| Resumo: | Understanding the processing of emotions has always been a topic of interest, nevertheless, little is known about the temporal and spatial dynamics of early processing of emotions. Whereas recording systems such as “Electroencephalography” (EEG) gives us very good temporal information, - in millisecond range -; other systems such as Functional Magnetic Resonance Imaging (fMRI) are able to give us an excellent spatial resolution. In this document, we propose to combine EEG techniques with fMRI and with mathematical calculations of connectivity between electrode nodes in order to be able to better understand the processing of emotional information and the temporary windows and spatial locations. As an emotion stimulus, we use standardized images obtained from the International Affective Picture System (IAPS) database and distinguish between biphasic (positive and negative) emotions. Results indicate that this system can be of great help to provide Information on neuro-emotional processing. We see the existence of a lateralization in the processing: positive emotions are processed with the left frontal hemisphere whereas the right frontal hemisphere is in charge of the negative ones; In addition, we observe a greater intensity of the negative emotions. On the other hand, with the aim of adding systems that allow us to locate the points of interest of fixation of the look in the processing, studies concerning the following of these looks have been made in other lines of investigation. The complex EEG system has allowed us to carry out valuable scientific research in other areas of knowledge, such as landscape visual impacts and interior design. |
