Figure 3: Representation of the filtered GFP related to frontal electrodes in the theta band (left panel) and beta and gamma bands (right panel) for the analyzed population during the observation of a commercial (row a) and a Public Service Announcement (row b) against the smoking. On the -axis, there is the time duration of the spot; on the -axis there is the -score value of the GFP considered. Values greater than 2 mean a difference in power spectral activity during the PSA when compared to those of the documentary that are statistically significant at 5%. The red line is the average -score values of the GFP in blocks of five seconds of spot.
