In addition, NIRSport2 is also used in conjunction with technologies such as electroencephalography (EEG), virtual reality (VR), and magnetic resonance imaging (MRI *)Provides specialized integration solutions.Advantages of NIRSport2

1. Modularity and Scalability

• Modular design with 8 light sources and 8 detectors as units

• Scalability, the number of light sources and detectors can be expanded from 8 to 80. The basic equipment configuration is 8 × 8 and 16 × 16.

• Up to 5 devices can be synchronized.

2. Signal quality

• Spring bracket with built-in short distance channel

• Optional next-generation APD detector with sensitivity as low as 5 fW.

• Exclusive automatic ultra fast light source and detector specific signal optimization technology.

• Variable tension spring bracket provides optimal scalp coupling and comfort.

• Short distance detectors with full head arrays can be provided.

• Probe level 9-axis accelerometer.

• The signal quality is guaranteed by our high-power LED, variable tension spring bracket that provides optimal scalp coupling, and high-performance SiPD or next-generation APD detectors. The measures to address extracranial interference sources include the recommended 8mm short-range detector (supporting full head array/placement) and probe level 9-axis acceleration measurement in literature.

3. Example of high-density arrangement

• Use 3 connected fNIRS/NIRSport2 devices to achieve high-density arrangement of 48 light sources and 48 detectors.

4. Universality

• Specialized solutions for various applications and modes; EEG (electroencephalogram), VR (virtual reality), TMS (transcranial magnetic stimulation), MRI (magnetic resonance imaging), etc.

• Lightweight and compact appearance, weighing approximately 900 grams.

• Wireless connection and onboard storage enable unrestricted recording.

• NIRSport2 was designed as a research platform from the beginning, taking into account both movement and activity states. Provided an integrated solution. Its compact size (162 mm x 125 mm x 60 mm) and weight of only 900 grams provide significant versatility in motion based applications. In addition, fixed and integrated solutions are provided for applications involving other modes such as EEG, VR, and MRI *.

5. Functions and software

1) Aurora fNIRS acquisition software

• NIRSport2 is equipped with Aurora fNIRS software: improving user friendliness, flexibility, and intuitive workflows.

• Aurora fNIRS only requires a few clicks to set up the complete experimental setup. The automatic signal optimization algorithm ensures optimal signal quality before the measurement begins. After starting to record data, the concentration changes of HbO and Hb can be visualized in real-time in multiple display modes. In addition, there is an immediately available full head visualization feature.

• Aurora fNIRS is developed specifically for NIRx NIRS port2.2) Turbo Satori real-time fNIRS analysis software

• The NIRSport2 platform is integrated with Turbo Satori for real-time online analysis in neurofeedback and BCI (Brain Computer Interface) applications.

3) Satori - * easy-to-use fNIRS analysis software

• Satori natively reads data recorded by NIRSport2 and Aurora. Satori includes the current standard fNIRS processing methods and statistical tools.

4) NIRSport2 Expansion Module

Using NIRxWINGS for synchronous physiological measurements

• The NIRxWINGS module for peripheral physiological measurements extends the functionality of NIRSport2. You can collect blood oxygen saturation (PPG), heart rate variability (HRV), oxygen saturation (SpO2), respiration, temperature, skin electrical response (GSR), and bipolar signals (such as EMG and ECG). All signals are synchronized and in one data stream.

NIRxBorealis: Converting fMRI to fNIRS

• NIRxBorealis can couple up to two NIRSport2 devices with fiber optic guides for fNIRS data acquisition in MRI environments. The main advantage of this system is its flexibility, allowing for mobile and MRI integrated experiments to be conducted using the same NIRSport2 platform. NIRxBorealis also provides low profile fiber optic capability for transcranial magnetic stimulation (TMS)
