The electrophysiology of smooth muscle
Initial investigations into the electrophysiology of smooth muscle were carried out by Bozler (1946) who studied the ureter, uterus and muscle of the intestine using external electrodes. He recorded action potentials similar to those which had been recorded from other excitable tissues during …

Image guidance in cardiac electrophysiology
Cardiac arrhythmias are characterized by a disruption or abnormal conduction of electrical signals within the heart. Treatment of arrhythmias has dramatically evolved over the past half-century, and today, minimally-invasive catheter-based therapy is the preferred method of eliminating arrhythmias. …

Sex Differences in Cardiac Electrophysiology
… We investigated the sex differences in cardiac electrophysiology with a focus on cardiac conduction and components of a common cardioplegia solution; we determined that there are electrophysiologic sex differences in response to both magnesium and mannitol. The sex substrates in three of the …

The Electrophysiology of Written Informal Language
<p>Language is an essential component of human behavior. It is ubiquitous, but more importantly, it is malleable and it is constantly changing. Part of the dynamic nature of informal communication is the introduction and adoption of new linguistic elements. Online communication provides a window …

Multi-Scale Modelling of Gastric Electrophysiology
… modelling framework for the study of gastric electrophysiology in health and disease. First, we have developed and validated two novel biophysically based models of Interstitial cell of Cajal and smooth muscle cell electrophysiology. Second, we have integrated the two cell models into a three …

X-LINKED RETINOSCHISIS ELECTROPHYSIOLOGY, MOLECULAR GENETICS AND TREATMENT
X-linked retinoschisis (XLRS) is a congenital progressive inherited retinal disease that affects the entire retina and is one of the more common causes of vision loss from retinal degeneration affecting young men,. The progression is variable but seems to be relatively stationary in the ages 6 to …

An intracardiac navigation interface for electrophysiology modeling tools
This thesis describes an interface that has been developed to assist in medical procedures. Several commercial systems are currently available each with their own strength and weaknesses and the goal of this interface is to leverage each of them. It is based upon a number of toolkits such as the …

Engineering Low Noise Organic Electrochemical Transistors for Electrophysiology Applications
… holds great potential for recording high quality electrophysiology signals is the organic electrochemical transistor (OECT). OECTs have been fabricated onto flexible substrates from biocompatible materials and have been shown to provide higher signal-to-noise ratio (SNR) than electrodes. Their …

Toward accessible evaluation of the electrophysiology of human vision
As photoreceptors in our retinas capture discrete photons, that energy is converted into an electrochemical signal which shoots back through the optic nerve and into our visual cortex. We can sample that signal as it's transmitted, by delivering specific stimuli and recording the aggregate response …

Development of extracellular electrophysiology methods for scalable neural recording
… models of neural circuits. Extracellular electrophysiology is a neural recording method that has been developed to record from large populations of neurons, but well-known problems with signal attribution pose an existential threat to the viability of further system scaling, as analyses of …

Blockade of Acetylcholine Receptors by Cobra Toxin Electrophysiology and Pharmacology
<p>Cholinergic transmission has been studied in the presence of a pure polypeptide toxin, of known amino-acid sequence, from cobra venom. For the frog sartorius myoneural junction, micropipette electrodes and on-line computer were used to show that the toxin specifically and irreversibly …

Keeping Pace with Interstitial Cells of Cajal: Modelling Gastrointestinal Electrophysiology
Gastrointestinal (GI) motility is coordinated by several cooperating mechanisms, including myogenic, neural and hormonal control systems. This thesis focuses on one of these mechanisms: an intrinsic bioelectrical activity called slow waves, which originates in pacemaker cells called interstitial …

Transparent neural interfaces for simultaneous electrophysiology and advanced brain imaging
Imaging and electrophysiology are the most fundamental tools in neuroscience research. On the one hand, optical imaging can target specific molecules with high spatial resolution *in vitro* and *in vivo*. Spectroscopic techniques like magnetic resonance imaging (MRI) can access deep regions of the …

Emotion word processing: evidence from electrophysiology, eye movements and decision making
A degree of confusion currently exists regarding how the emotionality of a textual stimulus influences its processing. Despite a wealth of research recently being conducted in the area, heterogeneity of stimuli used and methodologies utilized prevented general conclusion from being confidently …
