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

<table>Brain activity related to the observation of the PSA when compared to that of the documentary. The brain is viewed from a frontal view.

</svg>-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.</table>
