Abstract

An event related potentials (ERPs) imaging system was developed for brain research. The system consists of a personal computer based 19 channel EEG recorder, a visual stimulator, an auditory stimulator and a somatosensory stimulator. The response time can be also measured simultaneously. The EEG decoder starts to accumulate the brain potential signals at 100 ms before the stimulation. The accumulated signals which correspond to ERPs can be displayed in two dimensional distribution which is useful to estimate the position information of activation. Using the developed ERPs imaging system, temporal information as well as position information can be obtained. We conclude that the ERPs imaging system is useful for brain research
