[The significance of slow brain potentials for the estimation of activation processes in activities at the video-screen model workplace].
Numerous studies have shown that the slow potentials registered in the EEG allow conclusions on changes in activation processes preceding different activities. The Bp which has so far been analysed preferably as motoric phenomenon, is in the following used to furnish evidence of activation processes preceding mental performance at a visual display terminal. The analysis reveals the relationships between the Bp and mental load, mental performance, and a varying dynamic activation. From that, conclusions can be drawn already in the phase of preparing different information processing activities on variations in central-nervous activation and most likely even on the readiness to perform and the reliability of actions.
