We employ a method to measure the coupling strength between gamma signals (40\u2013100\u2009Hz) on a short time scale as the maximum cross-correlation over a range of time lags within a sliding variable-width window. Instances of coupling states among several signals are also identified, using a mixed multivariate beta distribution to model coupling strength across multiple gamma signals with reference to a common base signal. We first apply our variable-window method to simulated signals and compare its performance to a fixed-window approach. We then focus on gamma signals recorded in two regions of the rat hippocampus. Our results indicate that this may be a useful method for mapping coupling patterns among signals in EEG datasets.<\/jats:p>","DOI":"10.1155\/2010\/946089","type":"journal-article","created":{"date-parts":[[2010,7,29]],"date-time":"2010-07-29T21:37:56Z","timestamp":1280439476000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Coupling among Electroencephalogram Gamma Signals on a Short Time Scale"],"prefix":"10.1155","volume":"2010","author":[{"given":"Michael P.","family":"McAssey","sequence":"first","affiliation":[{"name":"Department of Statistics, University of California Davis, MSB 4118 One Shields Avenue, Davis, CA 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fushing","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Department of Statistics, University of California Davis, MSB 4118 One Shields Avenue, Davis, CA 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne C.","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, University of California TB-170, One Shields Avenue, Davis, CA 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"2006","key":"1"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0701826104"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.79.061916"},{"year":"2006","key":"4"},{"year":"2008","key":"6"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.81.3291"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0193(1999)8:4<194::AID-HBM4>3.0.CO;2-C"},{"issue":"3","key":"9","doi-asserted-by":"crossref","first-page":"424","DOI":"10.2307\/1912791","volume":"37","year":"1969","journal-title":"Econometrica"},{"first-page":"509","volume-title":"Spectral regression|amount of information analysis of seizures in humans","year":"1976","key":"10"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2007.06.003"},{"key":"12","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1111\/j.2517-6161.1977.tb01600.x","volume":"39","year":"1977","journal-title":"Journal of the Royal Statistical Society: Series A"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.eplepsyres.2008.02.002"},{"year":"2009","key":"14"},{"key":"15","doi-asserted-by":"crossref","first-page":"100","DOI":"10.2307\/2346830","volume":"28","year":"1979","journal-title":"Applied Statistics"},{"issue":"8","key":"16","doi-asserted-by":"crossref","first-page":"578","DOI":"10.1093\/comjnl\/41.8.578","volume":"41","year":"1998","journal-title":"The Computer Journal"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-7152(03)00048-8"}],"container-title":["Computational Intelligence and Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2010\/946089.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2010\/946089.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2010\/946089.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,2,23]],"date-time":"2025-02-23T16:05:01Z","timestamp":1740326701000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cin\/2010\/946089\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":16,"alternative-id":["946089","946089"],"URL":"https:\/\/doi.org\/10.1155\/2010\/946089","relation":{},"ISSN":["1687-5265","1687-5273"],"issn-type":[{"type":"print","value":"1687-5265"},{"type":"electronic","value":"1687-5273"}],"subject":[],"published":{"date-parts":[[2010]]}}}
