Abstract Objective To explore the effect difference of mind-keeping on event-related potential mismatch negative wave (MMN). Methods In March 2019, 72 college students from Dongfang College of Beijing University of Chinese Medicine were recruited and divided into experience group (group A, n = 36) and non-experience group (group B, n = 36) according to whether they had experience or not. EEG was monitored by using event-related potential technology. The latency and peak value of MMN among different states were compared between two groups. Results In group A, the MMN latencies of MK in frontotemporal junction, anterior temporal region, frontal central junction, central region and parietal region were shorter than those of N1 (P < 0.05). In group A, the MMN latencies of N2 in frontal polar region, middle temporal region, frontal central junction area and central region were shorter than those of N1 (P < 0.05). In group B, the MMN latency of MK was shorter than that of N1 in frontotemporal junction (P < 0.05). There was no significant difference in MMN latency among different states between two groups (P > 0.05). In group A, the MMN peak value of MK in frontal region, anterior temporal area, frontal central junction area and central region was decreased compared with N1 (P < 0.05). In group A, the MMN peak of N2 in anterior temporal region was lower than that of N1 (P < 0.05). There was no significant difference in the peak value of MMN among different states in group B (P > 0.05). There was no significant difference in the peak value of MMN among different states between two groups (P > 0.05). Conclusion Mind-keeping can shorten the time for processing external information and improve the efficiency of the brain′s automatic processing.
