> After a downwards magnetic field rotated counterclockwise, some people responded with a large drop in amplitude of their EEG alpha waves, up to a 60% decrease from pre-stimulus levels. Alpha waves are EEG oscillations that go up and down at a frequency around 10 Hz (10 times per second). They dominate the EEG signal when we are awake with our eyes closed, and arise from the spontaneous, synchronized activity of millions of neurons. Their function is not well-understood, but they may reflect a relaxed mind with nothing in particular to focus on and no particular task to do. When a stimulus suddenly appears and is processed, neurons fall out of synchrony with each other, the alpha rhythm is disrupted, and alpha waves get smaller as a result.
