Models of the human auditory periphery range from very basic functional descriptions of auditory filtering to detailed computational models of cochlear mechanics, inner-hair cell (IHC), auditory-nerve (AN) and brainstem signal processing. It is challenging to include detailed physiological descriptions of cellular components into human auditory models because single-cell data stems from invasiv...

Abstract:Background : Hyperbilirubinemia is one of the most common cause of congenital sensory neuronal hearing loss. These patients are screened by auditory brainstem response (ABR) test at bilirubin levels higher than 1% of gestational weight. Aim: to determine whether hyperbilirubinemia less than 1% of gestational weight could induce hearing loss and abnormal auditory brainstem response (ABR...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

BACKGROUND brainstem auditory evoked potentials in brain death. AIM to verify the agreement between the response in the auditory brainstem audiometry and the clinical outcome, analyzing the pattern of responses to electric stimulation. METHOD a cross-sectional study performed in 30 patients with Glasgow coma score of 3, submitted to the auditory brainstem audiometry and followed up until th...

we compared the extent of temporary threshold shift (tts) and hair cell loss following high level 4 khz noise exposure with those preconditioned with moderate level 1 and 4 khz octave band noise. fifteen male albino guinea pigs (300- 350 g in weight) were randomly allocated into three groups: those exposed to 4 khz octave band noise at 102 db spl (group 1, n=5); those conditioned with 1 khz oct...

OBJECTIVE To determine the initial Brainstem Auditory Evoked Response (BAER) abnormalities in neonates with hyperbilirubinemia and the possible reversibility of abnormal BAER after therapy. DESIGN Prospective cohort study. SETTING Tertiary care hospital. SUBJECTS 30 term neonates with hyperbilirubinemia (S. bilirubin < 15 mg/dl) as cases and 25 normal term neonates as controls. METHODS ...

Because of the nature and location of the lesion in central pontine myelinolysis, considerable difficulties in diagnosis may arise. Computed tomography (CT) and brainstem auditory-evoked potentials are useful in following the spread and regression of the pontine lesion. The correlation between clinical evolution, serial CT scans, and brainstem auditory-evoked potentials is considered in a patie...

Auditory processing impairments negatively impact language learning, the ability to listen effectively in noisy environments, and the development of reading skills. Behavioral assessments of auditory processing provide valuable insight into auditory function but lack information about the biological health of the auditory pathway, and can be complicated by comorbid disorders, alertness, and mot...

Musicians have a variety of perceptual and cortical specializations compared to non-musicians. Recent studies have shown that potentials evoked from primarily brainstem structures are enhanced in musicians, compared to non-musicians. Specifically, musicians have more robust representations of pitch periodicity and faster neural timing to sound onset when listening to sounds or both listening to...
