EEG Analysis of the Brain Activity during the Observation of Commercial, Political, or Public Service Announcements
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.
