The ovarian hormones fluctuate during the menstrual cycle in women. Such fluctuation of sex hormones, in particular estrogen, is believed to affect the central conduction time in auditory function as well as the language lateralization in cognitive function. However, findings are inconsistent. The underlying mechanisms are also unclear. This paper examined if there was any relation between the ...

Congenital deafness results in abnormal synaptic structure in endings of the auditory nerve. If these abnormalities persist after restoration of auditory nerve activity by a cochlear implant, the processing of time-varying signals such as speech would likely be impaired. We stimulated congenitally deaf cats for 3 months with a six-channel cochlear implant. The device used human speech-processin...

introduction: high frequency alternating currents is a safe, reversible and selective method for nerve conduction block that has been under study during the last decade as a treatment for the diseases involving abnormal neural impulses. however, reducing the stimulus amplitude, and the undesired onset response, as well as optimizing the stimulus parameters for more effective block is still unde...

IT MAY BE CONCLUDED FROM THE RESULTS OBTAINED IN THESE EXPERIMENTS : 1. That stimulation of the right vagus nerve in the dog usually causes arrest of all the chambers of the heart. 2. That stimulation of the left vagus nerve exerts a moderate negative chronotropic effect on the auricles. 3. That stimulation of the left vagus nerve has a profound effect on the conduction of impulses over the aur...

The authors present a technique to perform nerve conduction study in armadillos (D. novemcinctus) and suggest that 66.17 m/s could be the mean normal nerve conduction velocity for the sciatic nerve, a parameter that could be used for assessment of the peripheral nervous system in this animal, considered the choice for experimental development of leprosy neuropathy and even in other peripheral n...

Median and ulnar nerves were evaluated using established nerve conduction techniques in a control population and in a population of patients with neuropathy. Motor and sensory residual latencies were obtained. The main contributor to the latencies was slowing of the nerve conduction in the smaller attenuated nerve fibres of the hand and fingers.

Hopf's technique was used to measure motor nerve conduction velocity of fibres in the deep peroneal nerve in clinical conditions where damage to the peripheral nervous system was probable. A particular distribution of motor nerve fibre conduction velocity was shown by the analysis of the findings in some of the groups investigated, illustrating the advantages of this method as compared with rou...

INTRODUCTION Presently, there are few studies addressing the subject of peripheral neuropathy in patients with chronic obstructive pulmonary disease (COPD). Consequently, there is a dearth of evidence and awareness of subclinical neuropathy in stable COPD patients with no significant hypoxaemia, particularly in the age group of 40-60 years. The present study was designed to evaluate the subclin...

We examined the effects of pesticides on the central and peripheral nervous system in the setting of a tobacco farm at a developing country. Maximal motor and sensory nerve conduction velocities (MCV and SCV, respectively) in the median, sural and tibial nerves, postural sway, and brain-evoked potentials (auditory event-related and visual-evoked potentials) were measured in 80 male tobacco farm...
