A Cleveland Clinic study has detected significant changes in the electroencephalogram (EEG) brain activity patterns of patients receiving chemotherapy. The study may give scientific evidence of a condition commonly referred to as "chemobrain" – the fogginess that many patients experience while on chemotherapy. Patients with chemobrain often report short-term memory problems and difficulty concentrating. "The EEG study demonstrated a higher amplitude, or more brain activity in women,...
In 1619, the pioneering astronomer Johannes Kepler published Harmonices Mundi in which he analyzed data on the movement of planets and asserted that the laws of nature governing the movements of planets show features of harmonic relationships in music. In so doing, Kepler provided important support for the, then controversial, model of the universe proposed by Copernicus. In the latest issue of Biological Psychiatry, researchers at the University of California in San Diego suggest that...
New method offers automated way to record electrical activity inside neurons in the living brain Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice...
Excess brain electrical activity at night can impair learning and development, even in children without known epilepsy BOSTON, April 25, 2012 /PRNewswire-USNewswire/ -- Children with developmental delay or autism may have unrecognized epilepsy-like brain activity during sleep, report researchers at Boston Children's Hospital. These nighttime electrical spikes, detectable only on EEGs, occur even in some children without known epilepsy and appear to result from early strokes or...
Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another. New research at Washington University School of Medicine in St. Louis unveils some of the inner workings of certain channels involved in regulating electrical signals in nerve cells, relaxing muscle cells and “tuning” hair cells in the inner ear....
Researchers at the EPFL have discovered rules that relate the genes that a neuron switches on and off, to the shape of that neuron, its electrical properties and its location in the brain The discovery, using state-of-the-art informatics tools, increases the likelihood that it will be possible to predict much of the fundamental structure and function of the brain without having to measure every aspect of it. That in turn makes the Holy Grail of modelling the brain in silico—the goal of...
TORONTO, March 30, 2012 /PRNewswire/ -- Great things come in small packages, or at least that's what leading neurologists, physiatrists and clinicians are now discovering with the revolutionary Myoguide Needle EMG Guided Injection System. The breakthrough technology, which has just received 510(k) clearance from the United States Food and Drug Administration, gives practitioners a superior way to deliver targeted injections for musculoskeletal pain, spasticity, fibromyalgia, and...
CHICAGO and TOTOWA, N.J., March 23, 2012 /PRNewswire/ -- VectraCor, Inc. -- www.vectracor.com -- What if your doctor could tell you in real-time, with a non-invasive test as to whether or not you might be having an acute myocardial infarction (AMI) or in simpler terms, a heart attack? When the American College of Cardiology (ACC) meets on Saturday, March 24 in Chicago, VectraCor, an emerging medical device company for cardiovascular solutions, will announce that it has received FDA...
SAN DIEGO, March 20, 2012 /PRNewswire/ -- CareFusion announced today that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its new electrodiagnostic system, known as the Viking on Nicolet® EDX. The EDX system is a multi-modality device for monitoring and testing electrophysiological information from the human nervous and muscular system. (Logo: http://photos.prnewswire.com/prnh/20100706/CAREFUSIONLOGO) The new EDX system offers an intuitive,...
The mechanism involved in the detection of hyperosmolarity by TRP channels is clarified, with a newly discovered molecule preventing apoptosis. A large change in the volume of a cell, from its basal level, is detrimental to its health. Therefore, our cells are equipped with mechanisms to maintain their constant volume. When a cell detects an environmental change that will alter its volume, due to changes in the osmotic pressure, it will adjust its internal water content to counter these...

Electrocardiography, sometimes called ECG or EKG, is a measurement of the electrical activity of the heart as the linear process unfolds. With the use of electrodes that are attached to the skin, this non-invasive test can provide vast information as to the patient’s status. By leaving the electrodes attached, the patient’s status can be monitored over intervals of time and recorded on the device. This data can be sent electronically for consults about potential treatments without delay....
Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...
