OBJECTIVE Adrenomyeloneuropathy (AMN) is an X linked metabolic disorder presenting with progressive spastic paraparesis in the third to fifth decade of life. Although peripheral neuropathy is also present in most patients, prominent pyramidal signs may make its clinical recognition difficult. The objective was to characterise the peripheral neuropathy in patients with AMN by nerve conduction st...

The auditory brainstem response (ABR) is a test widely used to assess the integrity of the brain stem. Although it is considered to be an auditory-evoked potential that is influenced by the physical characteristics of the stimulus, such as rate, polarity and type of stimulus, it may also be influenced by the change in several parameters. The use of anesthetics may adversely influence the value ...

It is well-known that diabetic patients develop peripheral and autonomic neuropathy, and recent review has also suggested the occurrence of central pathway abnormality in diabetics. In this article, we conducted the BAEP study on 61 cases of NIDDM and 11 cases of IDDM. Peak latency, interpeak latency (IPL) and peak amplitude of BAEPs were analyzed in each case. For further correlation, the moto...

The MiWaveS (Beyond 2020 heterogeneous wireless network with Millimetre Wave Small cell access and backhauling) project aims to contribute some key aspects to the ongoing definition of 5G, i.e. the next generation of wireless telecommunications [2]. Specifically, it will show how high-throughput and low-latency heterogeneous mobile networks, based on flexible spectrum usage of the millimetre wa...

Emerging vehicular safety applications require low latency communications and reliable packet dissemination for life saving safety messages. Significant developments have taken place over the past few years. IEEE WAVE and ISO CALM have been developed as international standards for ITS applications. Both WAVE and CALM support multichannel operations and use CSMA/CA as channel access mechanism. W...

PURPOSE The effect of isoflurane on the subcortical P14 component of the median nerve somatosensory evoked potential (SEP) is poorly known. We studied whether the P14 wave from the upper brainstem, recorded with a nasopharyngeal electrode, was attenuated at the isoflurane-induced EEG burst-suppression level. We also compared the effect of isoflurane on the P14, cervical N13 and cortical N20, N3...

Abstract Background F wave response, a late response obtained from motor nerve, can be influenced by various external factors like gender, temperature, height, weight, and limb length, hence it causes variation in the measured parameters. Since very few studies have studied impact of arm length on wave, this study was conducted to analyze relation between parameters consider importance during c...

OBJECTIVE To investigate the F wave parameters (F duration, F minimum latency, F maximum latency, F mean latency, F chronodispersion, and F persistence) of the tibial nerve with unilateral S1 radiculopathy. We evaluated the differences of these parameters between the affected and unaffected sides and also with the control group. METHODS The study was performed from September 2007 to January 2...

Reaction times (RTs) are substantially prolonged in schizophrenia patients, but the latency of the P3 component is not. This suggests that the RT slowing arises from impairments in a late stage of processing. To test this hypothesis, 20 schizophrenia patients and 20 control subjects were tested in a visual oddball paradigm that was modified to allow measurement of the lateralized readiness pote...

We congratulate Dr. Azarmina and colleagues on their study investigating the latency of visual evoked potentials (VEPs) among healthy females during and after menstruation.1 The authors found significantly increased latencies in pattern and flash VEP in their subjects. Their findings are particularly remarkable since the mean latency of the P100 wave was increased by approximately 20 ms (mean i...
