I am getting a (intermittent) signature pattern. The montage can be viewed here.
The effect works synchronously with a slight head movement. When the head rolling movement stops the signature pattern directly reverts to a more normal pattern and this then immediately continues with the same signature pattern when the same head movement resumes. I have tried this several times and found that it affects different sensors and presents different signatures. However, there is always this same correlation. The best way I can describe this phenomena at the moment is ‘sticky’ capacitance that presents a digital relativity that the headset can pick-up for subtle changes in voltage (presuming that a slight charge can be held to an anchor point such as the electric field of the device itself - possibly it’s battery discharge).
Can anyone shed any light on why the EEG headset is picking up gyroscopic movement? Is this a normal phenomena on other sets?
