ERP analysis of emotional stimuli from brain EEG signal
نویسندگان
چکیده
The main objective of our study is to analyze the event related potential (ERP) of EEG brain signal from different emotional responses. An affective picture simulation was designed to find out neurophysiological characteristics of EEG brain signal. Event oriented EEG dynamics in ERP were analyzed statistically by using the one-way ANOVA method (p<0.01). Twenty one healthy college students were employed in this experiment. We used the standard IAPS database for picture's simulation. These affective pictures were further classified in four emotional classes. They are happy, calm, sad, and scared. The results shown that, there were the differences of stimulus response at the frontal region of the brain between the 1000ms and 1200ms. However, we also found the early ERP which is P300 at occipital and parietal regions of the brain.

The perceptual processing of emotional stimuli is subject to the regulation of brain function. This study investigated whether frontal electroencephalography (EEG) alpha asymmetry at resting conditions predicted the evaluation of emotional picture stimuli by event-related potentials (ERPs). In this study, participants first completed a 2-min resting task, and then passively viewed emotional pic...
