🧠🗣️BCI Award 1st place winner 2025: An Inner Speech Neuroprosthesis

What if people with paralysis could communicate at conversational speed — without attempting to physically speak? This work shows that purely imagined speech can power high-performance communication BCIs.

🧠 Highlights
• Decodes inner (imagined) speech directly from motor cortex
• Real-time RNN + language model decoding
• Up to 145 words/min (true conversational speed)
• Low error rates: 14% (50-word) and 26% (125k-word vocabulary)
• More comfortable and less fatiguing than attempted speech
• Includes safeguards to protect private, unintended inner speech

💡 Why it matters
Inner speech BCIs enable fast, natural, and private communication for people with ALS or stroke — overcoming key limitations of attempted-speech systems.

The video showcases the integration of a 32-channel EEG recording (left) with 16/16 fNIRS (right) optodes 😍😍 The EEG data is captured using a g.HIamp and active g.SCARABEO electrodes, housed in a g.GAMMAcap alongside 16 senders and 16 detectors from NIRx. The arrangement of optodes and EEG electrodes is meticulously designed around the sensorimotor cortex to capture left and right-hand movements.

Initially, the data acquisition process begins with the initiation of g.Recorder for capturing data from all 32 EEG channels, and Aurora is activated to acquire data from the fNIRS channels. Once both EEG and fNIRS recordings demonstrate high quality, the g.tec paradigm presenter is employed to conduct experiments on the same computer 🦊🦊 In this scenario, users are instructed to relax, and after a brief period, an arrow directs either left or right, prompting the user to imagine the corresponding hand movement. Precisely when the instruction is given, a trigger signal is sent to g.Recorder and Aurora via software commands with extremely high time resolution 🦊🦊🦊

Several noteworthy aspects are evident in the video:
👉The EEG data is exceptionally clean, attributed to the use of active electrodes combined with the over-sampling and anti-aliasing capabilities of g.HIamp.
👉The fNIRS signals are clean and stable, originating from the NIRx system.
👉Both signals are flawlessly acquired due to the meticulous assembly in the cap.
👉All software runs on a single computer, streamlining the experimental setup.
👉No additional software packages or external computers are required to execute the experimental paradigm.
👉Every component operates on the same computer, eliminating the need to transmit TTL pulses via external ports. This results in fewer cables and minimized delays and jitters.
👉Both EEG and fNIRS data are stored on the computer for subsequent offline analysis.

Unlocking New Insights with sEEG for Seizure Localization and Functional Brain Mapping from Kai Miller and Mayo Clinic.

Stereoelectroencephalography (sEEG) is now the go-to method for pinpointing seizure onset zones (SOZs) when imaging, semiology, and scalp EEG results are inconclusive. By implanting sEEG electrodes, clinicians can test SOZs and determine the best course of treatment—be it resection, laser ablation, or neurostimulation. In cases where SOZs overlap with eloquent brain regions, avoiding resection is crucial.

Michael Jensen, Kai Miller, Dora Hermes and their team present a new approach that uses task-based electrophysiological changes in sEEG to map movement and speech areas in both pediatric and adult epilepsy patients. This novel method reliably identifies functional regions, supporting more precise therapeutic decisions. The experiments were conducted with g.HIamp.

✔️g.HIamp is a 24 Bit biosginal amplifier with 256 ADCs for a perfect synchronization of all EEG channels. Each device has 4 processors included to perform a very high oversampling and ultra-steep anti-aliasing filtering to increase the signal to noise ratio.
✔️g.HIamp is the only device on the market that allows you to acquire ultra-high gamma activity up to 1 kHz. In includes ultra-steep anti-aliasing filters and ultra-high oversampling to reduce the noise floor dramatically. Otherwise the tiny signals are just covered in the noise floor of the amplifier.
✔️FDA cleared, CE certified medical product

🧠⌨️ An intuitive, bimanual, high-throughput QWERTY touch typing neuroprosthesis for people with tetraplegia

What if people with paralysis could type as naturally and quickly as anyone else — just by attempting finger movements? This project brings that vision to life.

🧠 Highlights
• Provides a bimanual QWERTY keyboard interface controlled by attempted finger movements
• Uses a recurrent neural network (RNN) to decode neural signals into characters in real-time
• High throughput: up to 110 characters per minute, 22 words per minute, with a 1.6% word error rate
• Requires only ~30 calibration sentences to achieve accurate decoding
• Works for participants with ALS or high cervical spinal cord injury, including those unable to use eye-gaze or speech-based systems
• Typing is self-paced, intuitive, and familiar, leveraging memory of standard keyboard layouts

💡 Why it matters
This iBCI typing neuroprosthesis provides fast, free-form digital communication for individuals with tetraplegia. By mimicking natural finger movements, it offers a clinically viable, easy-to-learn, and high-accuracy solution, surpassing current state-of-the-art hand motor iBCI systems and offering independence and privacy in communication.

g.tec medical engineering Austria

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.
