Background:

Electroencephalography (EEG) shows promise for emotion recognition.
Multichannel EEG data presents challenges like redundancy and computational complexity.
Efficient single-channel selection is crucial for practical EEG-based emotion recognition.

Purpose of the Study:

To propose a novel method for single-channel selection in EEG-based emotion recognition.
To reduce data redundancy and computational load in emotion recognition systems.
To identify optimal channels and time segments for accurate emotion detection.

Main Methods:

Brain Rhythm Sequencing (BRS) interprets EEG by identifying the dominant brain rhythm at 0.2s intervals.
Dynamic Time Warping (DTW) is employed for classifying rhythm sequences based on similarity.
Single-channel selection is achieved by evaluating channel performance in emotion recognition tasks.

Main Results:

Classification accuracies ranging from 70% to 82% were achieved using single-channel EEG data.
Optimal performance was obtained with a 10-second time length, demonstrating efficiency.
The study identified representative channels and time segments, highlighting individual characteristics.

Conclusions:

BRS offers an effective solution for single-channel selection in emotion recognition.
The method significantly simplifies EEG data processing while maintaining high accuracy.
This approach paves the way for more accessible and practical brain-computer interfaces for emotion analysis.
