Studies have suggested that alpha\u2013beta power decreases may index word\u2010retrieval processes. In context\u2010driven word retrieval, participants hear lead\u2010in sentences that either constrain the final word (\u2018He locked the door with the\u2019) or not (\u2018She walked in here with the\u2019). The last word is shown as a picture to be named. Previous studies have consistently found alpha\u2013beta power decreases prior to picture onset for constrained relative to unconstrained sentences, localised to the left lateral\u2010temporal and lateral\u2010frontal lobes. However, the relative contribution of temporal versus frontal areas to alpha\u2013beta power decreases is unknown. We recorded the electroencephalogram from patients with stroke lesions encompassing the left lateral\u2010temporal and inferior\u2010parietal regions or left\u2010lateral frontal lobe and from matched controls. Individual participant analyses revealed a behavioural sentence context facilitation effect in all participants, except for in the two patients with extensive lesions to temporal and inferior parietal lobes. We replicated the alpha\u2013beta power decreases prior to picture onset in all participants, except for in the two same patients with extensive posterior lesions. Thus, whereas posterior lesions eliminated the behavioural and oscillatory context effect, frontal lesions did not. Hierarchical clustering analyses of all patients\u2019 lesion profiles, and behavioural and electrophysiological effects identified those two patients as having a unique combination of lesion distribution and context effects. These results indicate a critical role for the left lateral\u2010temporal and inferior parietal lobes, but not frontal cortex, in generating the alpha\u2013beta power decreases underlying context\u2010driven word production.<\/jats:p>","DOI":"10.1111\/ejn.13695","type":"journal-article","created":{"date-parts":[[2017,9,9]],"date-time":"2017-09-09T05:36:37Z","timestamp":1504935397000},"page":"2622-2629","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Lesion evidence for a critical role of left posterior but not frontal areas in alpha\u2013beta power decreases during context\u2010driven word production"],"prefix":"10.1111","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4860-5952","authenticated-orcid":false,"given":"Vit\u00f3ria","family":"Piai","sequence":"first","affiliation":[{"name":"Donders Institute for Brain, Cognition and Behaviour Donders Centre for Cognition Radboud University Montessorilaan 3 6525 HR Nijmegen the Netherlands"},{"name":"Department of Medical Psychology Radboudumc Nijmegen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joost","family":"Rommers","sequence":"additional","affiliation":[{"name":"Donders Institute for Brain, Cognition and Behaviour Donders Centre for Cognitive Neuroimaging Radboud University Nijmegen the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert T.","family":"Knight","sequence":"additional","affiliation":[{"name":"Helen Wills Neuroscience Institute and Department of Psychology University of California Berkeley Berkeley CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,10,5]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cortex.2012.03.001"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1162\/0898929053279469"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhp055"},{"key":"e_1_2_9_5_1","unstructured":"Boersma P.&Weenink D.(2013).Praat: doing phonetics by computer(Version 5.3.42).
