The neuronal dynamic was characterized using mathematical tools defined in different frameworks (rate, oscillations or complex patterns). Then, and for each cortical area, multivariate and discriminate analyses were further performed on these features to identify those important to differentiate between the normal and the pathological neuronal activity. Our results show a different order in the importance of the features to discriminate the pathological state in each cortical area which suggests that the M1 and the SMA exhibit dissimilarities in their neuronal alterations induced by parkinsonism. Our findings highlight the need for multiple mathematical frameworks to best characterize the pathological neuronal activity related to parkinsonism. Future translational studies are warranted to investigate the causal relationships between cortical region-specificities, dominant pathological hallmarks and symptoms. <\/jats:p>","DOI":"10.1142\/s0129065720500100","type":"journal-article","created":{"date-parts":[[2020,1,8]],"date-time":"2020-01-08T03:16:32Z","timestamp":1578453392000},"page":"2050010","source":"Crossref","is-referenced-by-count":5,"title":["Parkinsonism Differently Affects the Single Neuronal Activity in the Primary and Supplementary Motor Areas in Monkeys: An Investigation in Linear and Nonlinear Domains"],"prefix":"10.1142","volume":"30","author":[{"given":"Olivier","family":"Darbin","sequence":"first","affiliation":[{"name":"Department of Neurology, University South Alabama, 307 University Blvd, Mobile, AL 36688, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhiko","family":"Hatanaka","sequence":"additional","affiliation":[{"name":"Division of System Neurophysiology, National Institute for Physiological Sciences and Department of Physiological Sciences, SOKENDAI (Graduate University for Advanced Studies), Okazaki, Aichi 444-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sayuki","family":"Takara","sequence":"additional","affiliation":[{"name":"Division of System Neurophysiology, National Institute for Physiological Sciences and Department of Physiological Sciences, SOKENDAI (Graduate University for Advanced Studies), Okazaki, Aichi 444-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuya","family":"Kaneko","sequence":"additional","affiliation":[{"name":"Division of System Neurophysiology, National Institute for Physiological Sciences and Department of Physiological Sciences, SOKENDAI (Graduate University for Advanced Studies), Okazaki, Aichi 444-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satomi","family":"Chiken","sequence":"additional","affiliation":[{"name":"Division of System Neurophysiology, National Institute for Physiological Sciences and Department of Physiological Sciences, SOKENDAI (Graduate University for Advanced Studies), Okazaki, Aichi 444-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dean","family":"Naritoku","sequence":"additional","affiliation":[{"name":"Department of Neurology, University South Alabama, 307 University Blvd, Mobile, AL 36688, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Martino","sequence":"additional","affiliation":[{"name":"Department of Neurology, University South Alabama, 307 University Blvd, Mobile, AL 36688, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Nambu","sequence":"additional","affiliation":[{"name":"Division of System Neurophysiology, National Institute for Physiological Sciences and Department of Physiological Sciences, SOKENDAI (Graduate University for Advanced Studies), Okazaki, Aichi 444-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,2,5]]},"reference":[{"key":"S0129065720500100BIB001","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.16-20-06513.1996"},{"key":"S0129065720500100BIB002","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2007.11.040"},{"key":"S0129065720500100BIB003","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.19-09-03527.1999"},{"key":"S0129065720500100BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/S0926-6410(00)00028-8"},{"key":"S0129065720500100BIB005","first-page":"208","volume":"111","author":"Fourment A.","year":"1997","journal-title":"Exp.
