Controlling neural excitations may help prevent detrimental effects like those in stroke, say scientists

What do lasers, neural networks, and spreading epidemics have in common? They share a most basic feature whereby an initial pulse can propagate through a medium - be it physical, biological or socio-economic, respectively. The challenge is to gain a better understanding - and eventually control - of such systems, allowing them to be applied, for instance to real neural systems. This is the objective of a new theoretical study published in EPJ B by Clemens Bachmair and Eckehard Schöll from the Berlin University of Technology in Germany.

Researchers find that human eye can sense invisible infrared light under certain conditions

Any science textbook will tell you we can't see infrared light. Like X-rays and radio waves, infrared light waves are outside the visual spectrum.

Ohio State researchers study repetitive transcranial magnetic stimulation for stroke rehabilitation

Researchers at The Ohio State University Wexner Medical Center are trying to help patients who have suffered a stroke to improve arm movement by stimulating the brain using a device called a Transcranial Magnetic Stimulator (TMS). By using TMS to reduce brain activity on the side that was not injured by the stroke, the injured side may have a better chance of recovering.

New study investigates patient perspectives on deactivation of ICDs at the end of life

Most patients with implantable cardioverter defibrillators (ICDs)--small devices placed in a person's chest to help treat irregular heartbeats with electrical pulses, or shocks--haven't thought about device deactivation if they were to develop a serious illness from which they were not expected to recover.

New handheld probe can produce detailed images of blood vessels, other internal body parts

A new handheld probe developed by a team of university and industry researchers in the Netherlands and France could give doctors powerful new imaging capabilities right in the palms of their hands. The imaging system, which is described in a paper published in The Optical Society's open-access journal Optics Express, shrinks a technology that once filled a whole lab bench down to a computer screen and a small probe about the size of a stapler.

UW researchers successfully replicate direct brain-to-brain connection between people

University of Washington researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

New type of medical imaging technology could diagnose plaques

Researchers are close to commercializing a new type of medical imaging technology that could diagnose cardiovascular disease by measuring ultrasound signals from molecules exposed to a fast-pulsing laser.

Photoacoustics could become alternative to mammography or sonogram for breast cancer detection

One of the lines of research of OILTEBIA, a European science project coordinated by Universidad Carlos III de Madrid, is a method to detect breast cancer based on photoacoustics and which could become an alternative to mammography or sonogram.

New immuno-oncology drug helps body's own immune system to fend off cancer

According to an August 25 Reuters report, the U.S. Food and Drug Administration is likely to approve Merck & Co.'s highly anticipated immuno-oncology drug, pembrolizumab, as a treatment for melanoma well ahead of a late October deadline.

New technology holds potential to identify cardiac disease using video monitoring

To the careful observer, a person's face has long provided insight into what is going on beneath the surface. Now, with the assistance of a web camera and software algorithms, the face can also reveal whether or not an individual is experiencing atrial fibrillation, a treatable but potentially dangerous heart condition.

Researchers endow mice with greater touch sensitivity by striking brain rhythm

By striking up the right rhythm in the right brain region at the right time, Brown University neuroscientists report in Nature Neuroscience that they managed to endow mice with greater touch sensitivity than other mice, making hard-to-perceive vibrations suddenly more vivid to them.

French Ministry of Health approves financial support for Second Sight Argus II Retinal Prosthesis System

Second Sight Medical Products Inc. today announces that the French Ministry of Health has officially approved financial support for the Argus II Retinal Prosthesis System. Through the Forfait Innovation scheme, the French Government will pay for the first wave of groundbreaking treatment for 36 patients with severe to total sight loss due to retinitis pigmentosa (RP) in France.

Stimulating nerves in ear could improve heart health

Stimulating nerves in your ear could improve the health of your heart, researchers have discovered. A team at the University of Leeds used a standard TENS machine like those designed to relieve labour pains to apply electrical pulses to the tragus, the small raised flap at the front of the ear immediately in front of the ear canal.
