Cortical DC-Shifts Related to Sustained Sensory Stimulation and Motor Activity

On the question of event-related slow (DC) potentials in the brain, Haider et al. (1981) published a review paper some years ago. Since that time our group has tried to deal with brain DC shift related to longer term information processing and motor activity. This is of course only possible with the use of special DC electrodes and special DC amplification systems.
