Brainwaves and Bruce Cathie. Brainwave entrainment sound files.

We did an EEG at the hospital which is very similar to this. And they required us to hyperventilate; breath fast for 5-10 minutes before the test, and this possibly improves the reaction time of the brain, though there was no negative ionizer ("sufstoff" machine) at the hospital. Look up negative (oxygen) ions.
