Exploration of the dynamics of brain activity in the conditions of executive control by means of the EEG method under using of the DLP and 3LCD projectors
The DLP and 3LCD projectors differ in the presentation techniques of color images. It is possible to suggest that the brain activity related on visual images recognition depends on the kind of projectors chosen for the image presentation. In this study, the patterns of human brain activity recorded during execution of stop-signal paradigm were analyzed for comparison of effects of the DLP and 3LCD projectors on human perception. The significant differences between the effects of projectors were obtained in the delta and theta frequency bands (1-8 Hz). In our interpretation, the application of the 3LCD projector demands the smaller tension of visual cortex and induces smaller brain exhaustion, than it is observed during using the DLP projector.
