DSI-Hybrid-EEG+fNIR

Dry + Synchronized + Mobile 

The DSI-Hybrid EEG + fNIR headset is a complete, research-grade, combined wireless EEG and fNIR system designed for synchronized recording of the brain’s electrical activity and its hemodynamic response or blood-oxygen-level dependent (BOLD) response. The EEG and fNIR sensors are arranged to allow simultaneous and superimposed recordings at locations distributed on the scalp.

  • Active dry electrode EEG sensor with 2 stage amplification and digitization in headset delivers research-grade EEG signal (>90% correlation with conventional wet electrode systems)
  • Triple frequency ultra-bright LED emitters and amplified detectors offer reliable through hair fNIR
  • fNIR optodes arranged around dry electrode EEG sensors for co-registered measurement of EEG and BOLD
  • Patented artifact resistant electro-mechanical designs enable ambulation in naturalistic environments
  • Short- and Long- light paths fNIR measurements empower integrated algorithms for regression of Mayer wave artifact

Product Features

Description

Practical EEG and fNIR

  • Fully integrated and synchronized, complete EEG and fNIR system in a single device
  • Ideal for combined hemodynamic and electrophysiological research
  • Autodetection of optimal emitters and detectors to use for each fNIR location
  • Raw fNIR signals converted to changes in concentration of oxygenated and deoygenated hemoglobin (BOLD)
  • Rapid set-up and clean-up time
  • Adjustable to fit a wide range of head sizes (52-62 cm)

Powerful Options

  • 8 channel locations with combined EEG and fNIR for concomittant measurement of EEG and fNIR
  • Provides excellent temporal precision from EEG combined with spatial precision from fNIR.
  • Wireless triggering for synchronization of multiple devices (hyper-scanning) and ambulatory ERPs
  • Bluetooth or wired-USB transmission
  • Adjustable power settings for each emitter LED wavelength
