Similar changes in those with a history of mTBI (i.e. concussion), however, have not been consistently reported. Frontal theta-to-gamma frequency ratio has shown promise in EEG research in predicting performance on working memory tasks. In the present study we explored the sensitivity of the frontal theta-to-gamma relative power spectral density (PSD) ratio to the history of concussion in 81 youth athletes (18 with a history of concussion, ages 13\u201318) during the tests of the Nike Sensory Training Station that vary in working memory and processing speed demands and motor output requirements. The results showed that the theta-to-gamma relative PSD ratio was significantly lower in the concussion history group on the tests of target capture, perception span and hand reaction time. A principle component analysis further indicated that this metric reflects an underlying dimension shared by several visuo-motor control tests of the Nike battery. The results suggested persistent deficits in psychomotor ability in the athletes with a history of concussion that may have implications for diagnosis, rehabilitation and athletic training.<\/jats:p>","DOI":"10.1038\/s41598-019-54054-9","type":"journal-article","created":{"date-parts":[[2019,11,26]],"date-time":"2019-11-26T11:02:41Z","timestamp":1574766161000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Frontal theta-gamma ratio is a sensitive index of concussion history in athletes on tasks of visuo-motor control"],"prefix":"10.1038","volume":"9","author":[{"given":"Dmitri","family":"Poltavski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyle","family":"Bernhardt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Mark","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8915-6375","authenticated-orcid":false,"given":"David","family":"Biberdorf","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2019,11,26]]},"reference":[{"key":"54054_CR1","doi-asserted-by":"publisher","first-page":"375","DOI":"10.1097\/00001199-200609000-00001","volume":"21","author":"JA Langlois","year":"2006","unstructured":"Langlois, J.
