Real-Time fNIRS Analysis for BCI and Neurofeedback

Turbo-Satori is an advanced real-time fNIRS analysis platform developed by Brain Innovation exclusively for NIRx instruments. It is optimised for neurofeedback and Brain-Computer Interface (BCI) research, and is compatible with all NIRx platforms — from lab-based NIRScout to the fully mobile NIRSport — with no additional hardware required.

Data acquisition integrates seamlessly with NIRStar or Aurora software via the Lab Streaming Layer (LSL) protocol. The analysis pipeline is fully customisable for each experimental design, calculating changes in oxy- and deoxy-haemoglobin concentrations followed by block averages, GLM, SVM classification, and statistics.

Key Features

Topographic channel selection. Preprocessing including movement artefact correction and GLM. Real-time statistics: T-values, beta values, channel correlation, and averaging. A new rsl-GLM-based filter uses confound predictors from GLM settings to clean the data in real time. The updated interface offers greater flexibility and macOS compatibility.

FAQ

What is Turbo-Satori used for?

Turbo-Satori is used for real-time online fNIRS analysis, specifically for neurofeedback and Brain-Computer Interface (BCI) research. It enables fast, result-driven high-quality fNIRS analysis during live recordings.

Which NIRx systems is Turbo-Satori compatible with?

Turbo-Satori is compatible with all NIRx platforms, including the lab-based NIRScout and the mobile NIRSport systems. No additional hardware is required beyond the existing NIRx setup.

How does Turbo-Satori receive data in real time?

Turbo-Satori uses the Lab Streaming Layer (LSL) protocol, implemented in NIRStar or Aurora acquisition software, to import raw fNIRS data for real-time processing.

What analysis features does Turbo-Satori offer?

Features include GLM, SVM classification, block averages, movement artefact correction, real-time T-values, beta values, channel correlation, and the new rsl-GLM-based filter for confound removal.

Is Turbo-Satori suitable for beginners?

Yes. The user-friendly interface is designed to make advanced processing features accessible to students and researchers who are new to fNIRS data analysis.
