By means of pattern recognition algorithms as well as time-variant spectral aridcoherence analysis, a so-called &amp;ldquo;initial wave&amp;rdquo; (narrow band rhythm within a frequency range of 3-12 Hz) can be demonstrated within the first part of the burst pattern. The detection of this signal component and of the quadratic phase coupling is more successful in the frontal region. By means of amplittide demodulation of the &amp;ldquo;initial wave&amp;rdquo; the phase coupling can be attributed to an amplitude modulation. The results were derived from 6 neonates (20 burst patterns for each neonate; 8-channel recordings). A 16-channel EEG-recording was analyzed for one neonate.<\/jats:p>","DOI":"10.3233\/978-1-60750-896-0-1250","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T09:02:47Z","timestamp":1740128567000},"source":"Crossref","is-referenced-by-count":0,"title":["Multimodal Time-variant Signal Analysis of Neonatal EEG Burst Patterns"],"prefix":"10.3233","author":[{"family":"Witte Herbert","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Putsche Peter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Eiselt Michael","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Hoffmann Katrin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Arnold Matthias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"J&auml;ger Heinrich","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Leistritz Lutz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO &amp;apos;98"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T09:26:24Z","timestamp":1740129984000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=52&spage=1250"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-896-0-1250","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[1998]]}}}
