NeuroSky MindWave - Brainwave test #5

This is the fifth in a series of tests using the NeuroSky MindWave headset, their ThinkGear software, and my own custom software to record brainwaves over time, and graph them. I intentionally tried to focus/concentrate very hard at the beginning of this test, and then transitioned into meditation. I continued to meditate throughout the session, but according to their software/hardware, I tailed off at the end. In my opinion, this is a problem with their hardware -- it becomes less accurate as you use the system longer.

According to their measurements, meditation seems to be the absence of Delta and Theta waves.
