The NIRSport 2 is the most versatile portable commercially-available fNIRS solution available.
Measure fNIRS in high-density set-ups, from anywhere on the head, concurrently with (nearly) any other modality. Monitor your subjects via Wi-Fi while direct-to-device system recording ensures data is always stored, or choose higher-bandwidth USB connectivity for applications in BCI and neurofeedback research paradigms that require ultra-high performance processing.
NIRSport 2 integrates seamlessly with EEG, fMRI, eye-tracking, cochlear implants, TMS, tDCS, EMG, pulse oximetry, and other modalities.
Application-Specific Probes & Headgear
Specialized probes and headgear available for comfortable measurements on any subject, for any application.
User-Friendly, Modular, Scientifically Supported
The NIRSport 2 is a user-friendly, modular, and robust functional near-infrared spectroscopy (fNIRS) platform which measures hemodynamic responses to neuroactivation via oxy-, deoxy-, and total hemoglobin changes in the cerebral cortex.
The NIRSport 2 comes with a host of ready-to-implement upgrades and modules to meet the needs of a broad range of cognitive neuroscience applications.
Our Most Versatile Portable NIRS Solution
Optimize your NIRport 2 system with the precise configuration for your research.
Single System Source numbers:
from 8-64 (8-source increments)
Laser (2- or 4-wavelength; requires NIRScout extension) or LED (2-wavelength)
from 4-32 (4-detector increments)
SiPD (active or fiber optic) APD (active or fiber optic)
Dual-Tandem (2-system), Tri-Tandem (3-system), Quad-Tandem (4-system)
NIRSport 2 Tandem Options
The NIRSport 2 may be ‘daisy chained’ to connect multiple systems together in tandem configuration. 2, 3 or 4 systems may interconnect in tandem mode; in each case, all data and event trigger information is fully-synchronized between NIRSport 2 devices.
For example, in a dual-tandem configuration, detectors from system 1 are reading light from sources in both system 1 and system 2. Likewise, detectors from system 2 are reading light from sources in both system 1 and system 2 as well. This allows research teams to easily expand their studies by combining NIRSport 2 instruments to measure either:
larger brain regions of interest
hyperscanning (multi-subject) fNIRS measurements

NIRSport 2 - The Ideal portable NIRS System for Concurrent NIRS/EEG
Freely-configurable probe arrays easily integrate with EEG and tDCS within a single NIRx NIRScap.
Right: NIRScap integration with passive EEG electrodes and NIRScout NIRS 'optodes' (i.e., NIRS source and detector probes).
NIRx can easily integrate with nearly any EEG electrode for concurrent NIRS/EEG measurements. Integration with passive unshielded, passive shielded, active, and sponge electrode solutions all exist for NIRSport 2 and NIRScap.
Example of NIRSport 2 + EEG Data Integration
Data integration with NIRScout and EEG systems is easy with event synchronization. This may be done at the start and end of experiments, during 'trigger' events, or arbitrarily during the experiment.
Example Right: The event trigger generated by the presentation computer is sent to the digital interface (trigger splitter), where the events are then sent to the NIRx trigger splitter box, splitting each trigger and maintaining the proper voltage, sending the even signal to the NIRS and EEG systems. This trigger-splitting method may be used from different input devices (e.g., TMS, eye-tracking, etc.), and sent to multiple recording devices.

Real-Time Processing of fNIRS Data
Many NIRScout end-users process their NIRScout data in real-time for brain-computer interface (BCI) and neurofeedback applications.
The diagram below is an abstraction of both neurofeedback and BCI data flow.
1) Physiological data are collected from a subject (e.g., fNIRS, EEG, fMRI, EKG, etc.)
2) Feature extraction and classification are used to characterize the data (with multi-modal considerations, if available and relevant)
3) The subject data is either used for:
a) BCI-based application - controlling a software program, robot, etc.
b) Neurofeedback, influencing the subject, thereby altering the physiological signals (ideally). Feedback are typically visual, audible, or haptic.
