[Dynamic EEG mapping--an imaging procedure for studying perceptive, motor and cognitive brain performance].

The spatial pattern and time course of cortical activation can be studied when the event-related desynchronization in 30 EEG recordings is being quantified, averaged over about 60 events and displayed in form of maps with integration times of 125 ms (8 maps/s). This method was named dynamic mapping and used for investigating cortical activation pattern during the following tasks: Planning and execution of voluntary self-paced thumb movements, tactile stimulation of the foot sole and recognition of words, displayed shortly on a computer terminal. All these experiments resulted in localized activation pattern.
