speech delay with an unknown cause is a problem among children. this diagnosis is the last differential diagnosis after observing normal findings in routine hearing tests. the present study was undertaken to determine whether auditory brainstem responses to click stimuli are different between normally developing children and children suffering from delayed speech with unknown causes. in this cr...

hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...

The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

objectives: auditory brain stem response (abr) is a result of eight nerve and brain stem nuclei stimulation. several factors may affect the latencies, interpeak latencies and amplitudes in abr especially sex and age. in this study, age and sex influence on abr were studied. methods: this study was performed on 120 cases (60 males and 60 females) at akhavan rehabilitation center of university of...

background hearing capability plays a principal role on human's communication. noise-induced hearing loss (nihl) caused by exposure to high noise levels is a serious socio-economic problem in modern societies. nihl can either be reversible, resulting in a temporary threshold shifts (tts) or irreversible, resulting in a permanent threshold shifts (pts). pts is often confirmed in the time span of...

Background: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation and disruption of the brain net...

Catha edulis is an evergreen tree with psychotropic effects. The present work was conducted to evaluate the possible effects of the ethanolic extracts of Catha edulis leaves (ECE) on the electrical activity of 4 areas in the brain of male rabbits. Forty male rabbits weighting 2200-2500 g were divided into 4 groups. The electrical activity of motor, somato–sensory, occipital, and auditory ...
