Study on the Influence of Positive Emotion on the Recognition Accuracy of Motor Imagery

This paper uses emotional film clips to induce the subjects to produce corresponding emotions. First to do the MI experiment under neutral emotion, then to do the experiment under positive emotion. Therefore, the effect of positive emotion on the recognition accuracy of MI EEG signal is discussed. This paper uses CSP algorithm and FBCSP algorithm to compare and analyze EEG dates. The results show that the positive emotion induced by film clips can improve the accuracy of MI recognition and the degree of improvement varies from person to person. This conclusion can be used in rehabilitation training of stroke patients. If stroke patients are depressed, rehabilitation training can be carried out through active video to induce stroke patients to produce positive emotions, thus improving the effect of rehabilitation training.
