Evaluation of a Multi-Channel EEG (Electroencephalogram) Measurement Electrode System

摘要

This paper reports on the evaluation of the 42 ch ECI electro-cap system. During P300 experiments, the amount of time the cap was worn and each impedance were measured. After the experiment, participants were interviewed about the cap. The results showed that using this cap enabled us to fix all electrodes to a scalp within 30 minutes, with low impedance. The subjective evaluation results showed that in the two-hour-EEG (Electroencephalogram) measurement most participants felt little pain. This result proves that electro-cap system is useful of multi-channel EEG measurements not only for brain research but also for clinical testing.
