Abstract The aim of this paper is to figure out the most obvious region change of the brain function area for 3DTV by detecting eyeclosed EEG signal’s changes of preand postwatching 3DTV and establish the special method of EEG electrode placement for 3DTV health assessment. Fourty of healthy, age at 21～23 years old male volunteers was selected. The experiment volunteers were divided into two groups to watch the same time 3DTV in a continuous or discontinuous experimental mode. The EEG signal of preand postwatching 3DTV in the whole experimental process was recorded. By contrasting the changes of three bands α, β and θ waves’ relative energy, R value and A/B value of all channels of preand postwatching 3DTV eyeclosed signal and counting the number of the channels with the statistical significance in all the brain regions, the changes in various brain regions was analized. By analyzing α, β, θ wave relative energy, A/B value and R value of the two groups’ EEG signal, in the vision region and its vicinity the channels with the statistical significance were O1, O2, P3 and T6 channels; in the frontal region the channels with the statistical significance were FP2, F3 channels; in the rest of the regions, only the central region channel C4 had statistical significant variation. The most obvious change in every brain region was the vision region followed by the frontal region; the central zone was the slight obvious region.
