To quote their PDF "There is also the issue that brain research has advanced but we are not too concerned with the dissection
of the signals into specific origins of neuronal / muscular groups, rather, as mentioned above, it is the
synergism of all physiological activities that is the critical signal we are trying to read and understand to
the point where we can use it."
also "The new headbands we are using embrace sensors based on carbon nanofibers that are about 100 times
more sensitive than older technology. This allows for a much wider dynamic range and also to pick up
signals that were completely masked in previous approaches and that makes the use much more intuitive
