Background and Objective: Binaural interaction component has been seen to be effective in assessing the binaural interaction process in normal hearing individuals. However, there is a lack of literature regarding the effects of SNHL on the Binaural Interaction Component of ABR. Hence, it is necessary to study binaural interaction occurs at the brainstem when there is an associated hearing impai...

The effects of 10%, 30% and 50% nitrous oxide on visual, auditory and somatosensory evoked potentials were studied in seven healthy volunteers. The evoked potentials were averaged from the electroencephalogram following repeated peripheral sensory stimulation of the appropriate modality. Latencies and amplitudes of the resulting potentials were measured and compared with control values. In five...

Infants with auditory neuropathy and possible hearing impairment are being identified at very young ages through the implementation of hearing screening programs. The diagnosis is commonly based on evidence of normal cochlear function but abnormal brainstem function. This lack of normal brainstem function is highly problematic when prescribing amplification in young infants because prescriptive...

Mercury is known to alter neuronal function and has been shown to cross the placental barrier. These experiments were undertaken to examine if gestational exposure to mercury vapor (Hg(0)) would result in alterations in sensory neuronal function in adult offspring. Dams were exposed to 0 or 4 mg/m(3) Hg(0) for 2 h/day from gestational days 6-15. This exposure paradigm has been shown to approxim...

background and aims: this is a pilot study investigated the prevalence of hearing impairment and the impact of the known risk factors for hearing loss on infants at risk born in kuwait. methods: two hundred infants with risk of hearing impairment who met the joint committee on infants hearing (1990) criteria were screened. all newborns were included in this study if they had hospital stay for m...

BACKGROUND To characterize the findings of brainstem auditory evoked potential in HIV-positive individuals exposed and not exposed to antiretroviral treatment. MATERIAL AND METHODS This research was a cross-sectional, observational, and descriptive study. Forty-five HIV-positive individuals (18 not exposed and 27 exposed to the antiretroviral treatment - research groups I and II, respectively...

Sound localization along the azimuth depends on the sensitivity of binaural nuclei in the auditory brainstem to small differences in interaural level and timing occurring within a submillisecond epoch and on monaural pathways that transmit level and timing cues with high temporal fidelity to insure their coincident arrival at the binaural targets. The soma and axons of these brainstem neurons a...

healthy newborns due to its lower false-positive and referral rates, high specificity, and also its’ ability to diagnose auditory neuropathy spectrum disorder combination with Transient Evoked Otoacoustic Emissions test. On the other hand, the test time can be a disadvantage. With technological advancements, a new generation Automated Auditory Brainstem Response has been developed which is fast...

background and aim: kawasaki disease (kd) is an acute childhood febrile illness with world­wide incidence and the highest incidence occurs in asian children, with coronary arteritis being the main complication. sensorineural hearing loss (snhl) has also been described as a comp­lication of kd in several articles. the aim of this study was to evaluate the prevalence of snhl in patients with kd t...

Background: Auditory evoked potentials (AEPs) were recorded to examine the neurophysiological correlates of four mental states described in ancient yoga texts. These are (i) focused attention (dharana), (ii) contemplation (dhyana) (iii) random thinking (cancalata) and (iv) non meditative focused thinking (ekagrata). The auditory evoked potentials allowed changes from the periphery (cochlear nuc...
