EEG & dry electrodes

Dry electrodes are very popular amongst neuro-gadgets. In this clip we gutted a Mindflex which uses dry electrodes and connected them to our bio-amplifier. Initially, the signal quality was so poor that only 50Hz mains could be seen but then it improved over a period of 10mins which finally allowed displaying the EEG mixed with the artefacts which we would expect: EOG, EMG and cable movements.

After having watched this clip check out this Playlist with examples of EEG mind control and make up your mind if it has been EEG or just artefacts.
