Comparisons of the Spatial Resolution between Disc and Tripolar Concentric Ring Electrodes
We compared the half sensitivity volume and the common spatial subspace decomposition of visual evoked potentials as measures of spatial resoulion between conventional disc electrodes and tripolar concentric ring electrodes with a computer simulation. The results suggest that tripolar concentric ring electrodes can achieve much higher spatial resolution than conventional disc electrodes.
متن کاملEvaluation of sternocleidomastoid muscle activity by electromyography recorded with concentric ring electrodes
The use of non-invasive methods for the study of respiratory muscle signals can provide clinical information for the evaluation of the respiratory muscle function. The aim of this study was to evaluate the electrical activity of the sternocleidomastoid muscle recorded superficially by means of a concentric ring electrode (CRE) in bipolar configuration. This sensor enhances the spatial resolutio...
متن کاملClinical Utility of Interictal High-Frequency Oscillations Recorded with Subdural Macroelectrodes in Partial Epilepsy
BACKGROUND AND PURPOSE There is growing interest in high-frequency oscillations (HFO) as electrophysiological biomarkers of the epileptic brain. We evaluated the clinical utility of interictal HFO events, especially their occurrence rates, by comparing the spatial distribution with a clinically determined epileptogenic zone by using subdural macroelectrodes. METHODS We obtained intracranial e...
متن کاملEffects of transcranial focal electrical stimulation via tripolar concentric ring electrodes on pentylenetetrazole-induced seizures in rats.
PURPOSE To study the effects of noninvasive transcranial focal electrical stimulation (TFS) via tripolar concentric ring electrodes (TCRE) on the electrographic and behavioral activity from pentylenetetrazole (PTZ)-induced seizures in rats. METHODS The TCREs were attached to the rat scalp. PTZ was administered and, after the first myoclonic jerk was observed, TFS was applied to the TFS treate...
متن کاملSafety of the Transcranial Focal Electrical Stimulation via Tripolar Concentric Ring Electrodes for Hippocampal CA3 Subregion Neurons in Rats
Epilepsy is a neurological disorder that affects approximately one percent of the world population. Noninvasive electrical brain stimulation via tripolar concentric ring electrodes has been proposed as an alternative/complementary therapy for seizure control. Previous results suggest its efficacy attenuating acute seizures in penicillin, pilocarpine-induced status epilepticus, and pentylenetetr...
