Previously, ErrP-related research usually focused on the design of automatic correction and the error correction mechanisms of high-risk pipeline-type judgment systems. Mounting evidence suggests that the cerebellum plays an important role in various cognitive processes. Thus, this study introduced cerebellar information to enhance the online classification effect of error-related potentials. We introduced cerebellar regional characteristics and improved discriminative canonical pattern matching (DCPM) in terms of data training and model building. In addition, this study focused on the application value and significance of cerebellar error-related potential characterization in the selection of excellent ErrP-BCI subjects (brain\u2013computer interface). Here, we studied a specific ErrP, the so-called feedback ErrP. Thirty participants participated in this study. The comparative experiments showed that the improved DCPM classification algorithm proposed in this paper improved the balance accuracy by approximately 5\u201310% compared with the original algorithm. In addition, a correlation analysis was conducted between the error-related potential indicators of each brain region and the classification effect of feedback ErrP-BCI data, and the Fisher coefficient of the cerebellar region was determined as the quantitative screening index of the subjects. The screened subjects were superior to other subjects in the performance of the classification algorithm, and the performance of the classification algorithm was improved by up to 10%.<\/jats:p>","DOI":"10.3390\/brainsci14030214","type":"journal-article","created":{"date-parts":[[2024,2,26]],"date-time":"2024-02-26T06:50:23Z","timestamp":1708930223000},"page":"214","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Identification and Verification of Error-Related Potentials Based on Cerebellar Targets"],"prefix":"10.3390","volume":"14","author":[{"given":"Chang","family":"Niu","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Xidian University, Xi\u2019an 710126, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuang","family":"Yan","sequence":"additional","affiliation":[{"name":"Nanjing Research Institute of Electronic Technology, Nanjing 210019, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kuiying","family":"Yin","sequence":"additional","affiliation":[{"name":"Nanjing Research Institute of Electronic Technology, Nanjing 210019, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shenghua","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Xidian University, Xi\u2019an 710126, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"561","DOI":"10.1093\/brain\/121.4.561","article-title":"The cerebellar cognitive affective syndrome","volume":"121","author":"Schmahmann","year":"1998","journal-title":"Brain J.
