<u><b><big>Overview</big></b></u>
This scenario can be used in order
to check the quality of the signals
before starting an experiment.
One should <u>definitely</u>
check the quality of the signals
and ensure that :
- <b>eye blinks</b> are visible
- <b>jaw clenching</b> are visible
- <b>alpha waves</b> are visible when closing eyes
