Eye-tracking technology aims to measure the point of gaze or the movement of the eyes with eye tracking devices, often to study human behavior out of the lab. Researchers are often challenged when subjects do not respond honestly or accurately due to artificial environments or discomfort. If the research aims to study real-world behaviors, lab situations or observations can change each subject’s behavior, reducing the ecological validity of the data. Read more
Dave Thompson works as a technician in the LIVELab at the McMaster Institute for Music and The Mind (MIMM) in Hamilton, Canada. He studied Mathematical Science at McMaster University and is interested in computers and programming. First, he started working at another EEG lab as a programmer, which led to more work with EEG, signal processing and programming experiments. When he started to specialize in evoked responses from the brain for different sounds, he started working at the LIVELab. The LIVELab consists of a big theater with 106 seats and a dance studio. It is dedicated to developing a center for the scientific study of music, sound and movement and their importance in human health. We had the chance to talk with Dave about his work. Read more
Lena Perseus is 18 years old and alumna of the Alpine Mittelschule in Davos in Switzerland. For her final exam, she wrote a thesis about Brain-Computer Interfaces (BCI) where she shows the usability of BCIs in daily uses and how easy it is to control, communicate or draw via thoughts. She writes about patients with Locked-In syndrome who use BCI to be creative and to communicate. Within her work she equipped herself with a BCI, a Brain Painting program and started an experiment. The result is an impressive and critical analysis of the technical functionality of BCI that shows possible application fields and the Brain Painting software. We talked with Lena about her final thesis. Read more

If people measure biosignals, they are usually connected via cables to a computer or at least a notebook, which is also pretty bulky. By using a mobile device like an android based smartphone or tablet, along with a wireless system, biosignal acquisition can be much more portable. Signal acquisition could be performed nearly everywhere. A software framework was recently created for g.Nautilus, providing functionality to measure biosignals and do some basic processing like applying digital filters, estimating bandpower or calculating bipolar derivation.
The Cybathlon took first place on October 8th, 2016 at the ETH Zurich where people with disabilities competed side by side at the Brain-Computer Interface Race (BCI Race). Pilot Numa Poujouly from the Team BrainTweakers from École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland won Gold in the BCI Race using his brain waves to control an avatar along a racetrack on a virtual train. The game is called “BrainRunners” and was especially developed for the Cybathlon’s BCI Race. The Brain Tweakers have been using high-quality g.tec equipment. We talked with pilot Numa and Serafeim Perdikis, another member of the team, and asked them about their experiences. Read more
tDCS is a non-invasive method to stimulate the brain using constant, low current. This technology has been used in patients with brain injuries or psychiatric conditions like major depressive disorder. In addition, tDCS has been explored to alleviate memory deficits in Parkinson’s disease and Alzheimer’s disease, schizophrenia, and pain. Read more
Manuela Zehetner is a Physiotherapist with an expertise in Neurology. Since 2015, she has been working at g.tec medical engineering in Schiedlberg (Austria), where she uses the recoveriX system based on Brain-Computer Interface technology for stroke rehabilitation. Most of Manuela’s patients had a stroke years ago, but for the first time in a very long time, they improved their motor functions and can now move their arms better than before. We asked Manuela about her experience and success with recoveriX training.
TMS is a magnetic method to non-invasively stimulate the brain. This technology has been used to investigate the connectivity between the motor cortex and corresponding muscle groups for patients with brain damage. Read more
Wireless EEG and biosignal acquisition systems are becoming more important in Brain-Computer Interface research, especially when studies tend to take part in the field instead of in the lab. g.Nautilus is g.tec’s wireless EEG solution that is designed to be completely different from all other devices and sets a new standard of usability.
