background and aim: neonatal jaundice is one of the common causes of early sensorineural hearing loss and an important cause of deafness in children. auditory responses are the most sensitive parts of the nervous system to the toxic effect of bilirubin. this study was aimed to examine the effect of neonatal hyperbilirubinemia and its treatment on auditory brainstem responses (abr). methods: ...
background and aim: attention is an important cognitive process that is necessary for educational purposes. blind people are deprived from the most widely used human sense, the sense of vision. there are reports that blind individuals have a significantly better performance in attentional tasks, as compared with normal subjects. the purpose of this study was to evaluate sustained auditory atten...
The molecular basis of sensory hair cell mechanotransduction is largely unknown. In order to identify genes that are essential for mechanosensory hair cell function, we characterized a group of recently isolated zebrafish motility mutants. These mutants are defective in balance and swim in circles but have no obvious morphological defects. We examined the mutants using calcium imaging of acoust...
In recent years, deep neural networks (DNN) have demonstrated significant business impact in large scale analysis and classification tasks such as speech recognition, visual object detection, pattern extraction, etc. Training of large DNNs, however, is universally considered as time consuming and computationally intensive task that demands datacenter-scale computational resources recruited for ...
BACKGROUND Tinnitus is an auditory sensation characterized by the perception of sound or noise in the absence of any external sound source. Based on neurobiological research, it is generally accepted that most forms of tinnitus are attributable to maladaptive plasticity due to damage to auditory system. Changes have been observed in auditory structures such as the inferior colliculus, the thala...
As Roy Richard Grinker [1], an anthropologist and a father of an autistic girl, points out, despite autism being “a terrible, lifelong disorder”, it is “a better time than ever to be autistic” because a person with this diagnosis has access to more services and opportunities than ever before. Nevertheless, there are still a lot of problems to be solved and questions to be answered. One of them ...
hearing loss and meningitis were correlate in some aspects. hearing loss is the situation that can be shown in cochlear or retrocochlear defects. cochlear hearing loss is caused by inner or outer hair cell damage (however cochlear hearing loss has another causes, such as defect of arterial spiral ganglion, basilar and tectorial membrane) and retrocochlear hearing loss has neural origin and meni...
Abstaract Background and Aim: Tinnitus is a specific auditory sensitivity in which the patient hears nonexistent sounds. From neurological point of view, in majority of them increment in neural activity has been proposed characterized by increase in spontaneous firing rate in central auditory system. According to a hypothesis, tinnitus is a result of abnormal synaptic plasticity and reduced inh...
Background and purpose: Auditory-verbal memory decreases with age. One method to compensate this weakness is transcranial direct current stimulation. The current study investigated the effect of Anodal Transcranial Direct Current Stimulation on auditory-verbal memory performance of healthy elderly people. Materials and methods: In a randomized clinical trial, 42 healthy subjects with no histor...
In an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (MS), an audiometric evaluation was performed and auditory brainstem responses (ABRs) were obtained. Stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of MS. 24 (RO%) patients had an abnormal ABR along with c...
