Following a transformation into the frequency domain, the brain's response is often evident at the frequency of stimulation, F, and its higher harmonics (2F, 3F, etc.). This approach is increasingly used in neuroscience, as it affords objective measures to characterize brain function. However, whether these specific harmonic frequency responses should be combined for analysis\u2014and if so, how\u2014remains an outstanding issue. In most studies, higher harmonic responses have not been described or were described only individually; in other studies, harmonics have been combined with various approaches, for example, averaging and root-mean-square summation. A rationale for these approaches in the context of frequency-based analysis principles and an understanding of how they relate to the brain's response amplitudes in the time domain have been missing. Here, with these elements addressed, the summation of (baseline-corrected) harmonic amplitude is recommended.<\/jats:p>","DOI":"10.1162\/jocn_a_01763","type":"journal-article","created":{"date-parts":[[2021,7,17]],"date-time":"2021-07-17T14:44:53Z","timestamp":1626533093000},"page":"1-22","update-policy":"https:\/\/doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":55,"title":["Harmonic Amplitude Summation for Frequency-tagging Analysis"],"prefix":"10.1162","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6143-0811","authenticated-orcid":true,"given":"Talia L.","family":"Retter","sequence":"first","affiliation":[{"name":"University of Luxembourg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruno","family":"Rossion","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Lorraine, Nancy, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Schiltz","sequence":"additional","affiliation":[{"name":"University of Luxembourg"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","published-online":{"date-parts":[[2021,7,16]]},"container-title":["Journal of Cognitive Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/direct.mit.edu\/jocn\/article-pdf\/doi\/10.1162\/jocn_a_01763\/1929766\/jocn_a_01763.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/direct.mit.edu\/jocn\/article-pdf\/doi\/10.1162\/jocn_a_01763\/1929766\/jocn_a_01763.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,7,17]],"date-time":"2021-07-17T14:44:59Z","timestamp":1626533099000},"score":1,"resource":{"primary":{"URL":"https:\/\/direct.mit.edu\/jocn\/article\/doi\/10.1162\/jocn_a_01763\/102997\/Harmonic-Amplitude-Summation-for-Frequency-tagging"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,7,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1162\/jocn_a_01763","relation":{},"ISSN":["1530-8898"],"issn-type":[{"value":"1530-8898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,7,16]]}}}
