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
