Interictal or ictal discharges are the basis of EEG interpretation when seizure localization is the goal, but a new report suggests an alternative. It has been known for over 40 years that, when DC recordings are made, seizures may be associated with localized, very slow, sustained voltage changes, which do not oscillate (ictal DC shift).1 These voltage changes occur more or less simultaneously...

Methods In 6 female Goettingen minipigs (weight 22–47 kg), 5 of which had been intoxicated with 1-methyl-4-phenyl1,2,3,6-tetrahydropyridine (MPTP), a unilateral electrode for chronic stimulation was placed in the subthalamic area. Correct localization of the electrode was verified by peroperative MRI-scan and examined by autopsy at study-termination after 12-14 months of stimulation-treatment. ...

let  $varpi$ be a representation of the homogeneous space $g/h$, where $g$ be a locally compact group and  $h$ be a compact subgroup of $g$. for  an admissible wavelet $zeta$ for $varpi$  and $psi in l^p(g/h), 1leq p

A novel chemically modified electrode containing Prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. The electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. The film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. Results showed at bare GC electrode, a...

This article proposes a novel active localization method based on the mixed polarization multiple signal classification (MP-MUSIC) algorithm for positioning a metal target or an insulator target in the underwater environment by using a uniform circular antenna (UCA). The boundary element method (BEM) is introduced to analyze the boundary of the target by use of a matrix equation. In this method...

a simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (gce/cooxnps) for determination of butylated hydroxyanisole is presented here. the nanoparticles were fabricated by electrodepositing method. the modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in ph 12.0 phosphate buffer solution (pbs...

a fast and simple voltammetric method for the determination of methimazole in pharmaceutical products was reported. a glassy carbon electrode was pretreated by anodization at +1.75 v (vs. sce) for 5 min, followed by potential cycling in the range of 0.3-1.3 v (20 cycles). the pretreated electrode showed an excellent electrocatalytic effect on the oxidation of methimazole. compared with untreate...

Background: Studies of deep brain stimulation (DBS) require accurate electrode localization and image registration. We used anatomical fiducials to investigate registration errors in patients who underwent subthalamic nucleus (STN) DBS for Parkinson’s disease (PD). Methods: conducted a retrospective analysis bilateral STN PD. Pre post operative MRI scans were non-linearly normalized standard te...

Cortical areas that control ear movement have not been reported in humans. We describe a rare case in which ear auricle movement was induced by extraoperative electrical cortical stimulation. A 21-year-old man with intractable localization-related epilepsy was admitted for presurgical evaluation. Subdural electrodes were implanted over the right temporal and frontal regions. Tonic upward contra...

This paper shows that a highly deformable capacitor made of a soft dielectric and two conformal electrodes can switch between two states discontinuously, by a first-order transition, as the total charge varies gradually. When the total charge is small, it spreads evenly over the area of the capacitor, and the capacitor deforms homogeneously. When the total charge is large, it localizes in a sma...
