The EEG system is integrated into the Flow device and the electrical signals are digitized and streamed together with the optical data over the single USB-C port. We handle all synchronization between the TD-fNIRS and EEG data at the hardware level before it leaves the headset.
The details of this system are:
- 6 active dry electrodes that are integrated into the helmet and are placed close to OZ, PZ, CZ, FZ, F3, and F4 on the 10-10 grid. Ground and Reference electrodes are included.
- Sampling rate up to 1kHz per channel
- Impedance and electrical signals are reported for each of the active channels.
