Visualization of gender differences under different emotional states is performed in this article. Accomplished by Electroencephalographic (EEG) based functional connectivity patterns. Eighteen young participants view advertisement film clips in series that evoked the following emotional states: neutral, positive, or negative. A wireless EMOTIV EPOC EEG headset with 14 channels has used to collect EEG signals from subjects who shown a series of advertisement clips. Coherence is used as a connectivity index to estimate the functional brain connectivity on EEG signals. Brain connectivity is analyzed on alpha, beta, and theta frequency bands for all the three emotions. Results indicate that while viewing the negative advertisements right hemispheric activation is greater in men while women have left hemispheric activation. The right hemisphere is activated in men more than in women. So the left hemisphere finds more active during the advertisement perceive by women, as positive and more right hemisphere activation is found during the advertisement perceive as negative by men. Also, men show strong connectivity in the frontal region while women show activation in all parts of the brain during different emotions. Emotion processing shows characteristics of small-world networks. Having high clustering coefficients and short path length in brain networks which reveals that men positive and neutral emotions are affected by small-world properties of functional connectivity networks. However, women rivalry attributes are found in all the three categories of emotions.
