Essential processes for simple calculation are related to the spreading of activation through arithmetic memory networks. There is behavioral and electrophysiological evidence for these mechanisms. Their brain location is, however, still uncertain. Here, we measured magnetoencephalographic brain activity during the verification of simple multiplication problems. Following the operands, the solutions to verify could be preactivated correct solutions, preactivated table-related incorrect solutions, or unrelated incorrect solutions. Brain source estimation, based on these event-related fields, revealed 3 main brain networks involved in simple calculation: 1) bilateral inferior frontal areas mainly activated in response to correct, matching solutions; 2) a left-lateralized frontoparietal network activated in response to incorrect table-related solutions; and (3) a strikingly similar frontoparietal network in the opposite hemisphere activated in response to unrelated solutions. Directional functional connectivity analyses revealed a bidirectional causal loop between left parietal and frontal areas for table-related solutions, with frontal areas explaining the resolution of arithmetic competition behaviorally. Hence, this study isolated at least 3 neurofunctional networks orchestrated between hemispheres during calculation.<\/jats:p>","DOI":"10.1093\/cercor\/bhaa283","type":"journal-article","created":{"date-parts":[[2020,9,5]],"date-time":"2020-09-05T19:10:15Z","timestamp":1599333015000},"page":"1149-1162","source":"Crossref","is-referenced-by-count":9,"title":["Neurofunctional Components of Simple Calculation: A Magnetoencephalography Study"],"prefix":"10.1093","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0873-5357","authenticated-orcid":false,"given":"Elena","family":"Salillas","sequence":"first","affiliation":[{"name":"Department of Neurosciences, University of Padova, 35128 Padova, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Piccione","sequence":"additional","affiliation":[{"name":"IRCCS San Camillo Hospital, 30126 Venice, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia","family":"di Tomasso","sequence":"additional","affiliation":[{"name":"IRCCS San Camillo Hospital, 30126 Venice, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Zago","sequence":"additional","affiliation":[{"name":"IRCCS San Camillo Hospital, 30126 Venice, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6270-6883","authenticated-orcid":false,"given":"Giorgio","family":"Arcara","sequence":"additional","affiliation":[{"name":"IRCCS San Camillo Hospital, 30126 Venice, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Semenza","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, University of Padova, 35128 Padova, Italy"},{"name":"IRCCS San Camillo Hospital, 30126 Venice, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,10,26]]},"reference":[{"key":"2021010606005765300_ref1","doi-asserted-by":"crossref","first-page":"2382","DOI":"10.1016\/j.neuroimage.2010.10.009","article-title":"Is 2+2=4?
