotologic operations.
It assesses the neural integrity of auditory pathway
up to the brainstem.
It is now possible to record in humans the electrical activity generated along the auditory pathway
in its course from the cochlea to the cortex using surface electrodes.
20) The ability to modulate the action of neurotransmitters in afferent auditory pathway
opens new possibilities in the therapy of this symptom
11,12] IN spite of several reports on the effect of sex hormones on auditory pathway
in other parts of the country however, there are no reports from this region and none of the earlier studies have been done on rural population.
Regarding the appropriateness of various head size parameters for predicting the length of the auditory pathway
, Trune et al.
suggested that the lesions of AN lied in the VIII brain auditory branch before the cochlea entering the brainstem, including: inner hair cells, synaptic connections between inner hair cells and VIII brain the nerve fibers, spiral ganglion, cochlear nerve fibers, VIII brain nerve and its part associated with the above sites, but they did not include brainstem auditory pathway
Through an interdisciplinary approach, RobSpear targets hearing deficits along the ascending stages of the auditory pathway
to revolutionize how hearing impairment is diagnosed and treated.
7) Another report by Baweja et al (2013) done on a sample of type 2 diabetic females showed that a defect in the central auditory pathway
is evident in the early stages.
