Abstract
This work groups subjects by their duration of experience with meditation, then measures their ECG and EEG during meditation and emotion-stimulating experiments by using IAPS. By analyzing EEG and HRV in the frequency domain we can observe how ANS and brain actions change. This research proposes a method to objectively estimate the meditation performance. In this way, subjects may self-assess their meditation performance. Subjects are sorted by objective meditation performance as well as by subjective meditation experience so as to analyze the effect of meditation in emotion-stimulating experiments.The results show that during meditation, the power of the EEG Alpha wave and the low-frequency component of HRV increases, but the LF/HF ration and high-frequency component of HRV decreases. Compared with the group of people who have no experience with meditation, people who meditate regularly show more improvement in the power of EEG and HRV after meditation. This work demonstrates that meditation will improve the performance of balancing ANS and relaxation as well as steadying brain action. Those who have practiced meditation for a longer period of time will have better performance. During emotional stimulus, people who have inferior performance and less experience with meditation have significant changes in LF/HF ration and the high-frequency component of HRV. Furthermore, the average power of EEG Beta waves (on behalf of the sensory stimulation) is also larger. Thus, the conclusion has been reached that meditation is helpful to reduce the effects of emotional stimulus.
