While providing detailed information about the state of a specific muscle, this technique has limitations such as the need for a priori assumptions about electrode placement and difficulty with recording muscular activity patterns from extended body areas at once. For head and face muscle activity, the present work aimed to overcome these restrictions by exploiting magnetoencephalography (MEG) as a whole head myographic recorder (head magnetomyography, hMMG). This is in contrast to common MEG studies, which treat muscular activity as artifact in electromagnetic brain activity. In a first proof\u2010of\u2010concept step, participants imitated emotional facial expressions performed by a model. Exploiting source projection algorithms, we were able to reconstruct muscular activity, showing spatial activation patterns in accord with the hypothesized muscular contractions. Going one step further, participants passively observed affective pictures with negative, neutral, or positive valence. Applying multivariate pattern analysis to the reconstructed hMMG signal, we were able to decode above chance the valence category of the presented pictures. Underlining the potential of hMMG, a searchlight analysis revealed that generally neglected neck muscles exhibit information on stimulus valence. Results confirm the utility of hMMG as a whole head electromyographic recorder to quantify muscular activation patterns including muscular regions that are typically not recorded with EMG. This key advantage beyond conventional EMG has substantial scientific and clinical potential.<\/jats:p>","DOI":"10.1111\/psyp.13507","type":"journal-article","created":{"date-parts":[[2019,11,25]],"date-time":"2019-11-25T06:29:01Z","timestamp":1574663341000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Head magnetomyography (hMMG): A novel approach to monitor face and whole head muscular activity"],"prefix":"10.1111","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8936-4171","authenticated-orcid":false,"given":"Guido","family":"Barchiesi","sequence":"first","affiliation":[{"name":"Centre for Cognitive Neuroscience and Department of Psychology University of Salzburg Salzburg Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gianpaolo","family":"Demarchi","sequence":"additional","affiliation":[{"name":"Centre for Cognitive Neuroscience and Department of Psychology University of Salzburg Salzburg Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank H.","family":"Wilhelm","sequence":"additional","affiliation":[{"name":"Division of Clinical Psychology, Psychotherapy, and Health Psychology Department of Psychology University of Salzburg Salzburg Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne","family":"Hauswald","sequence":"additional","affiliation":[{"name":"Centre for Cognitive Neuroscience and Department of Psychology University of Salzburg Salzburg Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ga\u00ebtan","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Lyon Neuroscience Research Center Brain Dynamics and Cognition Team INSERM UMRS 1028 CNRS UMR 5292 Universit\u00e9 Claude Bernard Lyon 1 Universit\u00e9 de Lyon Lyon France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nathan","family":"Weisz","sequence":"additional","affiliation":[{"name":"Centre for Cognitive Neuroscience and Department of Psychology University of Salzburg Salzburg Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,11,25]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-88-470-2463-2"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2010.06.020"},{"key":"e_1_2_6_4_1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1093\/oso\/9780195169157.003.0003","volume-title":"Handbook of emotion elicitation and assessment","author":"Bradley M.
