Patients’ pain level of the patients is a fundamental factor for the patients’ anesthetics usage. To investigate the responses of electroencephalogram (EEG) to cold pressor pain in the frequency domain, twenty healthy subjects’ EEG signals were recorded during a cold pressor test. A band-pass filter and independent component analysis were used to preprocess the EEG signal. Fast Fourier transformation as used to analyze the EEG power spectrum. Paired t-tests were performed on the EEG power to investigate the significance of the difference between pain and no-pain EEG power. In pain state, the EEG power increased significantly at EEG channel location Cz, O1, and O2 over most frequency bands: 1–4 Hz, 4–8 Hz, 8–13 Hz, 13–30 Hz, 30–50 Hz. The EEG power of the gamma band increased over extensive brain regions in pain condition. This study suggests that the power of EEG data in pain state has a higher value over most frequency bands. The central and occipital brain regions show the most significant differences between no-pain and pain state. The findings of this study provide evidence that EEG is a promising tool to objectively assess the pain level of human beings.
