Frequency Bands

This demonstrates how one could implement a simple neurofeedback application.

Setting up

With fake or recorded data (no device)

The default configuration uses real recorded data. You can also try sinusoidal waves by commenting out the replay.yaml graph in main.yaml and uncomment sinus.yaml.

Using a BITalino device

Uncomment the bitalino.yaml graph in main.yaml file, and comment out the default replay.yaml graph.

You then need to plug the EEG sensor in input A1, and position the electrodes as follows:

Running the demo

Launch the app:

$ timeflux -d neurofeedback/bands/main.yaml

Open a browser, and visualize:

• The raw EEG data
• The relative and absolute frequency bands for the Fpz channel
