Table 2 Key electrodes selection and their functional roles in emotion recognition.
From: Video-dominant emotion recognition for portable EEG-based devices
Brain region | Selected electrodes | Primary functions in emotion recognition |
|---|---|---|
Prefrontal cortex | FP1, FP2, F3, F4 | Emotional regulation, valence assessment, executive control, and affective decision-making processes |
Central cortex | C3, C4 | Discrimination of high and low arousal states, sensorimotor integration, and detection of physiological activation |
Temporal cortex | T7, T8 | Auditory emotional processing, emotional memory encoding, and interactions with amygdala regions |
Parietal cortex | Pz | Attentional modulation during emotional stimuli processing and suppression of ocular artifacts |
Occipital cortex | O1, O2 | Visual processing of emotional stimuli and distinction of emotionally salient visual content |
