NIRScout Advantages
The NIRScout is user-friendly, modular, and a 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.
NIRScout (NSC) Advantages:
- Ability to measure both topographic and tomographic measurements, can freely place probes anywhere on the cortex.
- Modular design allows for easy and efficient upgrades and increased coverage, when needed.
- Hyperscanning: single system can synchronously collect measurements from multiple participants simultaneously.
- Illumination pattern (source firing sequence) fully customizable, which increases sampling rate, and prevents crosstalk.
- Up to 255 triggers input, and up to 255 triggers output.
NIRScout Extended Plus (NSXP) Advantages:
- Can be configured to use laser sources, LED sources, or both, depending on your research needs.
- Fiber based system allows for safe data collection within MR.
- Ability to use 4-wavelength and 8-wavelength sources. Used for detecting additional chromophores beyond hemoglobin (i.e. Cytochrome c oxidase).
- Flat fibers and optodes allow for data collection for concurrent TMS and fNIRS applications.
- Has expanded coverage, beyond our standard NIRScout system.
Functionality
The NIRScout is our most versatile lab based system.
Set up fNIRS Fast
NIRx uses the NIRScap and proprietary signal optimization procedure for an incredibly fast setup (see video of <60-second setup).
High data quality
Sampling rate of 100Hz, sensitivity of SiPD: < 1 pW or APD: 0.5pW, with a high dynamic range of 90 dBopt.
Multi-Modal Integration
NIRScout is ideal for multi-modal measurements with EEG, fMRI, eye-tracking, cochlear implants, TMS, tDCS, EMG, and other modalities for concurrent measurements.
