Visual electrophysiology is widely used in clinical ophthalmology. It is also of significant value in the objective assessment of visual function in adult and pediatric cataract patients and for the diagnosis of and research on retinal and visual pathway diseases. This article systematically reviews visual electrophysiology techniques, their applications in the diagnosis and treatment of adult ...

This work introduces a novel, unconditionally stable and fully coupled finite element method for the bidomain system of equations of cardiac electrophysiology. The transmembrane potential Φ(i)-Φ(e) and the extracellular potential Φ(e) are treated as independent variables. To this end, the respective reaction-diffusion equations are recast into weak forms via a conventional isoparametric Galerki...

Intracardiac pacemaker and defibrillator implantations were initially described a half century and a quarter century ago, respectively.1,2 Originally conceived as devices for the treatment of symptomatic bradycardia and sustained ventricular tachyarrhythmias, these therapies have subsequently been applied to the management of an increasing host of arrhythmia and other indications, including the...

INTRODUCTION The "Experimental Data and Geometric Analysis Repository", or EDGAR is an Internet-based archive of curated data that are freely distributed to the international research community for the application and validation of electrocardiographic imaging (ECGI) techniques. The EDGAR project is a collaborative effort by the Consortium for ECG Imaging (CEI, ecg-imaging.org), and focused on ...

Electrophysiology, which is the study of electrical properties biological tissues and cells, has become indispensable in modern clinical research, diagnostics, disease monitoring therapeutics. In this paper we present a brief history discipline how integrated circuit design shaped electrophysiology last few decades. We will discuss biopotential amplifier evolved from classical three-opamp archi...

In this study, we present the microfabrication and characterization of a transparent microelectrode array (MEA) system based on PEDOT:PSS for electrophysiology. The influence electrode dimensions impedance was investigated stability over time under physiological environment demonstrated. A very good transparency value obtained by our displaying one best transmittance values when compared to oth...

BACKGROUND Compared with fluoroscopy, the current imaging standard of care for guidance of electrophysiology procedures, magnetic resonance imaging (MRI) provides improved soft-tissue resolution and eliminates radiation exposure. However, because of inherent magnetic forces and electromagnetic interference, the MRI environment poses challenges for electrophysiology procedures. In this study, we...

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...
