This paper presents an EEG-based monitoring system designed to evaluate the therapeutic efficacy of acupuncture on human brain activity by extracting periodic and aperiodic features. The system records EEG signals during acupuncture stimulation and analyzes them to assess the modulatory effects of different acupuncture manipulations. Key findings include: 1. **Enhanced Alpha Band Activity**: Acupuncture significantly enhances alpha band (8-12 Hz) activity, particularly in the parietal and occipital lobes, during and after stimulation. 2. **Aperiodic Exponent Reduction**: The aperiodic exponent, which reflects the 1/f-like characteristic of power spectra, decreases during acupuncture, indicating a shift towards higher excitability in the brain. 3. **Sensitivity Index**: A sensitivity index, combining adjusted power and aperiodic exponent, is calculated to quantify the modulatory effect of acupuncture on different brain regions. 4. **Knowledge Graph**: A knowledge graph is established to illustrate the effects of different acupuncture manipulations on brain activity, providing a comprehensive understanding of acupuncture's impact. The system demonstrates the effectiveness of EEG-based measurements in quantitatively evaluating acupuncture's therapeutic effects, offering a new perspective for improving clinical applications in neural disorders.This paper presents an EEG-based monitoring system designed to evaluate the therapeutic efficacy of acupuncture on human brain activity by extracting periodic and aperiodic features.
