Some electrical engineers design the giant dynamos and transmission lines that power society. Others apply their prowess to electronics in cars and televisions, or — still smaller — the microprocessors in phones and watches. Montana State University’s Anja Kunze, assistant professor in the Department of Electrical and Computer Engineering, studies the tiny electrochemical signals that […]Continue Reading ...
Potentially lethal heart conditions may become easier to spot and may lead to improvements in prevention and treatment thanks to innovative new software that measures electrical activity in the organ. The heart’s pumping ability is controlled by electrical activity that triggers the heart muscle cells to contract and relax. In certain heart diseases such as […]Continue Reading ...
Engineers and researchers at the University of California, Berkeley have developed a neurostimulator that can act as a pacemaker within the human brain. This device could detect the electrical currents within the brain and also deliver brain stimulation into the brain. This form of neurological stimulation could help patients with epilepsy and Parkinsonism, the team […]Continue Reading ...
A new, low-cost wound dressing developed by University of Wisconsin-Madison engineers could dramatically speed up healing in a surprising way. The method leverages energy generated from a patient’s own body motions to apply gentle electrical pulses at the site of an injury. In rodent tests, the dressings reduced healing times to a mere three days […]Continue Reading ...
Electrodes are placed on the patient’s chest area to record cardiac electrical activity – e.g. to determine whether the heart rhythm is so irregular that treatment is required; a type of medical examination for which ECG serves well as a diagnostic tool. Not quite so when it comes to examining fetal cardiac electrical activity – […]Continue Reading ...
August 23, 2018 Electrical stimulation of the brain and spinal cord may help treat the symptoms of rare movement disorders called neurodegenerative ataxias, according to a study published in the August 22, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology. There are several types of these disorders, which can […]Continue Reading ...
Can electrical stimulation improve the brain’s ability to form memories during deep sleep? That’s what UAlberta neuroscientists are trying to find out. Credit: University of Alberta When it comes to remembering, brain-wave patterns during deep—or slow-wave—sleep could play a critical role, according to a new study by University of Alberta neuroscientists. “During slow-wave activity, brain […]Continue Reading ...
WEDNESDAY, June 7, 2017 (HealthDay Information) — An electrical surprise is an ceaselessly overpassed danger to swimmers, a security knowledgeable warns. “Electrical surprise drowning can happen in any recent frame of water,” mentioned Donald Burke, director of the College of Alabama at Birmingham’s Complicated Protection and Engineering Control program. “Anyplace you might have software that […]Continue Reading ...
Electrical stimulation of the brain is common practice in neuroscience research and is an increasingly common and effective clinical therapy for a variety of neurological disorders. However, there is limited understanding of why this treatment works at the neural level. A paper published by Takashi D. Y. Kozai, assistant professor of bioengineering at the University […]Continue Reading ...
Scientists have plenty of ways to watch as individual neurons in a brain fire, sending electrical signals from one to the next, but they all share a basic problem. Each method, whether it involves electrical probes, chemical agents or genetic modifications, is in some way more invasive than neuroscientists would like. That may soon change. […]Continue Reading ...
The glass container is filled with a gas of cesium atoms which respond to the magnetic field from the heart. The magnetic field is detected using laser light which is transmitted through the cesium atoms.

Researchers from the University of Georgia have replicated the effects of traumatic brain injury (TBI) and electrically stimulated neural recovery, using stem cell-derived neurons grown in a petri dish. Image Credit: Okrasyuk / Shutterstock The study, which has recently been published in Nature Scientific Reports, has important implications for the understanding and treatment of TBIs. […]Continue Reading ...
June 27, 2018 When migraine sufferers see the tell-tale squiggly lines, light flashes and blind spots of a migraine aura, they prepare for a migraine. When researchers see the brain image of an aura, they try to figure out what causes it and if there is a way to stop the start of the migraine. […]Continue Reading ...
April 18, 2018 Using computer models and laboratory rats, Johns Hopkins researchers have demonstrated that “direct electrical current” can be delivered to nerves preferentially, blocking pain signals while leaving other sensations undisturbed. The researchers say the experiments advance the search for improved implantable devices able to treat chronic pain that is due to peripheral nerve […]Continue Reading ...
WEDNESDAY, June 7, 2017 — An electrical surprise is an continuously lost sight of danger to swimmers, a security skilled warns. “Electrical surprise drowning can happen in any contemporary frame of water,” stated Donald Burke, director of the College of Alabama at Birmingham’s Complex Protection and Engineering Control program. “Any place you will have instrument […]Continue Reading ...
