Background:

Recognizing human emotional states via electroencephalography (EEG) is crucial for advancing human-computer interaction.
Music-evoked emotions present a complex challenge for automated analysis due to their nuanced nature.

Purpose of the Study:

To develop an automated system for recognizing music-evoked emotions using region-specific EEG signals and dynamic functional connectivity.
To evaluate the efficacy of a deep learning model (Xception) combined with channel selection for emotion recognition.

Main Methods:

Collected EEG signals from 15 healthy volunteers experiencing high-valence-arousal and low-valence-arousal emotions induced by music.
Employed a sequential backward selection algorithm with the Xception deep neural network to identify optimal channel combinations.
Assessed the impact of dynamic functional networks of the frontal cortex, varying by trial number, on emotion cognition performance.

Main Results:

Achieved 70.19% accuracy using all 30 EEG channels, 71.05% using frontal region channels, and 76.84% using the best frontal channel combination.
Demonstrated that classification performance improved with longer temporal functional networks of the frontal cortex.
Confirmed that emotions induced by music can be recognized using region-specific EEG signals and time-varying frontal cortex functional networks.

Conclusions:

The proposed approach effectively recognizes music-evoked emotions through targeted EEG analysis and dynamic functional connectivity.
Findings offer a novel perspective for developing EEG-based emotion recognition systems and deepen the understanding of neural mechanisms in emotion processing.
