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

Figure 4

Brain activity related to the observation of the PSA when compared to that of the documentary. The brain is viewed from a frontal view. The color map is relative to the -score values of the power spectra EEG activity during the PSA when compared to the documentary. -score values different from the blue means significant statistically activity. It is possible to note that in the theta frequency band, the right prefrontal cortex is activated while in the beta and gamma frequency bands the activation is rather symmetrical.
