In this study, International Affective Picture System (IAPS) were used to evoke fear and neutral stimuli using EMOTIV EPOC EEG recognition system (n=15). During the experiments, EEG data were recorded using the Test bench program. To synchronize the EEG records, IAPS pictures were reflected on the screen. A Python script was written in the Open Sesame program to provide a synchronized data flow in the Input/Output channels of the installed virtual serial port. The Event-Related Oscillations (ERO) responses and Event-Related Potentials (ERPs) were calculated. Statistically significant differences (p<0.05) were observed among the mean amplitude differences in the P7, O1, F3, AF3, P8 channels at 200-400 milliseconds in the ERP analysis, and also significant (p<0.05) differences were found in alpha(∝) and beta(β) brainwaves compared to neutral stimuli, in the Fast Fourier Transform (FFT) analysis. After these evaluations, different time-spectral signal activity patterns occurred in the right frontal lobe (F4) at the (∝) band, and in the left parietal lobe at the (β) band, respectively.
