With NIRScout, you can measure fNIRS from anywhere on the head concurrently with (nearly) any other modality. It is our most versatile solution for fNIRS researchers.
NIRScout is ideal for multi-modal measurements with EEG, fMRI, eye-tracking, cochlear implants, TMS, tDCS, EMG, pulse oximetry, and other modalities for concurrent measurements.
Application-Specific Probes & Headgear
Specialized probes and headgear available for comfortable
measurements on any subject, for any application.
User-Friendly, Modular, Scientifically Supported
The NIRScout 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 NIRScout platform includes a host of ready-to-implement upgrades and modules to meet the needs of a broad range of cognitive neuroscience applications.
fNIRS that is Easy to Learn and Use
Connection to the NIRScout systems is quick and easy, with 'thumbscrew-style' probe connectors (shown right).

NIRScout - The Ideal 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 NIRScout and NIRScap.
Example of NIRScout + 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.
Other NIRScout Advantages
