The circles\u2010lines paradigm is used to study the bimanual coupling and interference effects: Participants simultaneously draw either lines or circles with both hands (congruent), or draw lines with one hand and circles with the other hand (incongruent condition). Despite extensive behavioral research on bimanual coupling with this paradigm, our knowledge of the neural circuitry involved remains limited. Here, we capitalized on the advantages provided by functional near\u2010infrared spectroscopy to unveil the neural substrates of bimanual coupling within an ecologically valid experimental setting. Behavioral results confirmed previous literature, showing that the shapes become more oval due to the interference between the hands, causing the circle to resemble a line and vice versa. Additionally, performance in the congruent condition correlated with performance in the incongruent condition. From a neural perspective, we observed greater activity in sensorimotor areas and the right premotor area during the incongruent compared to the congruent condition. A novel temporal analysis of the time course of oxyhemoglobin signals revealed that the right hemisphere reached maximum amplitude before the left during the incongruent condition and revealed differences between conditions in parietal areas, showing that bimanual interference is associated not only with motor areas but also with associative areas. Finally, right inferior parietal lobe activity correlated with bimanual performance, suggesting a role for this area in bimanual tasks when the motor program of one hand is influenced by sensorimotor information from the contralateral hand.<\/jats:p>","DOI":"10.1002\/hbm.70172","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T05:19:32Z","timestamp":1741756772000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Inferior Parietal Lobe Activity Reveals Bimanual Coupling and Interference"],"prefix":"10.1002","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4584-5149","authenticated-orcid":false,"given":"Costanza","family":"Iester","sequence":"first","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health University of Genoa  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Biggio","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health University of Genoa  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3032-7381","authenticated-orcid":false,"given":"Sabrina","family":"Brigadoi","sequence":"additional","affiliation":[{"name":"Department of Developmental and Social Psychology University of Padova  Padua Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ambra","family":"Bisio","sequence":"additional","affiliation":[{"name":"Department of Experimental Medicine, Section of Human Physiology University of Genoa  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giampaolo","family":"Brichetto","sequence":"additional","affiliation":[{"name":"Italian Multiple Sclerosis Foundation Scientific Research Area  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simone","family":"Cutini","sequence":"additional","affiliation":[{"name":"Department of Developmental and Social Psychology University of Padova  Padua Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Bonzano","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Rehabilitation, Ophthalmology, Genetics, Maternal and Child Health University of Genoa  Genoa Italy"},{"name":"IRCCS Ospedale Policlinico San Martino  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8129-4298","authenticated-orcid":false,"given":"Marco","family":"Bove","sequence":"additional","affiliation":[{"name":"Department of Experimental Medicine, Section of Human Physiology University of Genoa  Genoa Italy"},{"name":"IRCCS Ospedale Policlinico San Martino  Genoa Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnagi.2021.717002"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1364\/BOE.4.001366"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010021\u201094569\u20108"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2016.00488"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2005.10.011"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuroimage.2003.09.002"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bandc.2021.105753"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1255\/jnirs.969"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/12.11.1213"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031-9155\/33\/12\/008"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.22-12-05074.2002"},{"key":"e_1_2_10_13_1","first-page":"917","article-title":"The Neural Consequences of Conflict Between Intention and the Senses","volume":"29","author":"Fink G.
