Near-infrared spectroscopy (NIRS) and electroencephalography (EEG) have recently provided fundamental new information about how the newborn brain processes innocuous and noxious somatosensory information. However, results derived independently from these two techniques are not entirely consistent, raising questions about the relationship between hemodynamic and electrophysiological responses in...

normal 0 false false false en-us x-none ar-sa background: the h-reflex is a useful electrophysiological procedure for evaluating the status of the peripheral nervous system, especially at the proximal segment of the peripheral nerve. the purpose of this study is to investigate the relation between triceps surae h-reflex and m- response latencies and thigh length in normal population, in order t...

Increasingly, neuroscientists are taking the opportunity to use live human tissue obtained from elective neurosurgical procedures for electrophysiological studies in vitro. Access to this valuable resource permits unique studies into the network dynamics that contribute to the generation of pathological electrical activity in the human epileptic brain. Whilst this approach has provided insights...

Abstract Background Electrophysiological techniques have been used for discriminating myoclonus from other hyperkinetic movement disorders and classifying the subtype. This study was carried out on patients with different subtypes of to determine electrophysiological characteristics anatomical classification etiologies. included 20 compared 30 control participants. all by somatosensory evoked p...

Characean algae have been a model plant for electrophysiology many decades, due to the large size of internodal cells and their robust recovery from invasive manipulation. The information gained them has provided template understanding groups. relative ability take up or export ions, including nutrients toxins, can be part explanation as why certain macrophytes occur preferably in nutrient-rich...

There are many environmentally important chemicals which exhibit potent effects on the nervous system. Examples include insecticides such as pyrethroids, DDT, cyclodienes, organophosphates and carbamates, and heavy metals such as mercury and lead. Since nerve excitation takes place in a fraction of a second, electrophysiological methods provide us with the most straightforward approach to the s...

Introduction: Antibiotic supplements are regularly used in neuronal culture media to control contamination however, they can interfere with the neuronal excitability and affect electrophysiological properties. Therefore, in this study, the effect of penicillin/streptomycin supplements on the spontaneous electrophysiological activity of hippocampal pyramidal neurons was examined. Methods: Electr...

This lecture focuses on the impact of classic and modern electrophysiological techniques on the diagnostic approach to patients with neuromuscular disorders, placing emphasis on the limitations of currently used techniques and on the future prospects of clinical neurophysiology. The refinement of old techniques together with the development of new ones will hopefully improve the diagnostic capa...
