The video demonstrates the seamless integration of a 32-channel EEG recording (left) with a 16/16 fNIRS (right) optode setup 🎥🧠

EEG signals are acquired using a g.HIamp amplifier and active g.SCARABEO electrodes, arranged in a g.GAMMAcap alongside 16 senders and 16 detectors from NIRx. Both EEG electrodes and fNIRS optodes are strategically positioned around the sensorimotor cortex to capture left- and right-hand motor imagery.

The data acquisition workflow begins with g.Recorder, which captures signals from all 32 EEG channels, while Aurora records the fNIRS signals. Once high-quality signals are confirmed from both modalities, the g.tec paradigm presenter is launched on the same computer to run the experiment 🖥️

During trials, participants are instructed to relax until prompted by an arrow pointing left or right, which cues them to imagine the corresponding hand movement. At the exact moment of instruction, a trigger signal is sent simultaneously to g.Recorder and Aurora, ensuring synchronization with extremely high temporal precision ⏱️

Key highlights from the video include:
👉 Exceptionally clean EEG data, thanks to active electrodes combined with the oversampling and anti-aliasing features of g.HIamp.
👉 Stable, high-quality fNIRS signals, reliably acquired via the NIRx system.
👉 Optimized integration in the cap, enabling both modalities to perform flawlessly together.
👉 Single-computer operation, where EEG, fNIRS, paradigm presentation, and triggering all run without additional hardware.
👉 No need for extra software packages, external machines, or TTL pulse cabling, reducing complexity, minimizing delay, and eliminating jitter.
👉 Complete data storage of both EEG and fNIRS recordings on the same computer, enabling efficient offline analysis.

Thanks to NIRx Medical Technologies!! Great things happen, just by doing it.

🧠 recoveriX Patient Interview – Real Stories, Real Progress 🎥✨

With over 25 years of experience in Brain-Computer Interface (BCI) technology, g.tec has developed recoveriX—a breakthrough neurorehabilitation system designed for patients with stroke, multiple sclerosis (MS), and Parkinson’s disease.

🌍 Used in more than 20 countries, recoveriX is medically certified, safe, and effective, helping individuals regain movement—even decades after diagnosis or injury.

How does recoveriX work?
🧠 Patients are asked to mentally imagine specific motor movements (6,000–8,000 repetitions).
⚡ The BCI system detects these imagined movements in real-time and activates functional electrical stimulation (FES) in the hand or foot.
🔄 This process re-establishes the connection between cognitive intention and motor ex*****on, allowing patients to move their limbs again.
✨ The moment a previously paralyzed hand moves for the first time in years is unforgettable—and often deeply emotional.

💬 “It’s never too late to start recovery. We've seen incredible improvements even 10, 20, or 30 years after a stroke.”

🚀 A Glimpse into the Origins of BCI

In 1999, g.tec's journey into the world of Brain-Computer Interfaces (BCI) began when Christoph Guger and Günter Edlinger presented their first BCI system at the BCI Conference in Rensselaerville. The story of this groundbreaking system started two years earlier when Christoph discovered National Instruments RTI800a PCI data acquisition boards and decided to build his own BCI.

Working alongside Prof. Gert Pfurtscheller at the University of Graz, Christoph connected the boards to a Compaq desktop computer, and with the help of a Simulink interface provided by Humusoft, he set up the feature extraction and classification algorithms. This marked the beginning of rapid prototyping for BCIs.

After intense experimentation in the lab, Christoph achieved 99% classification accuracy in real-time BCI experiments, proving the power of immediate calibration and feedback in EEG recordings—a significant departure from the months-long training that was common at the time.

This "Rapid Prototyping System" revolutionized BCI research and is now seen as a pivotal moment in the evolution of neurotechnology.

A special shout-out to Prof. Pfurtscheller who remained skeptical at first but was soon convinced of the system's capabilities after seeing its performance. The system's success led to its publication in IEEE Transactions and laid the foundation for the development of g.tec's BCI innovations.

🚴‍♂️ 5,000 km. 13 states. 4 time zones. 45°C desert heat.
Lukas Kaufmann took on the legendary Race Across America for the second time—the toughest bike race in the world—and claimed 2nd place again. 💪🔥

This year, we joined the challenge:
Using our Unicorn BCI Core 8, we monitored Lukas’ brain activity throughout the race.
🎯 Goal: Maximize recovery in the shortest possible time. Lukas slept only during truly restorative delta-wave deep sleep and was gently woken once he entered lighter sleep—making sure no precious race time was wasted in less effective phases.

While the new strategy didn’t bring the time advantage we hoped for, the neurodata we collected is invaluable—for the future of endurance sports and sleep optimization. 🧠⚡

No crashes, no injuries, unshakable determination:
Second start. Second place. Same fighting spirit. 🏆

g.tec started developing brain-computer interfaces (BCI) about 20 years ago, after presenting the first portable BCI system in 1999 at the BCI Meeting in Rensselaerville, New York. This device had an EEG amplifier within the floppy drive housing of an HP laptop system. From there on, BCI technology evolved rapidly:

In 1999, we demonstrated the first BCI session with 100 % accuracy using a motor imagery BCI system with Common Spatial Patterns. In 2007, we released the first commercial BCI for home use, called intendiX. This P300 speller could achieve 100 % accuracy after only 5 minutes of training. Later in 2013, code based VEPs allowed users to control a robotic device with an accuracy of 98 % in a continuous control task and play World of Warcraft. Around this time, g.tec also became more active with ECoG recordings, which have led to several publications and the cortiQ system. The high spatial resolution of ECoG recordings has made it possible to decode much finer finger movements than noninvasive recordings, and to analyze under-explored brain regions like the fusiform face area in real-time using high-gamma activity.

In 2014, g.tec introduced wireless dry and wet EEG recording systems using active electrodes. This major achievement is still boosting BCI performance and user experience worldwide by improving the signal to noise ratio and ease of use. But what does the future hold for brain-computer interfacing? There are many exciting new directions, and g.tec is focused on extending BCIs with non-invasive and invasive neuromodulation and stimulation technology to further increase accuracy and to broaden application areas.
