introduction: one of the most common pathologies in neonates is hyperbilirubinemia, which is a good marker for damage to the central nervous system. the sensitivity of the auditory system to bilirubin has been previously documented, with much discrepancy in its effects on auditory brainstem response results. thus the objective of this study was to evaluate the effects of hyperbilirubinemia on a...

  Background :Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds.   Methods : Concurrent auditory...

Introduction: Tinnitus is a perception of sound without external source. For complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. Temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing.   Materials and Method...

the authors used high-resolution computed tomography (hrct) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. in six children the malformations were bilateral. the malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. analyzing anatomical details and pathological changes on hrct axial sections ...

background and aim: tinnitus is perception of sound in absence of external source. reaction time is the time between sensory stimuli and a behavior. alternation of auditory reaction time has been shown in the literature in patients with tinnitus. this study has investigated the auditory reaction time in quiet and noise to different frequencies. methods: fifteen subjects with chronic tinnitus pa...

Many behaviors are learned through trial and error by matching performance to internal goals. Yet neural mechanisms of performance evaluation remain poorly understood. We recorded basal ganglia-projecting dopamine neurons in singing zebra finches as we controlled perceived song quality with distorted auditory feedback. Dopamine activity was phasically suppressed after distorted syllables, consi...

Auditory processing disorder (APD) and attention-deficit hyperactivity disorder (ADHD) present overlapping symptomatology. Previous research has demonstrated that professionals use different behavioral descriptors to characterize APD and ADHD combined and predominantly hyperactive-impulsive subtypes, which present with hyperactivity, impulsivity, and inattention. The present study extends this ...

 Background: The purpose of the present study was to evaluate the psychometric properties (validity and reliability) of the Persian version of the Sustained Auditory Attention Capacity Test in children with attention deficit hyperactivity disorder. Methods: The Persian version of the Sustained Auditory Attention Capacity Test was constructed to assess sustained auditory attention using the meth...

We examined sensory-processing disorder (SPD) in children with cochlear implants and explored the relationship between SPD and duration of hearing loss or duration of cochlear implant use. Caregivers of 30 children completed the Sensory Profile Questionnaire (SPQ). Seventy percent of the children showed "at-risk" or "different" behaviors in one or more of five categories of the SPQ: auditory, v...

This paper describes the integration of articulated motion with auditory and visual sensory information that enables a humanoid robot to achieve certain reflex actions that mimic those of people. Reflexes such as reach-and-grasp behavior enables the robot to learn, through experience, its own state and that of the world. A humanoid robot with binaural audio input, stereo vision, and pneumatic a...
