However, neuroscientific findings on the underlying neural substrates of the affect appear to be inconclusive with some reporting the presence of distinct and independent brain systems and others identifying flexible and distributed brain regions. A common theme among these studies is the focus on the change in brain activation. As a result, they do not take into account the findings that indicate the brain activation and its information content does not necessarily modulate and that the stimuli with equivalent sensory and behavioural processing demands may not necessarily result in differential brain activation. In this article, we take a different stance on the analysis of the differential effect of the negative, neutral and positive affect on the brain functioning in which we look into the whole-brain variability: that is the change in the brain information processing measured in multiple distributed regions. For this purpose, we compute the entropy of individuals\u2019 muti-channel EEG recordings who watched movie clips with differing affect. Our results suggest that the whole-brain variability significantly differentiates between the negative, neutral and positive affect. They also indicate that although some brain regions contribute more to such differences, it is the whole-brain variational pattern that results in their significantly above chance level prediction. These results imply that although the underlying brain substrates for negative, neutral and positive affect exhibit quantitatively differing degrees of variability, their differences are rather subtly encoded in the whole-brain variational patterns that are distributed across its entire activity.<\/jats:p>","DOI":"10.3390\/e21121228","type":"journal-article","created":{"date-parts":[[2019,12,17]],"date-time":"2019-12-17T02:59:01Z","timestamp":1576551541000},"page":"1228","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Entropy of the Multi-Channel EEG Recordings Identifies the Distributed Signatures of Negative, Neutral and Positive Affect in Whole-Brain Variability"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0854-0354","authenticated-orcid":false,"given":"Soheil","family":"Keshmiri","sequence":"first","affiliation":[{"name":"Advanced Telecommunications Research Institute International (ATR), Kyoto 619-0237, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Shiomi","sequence":"additional","affiliation":[{"name":"Advanced Telecommunications Research Institute International (ATR), Kyoto 619-0237, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Ishiguro","sequence":"additional","affiliation":[{"name":"Advanced Telecommunications Research Institute International (ATR), Kyoto 619-0237, Japan"},{"name":"Graduate School of Engineering Science, Osaka University, Osaka 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2425","DOI":"10.1126\/science.1063736","article-title":"Distributed and overlapping representations of faces and objects in ventral temporal cortex","volume":"293","author":"Haxby","year":"2001","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"261","DOI":"10.1016\/S1053-8119(03)00049-1","article-title":"fMRI Brain Reading: Detecting and classifying distributed patterns of fMRI activity in human visual cortex","volume":"19","author":"Cox","year":"2003","journal-title":"NeuroImage"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1023\/B:MACH.0000035475.85309.1b","article-title":"Learning to decode cognitive states from brain images","volume":"57","author":"Mitchell","year":"2004","journal-title":"Mach.
