Evoked Potentials are event-related activities that occurred as an electrical response from the brain to different sensory stimulations of nervous tissues. In this paper, auditory evoked potentials (AEP) brain responses were collected and examined. The data collection was done twice with three different levels of sound and frequencies. The auditory brain response data was extracted from the noi...
The generation mechanism of stimulus-evoked electro- and magnetoencephalographic (EEG & MEG) responses has remained controversial. One view holds that evoked responses are independent components, additive to ongoing brain activity. The other view holds that evoked responses are generated via stimulus-induced phase reorganization of ongoing brain activity. This issue has been commonly addressed ...
زمینه و هدف: با توجه به اهمیــت حــس شنوایــی در رشــد و تکامــل مهارت هــای کلامی و زبانی و ماهیت آسیب شنوایی در بیماری مننژیت به عنوان یک نوع از آسیب شنوایــی اکتسابــی، ایــن مطالعه بر ارزیابی شنوایــی و تشخیص زودهنگام کم شنوایــی در بیمــاری مننژیــت متمرکز شــده است. هدف از ایــن مطالعــه ارزیابی ادیولوژیــک شیــرخواران و کودکان مبتلا بــه بیماری مننژیــت در مرحله حاد و در هنگام بهبودی از ...
Seven patients with cerebrotendinous xanthomatosis (CTX) were studied by electrophysiological techniques. The percentages of abnormalities detected in nerve conduction studies and electroencephalograms were 28.6% (two patients) and 100%, respectively. All patients showed prolonged central conduction times in short latency somatosensory evoked potentials (SSEPs) by tibial nerve stimulation but n...
AVERAGING, when used to extract extremely small signals from relatively high levels of background noise, allows detection of evoked potentials at surprisingly large distances from the site of neuronal activity. In animals, volume-conducted potentials from brain-stem auditory structures can be recorded throughout the brain (Grinnell, 1963; Bullock et ah, 1968; Jewett, 1970) and even from the sca...
To evaluate the medicolegal relevance of middle latency responses for objectively approximating frequency-specific hearing levels in subjects with occupational hearing loss, we compared the middle latency response with the cortical response in 22 reliable subjects who had noise-induced hearing loss and were submitting claims for compensation and 21 subjects who had noise-induced hearing loss bu...
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...
