Trimodal approach

Combining 3 techniques to boost brain-imaging precision

Researchers report that they have developed a method to combine three brain-imaging techniques to more precisely capture the timing and location of brain responses to a stimulus. Their study is the first to combine the three widely used technologies for simultaneous imaging of brain activity. The work is reported in the journal Human Brain Mapping. The new "trimodal" approach combines…

high-density EEG

A deeper look inside the brain

Understanding the source and network of signals as the brain functions is a central goal of brain research. Now, Carnegie Mellon engineers have created a system for high-density EEG imaging of the origin and path of normal and abnormal brain signals.

Glaucoma detection with brain-based VR device

A wearable brain-based device called NGoggle that incorporates virtual reality (VR) could help improve glaucoma diagnosis and prevent vision loss. Duke University researchers funded by the National Eye Institute (NEI) have launched a clinical study testing the device in hopes that it could decrease the burden of glaucoma, a major cause of blindness in the U.S. The device consists of head-mounted…

Parents’ brains ‘sync up’ with their infant’s when they play together

When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research, published in the open-access journal PLOS Biology, by Dr Sam Wass of the University of East London in collaboration with Dr Victoria Leong (Cambridge University and Nanyang…

Behaviour prediction

The psychology of taking risks

An anxious person will avoid risks whenever possible. This in itself is not exactly a surprise. However, researchers have found a way to visualize this process in the brain - with interesting implications for behaviour prediction. A team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg, Germany and Victoria, Canada they conducted an…

Deaf children learn words faster than hearing children – here's why

Each year up to two thousand hearing impaired children are born in Germany. For some of them a cochlear implant can offer relief. So far, it was not clear which processes take place in these children when they start to learn language later than their contemporaries with normal hearing—and why they differ in their success to reach a normal level of language. The Max Planck Institute for Human…

Nano-scale diagnostics

Researchers are developing a ‘Lab-on-skin’ to monitor biomarkers

Move over, lab-on-a-chip and lab-on-paper. There’s a new diagnostic technology in research labs that is gaining credibility. It is called lab-on-skin technology and some scientists are quite excited about how it might be used for a variety of clinical purposes. A recent story published in ACS Nano titled, “Lab-on-Skin: A Review of Flexible and Stretchable Electronics for Wearable Health…

Epilepsy

Minisensor is designed to warn of epileptic seizures

For epilepsy patients and attending physicians, it has been a challenge to correctly assess the frequency and severity of epileptic seizures without inpatient recording equipment. A consortium coordinated by the epileptologists of the University Hospital Bonn is now developing a mobile sensor that can detect seizures. A warning signal is designed to summon relatives or attending physicians to…

Using brain waves to steer a wheelchair

At the Joint Congress of European Neurology in Istanbul, researchers from Austria and Belgium have presented a study exploring innovative methods for communicating with coma patients. Their aim is to be able to communicate with patients by detecting brain activity even in people with inhibited consciousness.

MRI: Still the best tool for seizures

Anti-seizure medication is not successful in all patients, while in others such medication can have side effects. In recent years significant technical advances have delivered better imaging results, which, combined with growing demand for a surgical solution from patients whose medications do not control seizures, or those not wanting to take medication constantly, has led to an increase in…
