the biological effects of omega-3 and omega-6 fatty acids are determined by their mutual interactions. this interaction extremely affects various functions. lower consumption of omega-3 during gestation leads to various disorders, even in hearing. we aimed to assess the effect of low omega-3/omega-6 ratios on auditory nerve conduction. in this experimental study, the auditory brainstem response...

Dependence of nerve conduction velocity on factors like age, sex and temperature is well known. Effect of handedness on nerve conduction velocity has not been studied adequately. In this study correlation between handedness and motor as well as sensory conduction velocity of right as well as left median nerve was studied in 84 medical students in the age group between 17-21 years out of which 7...

Diabetes mellitus can affect both the peripheral and the central nervous system. However, central deficits are documented less well than peripheral deficits. We therefore compared the course of development of neurophysiological changes in the central and peripheral nervous systems in streptozotocin-diabetic rats. Sciatic nerve conduction velocities and auditory and visual evoked potentials were...

footdrop is a relatively common deficit among the neurological disorders, which has different causes with various levels of involvement in neuromuscular system, including central nervous system (brain cortex, spinal cord), fifth lumbar root, peripheral nerves and muscles. peroneal nerve injury at the fibular head has been reported to the most common cause of foot drop, which can be due to infar...

Congenital external auditory canal atresia is a disorder with a prevalence of one in 10 000-20 000 live births and is bilateral in one third of the patients. With a conductive hearing loss of 60 dB, even unilateral atresia restricts hearing related social skills. The degree of middle ear deformity may make reconstruction surgery impossible or too hazardous, thus bone-conduction hearing aids hav...

The audiological or physiological data showed that auditory neuropathy was due to the demylination disease in peripheral nerve, especially in auditory nerve. The aim of this study was to explore the changes of auditory function and auditory nerve pathology through establishing a guinea pig model with demyelinated peripheral nerve. The guinea pig model was established by immunizing guinea pigs w...

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...

determination of f-wave latency is a simple and valuable method in evaluating proximal part of peripheral nerves. the aim of this study was to determine the mean minimal peroneal f wave (f min) in healthy individuals. a total of 282 individuals were studied. the mean age was 45.6 years. the f min (± sd) for 564 peroneal nerves was 47.09 ± 4.51 ms. the f min for the age group of 20-45 and height...

Cochlear implants are electronic devices intended to restore the sense of hearing in deaf people by direct electrical stimulation of the auditory nerve fibres that are still present in the deaf inner ear. Unfortunately, the clinical outcome is not very predictable. In this study a computational model is presented that can predict the neural response to an arbitrary cochlear implant. It first co...
