Resumen (en)
Electroencephalography signals (EEG) has captured the general interest of the scientific community; nowadays, the most part of the investigations of the topic are focused on the emotional psychophysiological effect that this kind of signals are able to show according different types of stimuli; therefore, this document shows the analysis of different sets of EEG signals, captured by NeuroSky headset, under the stimulation produced by emotional content sounds from the IADS (International Affective Digital Sounds); furthermore, some EEG signals from the "DREAMER" dataset were also analyzed. From this document was mainly concluded that there was a corresponsive result between subjective and objective data as valence and arousal values were corresponsive with EEG frequency bands; furthermore, for DREAMER set, electrodes of the right hemisphere were the ones with more energy.
Resumen (es)
Las señales de electroencefalografía (EEG) han captado el interés de la comunidad científica; actualmente, la mayoría de las investigaciones están enfocadas a cómo estas señales reflejan la respuesta psicofisiológica de las personas, en términos emocionales, respecto a diferentes estímulos; por esta razón, en este documento se presenta el análisis de señales de EEG captadas por el headset de NeuroSky ante estímulos sonoros con contenido emocional provenientes de la IADS (International Affective Digital Sounds); además, se analizaron algunas señales del dataset de EEG “DREAMER”. De este desarrollo se llegó a que hay una correspondencia entre los valores de Valencia y Arousal con las bandas de frecuencia de EEG, observando además que, para el caso del DREAMER, los electrodos correspondientes al hemisferio derecho presentaban la mayoría de la energía en el cerebro.
