    Area of Science:

    • Neuroscience
    • Cognitive Neuroscience
    • Brain Imaging

    Background:

    • Facial stimulation elicits event-related potential (ERP) component N170 in the fusiform gyrus.
    • The fusiform gyrus's role in facial preference remains unclear.
    • Current facial preference research primarily uses scalp-domain electroencephalography (EEG) signals.

    Purpose of the Study:

    • To investigate the involvement of the fusiform gyrus in processing facial preference emotions.
    • To analyze energy distribution in the source domain of EEG signals during facial preference tasks.
    • To clarify the specific sub-regions of the fusiform gyrus engaged in facial preference.

    Main Methods:

    • Utilized EEG signal analysis focusing on source domain energy distribution.
    • Examined event-related potentials (ERPs) related to facial preference.
    • Compared energy distribution patterns between left and right hemispheres.

    Main Results:

    • The pars orbitalis cortex within the fusiform gyrus showed the highest energetic activity during facial preference tasks.
    • Significant differences in energy distribution were observed between the left and right hemispheres.
    • Source domain analysis provided insights beyond traditional scalp-domain EEG.

    Conclusions:

    • The pars orbitalis cortex plays a crucial role in processing facial preferences.
    • Hemispheric lateralization is evident in the neural processing of facial preference.
    • Findings suggest potential clinical applications for assessing pars orbitalis function in facial recognition disorders.
