Noninvasive Nerve Stimulator May Ease Sleep Apnea
Using a transcutaneous electrical neurostimulator (TENS) machine may reduce the severity of obstructive sleep apnea (OSA) in people not adhering to continuous positive airway pressure (CPAP) therapy, a small single-center randomized trial suggested. After 3 months, the difference in apnea/hypopnea index (AHI) scores in unadjusted analysis significantly favored the TENS group versus the usual-care group […]
Neuromodulation of the Peroneal Nerve Safe for Overactive Bladder
Electrical transcutaneous neuromodulation (eTNM) of the peroneal nerve led to fewer side effects compared with solifenacin (Vesicare) in the treatment of overactive bladder, a randomized trial showed. Among 76 treatment-naive women randomized 2:1 to peroneal eTNM or solifenacin, 12% versus 48% reported a treatment-related adverse event (TRAE; P<0.001), reported Jan Krhut, MD, PhD, of University […]
Spiral wave teleportation theory offers new path to defibrillate hearts, terminate arrhythmias
A spiral wave of electrical activity in the heart can cause catastrophic consequences. One spiral wave creates tachycardia — a heart rate that’s too fast — and multiple spirals cause a state of disorganized contraction known as fibrillation. Researchers from the Georgia Institute of Technology offer a new method to disrupt spiral waves that uses […]
Quantum sensor can detect electromagnetic signals of any frequency: Engineers expand the capabilities of these ultrasensitive nanoscale detectors, with potential uses for quantum computing and biological sensing.
Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting a few specific frequencies of these fields, limiting their usefulness. Now, researchers at MIT have developed a method to enable such sensors to […]
‘Smart’ greenhouses could slash electricity costs
A new, internet-connected lighting system for greenhouses could sharply reduce a farmer’s electrical bill, according to a study by University of Georgia researchers. Recently published in Plants, the study showed that a predictive lighting control system could optimize lighting for plants by predicting sunlight and only running the lights when needed. The data showed that […]
Novel quantum effect discovered in naturally occurring graphene: International research team finds atomically-thin carbon generates its own magnetic field
Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and “quantised” (meaning that it changes in discrete steps rather than continuously). This quantisation of electrical resistance normally occurs […]
Directly into the brain: A 3D multifunctional and flexible neural interface: Novel design of brain chip implant allows for measuring neuronal activity while simultaneously delivering drugs to the implant site
Being able to measure the electrical activity of the brain has helped us gain a much better understanding of the brain’s processes, functions, and diseases over the past decades. So far, much of this activity has been measured via electrodes placed on the scalp (through electroencephalography (EEG)); however, being able to acquire signals directly from […]
New AI algorithm to improve brain stimulation devices to treat disease
For millions of people with epilepsy and movement disorders such as Parkinson’s disease, electrical stimulation of the brain already is widening treatment possibilities. In the future, electrical stimulation may help people with psychiatric illness and direct brain injuries, such as stroke. However, studying how brain networks interact with each other is complicated. Brain networks can […]
Encephalitis Symptoms, Treatment, Diagnosis & Definition
Encephalitis Symptoms & Signs Seizures A seizure is the uncontrolled electrical activity in the brain, which may produce a physical convulsion, minor physical signs, thought disturbances, or a combination of symptoms. The type of symptoms and seizures depend on where the abnormal electrical activity takes place in the brain, what its cause is, […]
