However, the neural underpinnings of repetition priming for famous faces in terms of effective connectivity are not known. Here we investigated this problem using dynamic causal modelling of latency\u2010corrected event\u2010related brain potentials (<jats:styled-content style=\"fixed-case\">RERP<\/jats:styled-content>s). Source waveforms of <jats:styled-content style=\"fixed-case\">RERP<\/jats:styled-content>\u2010derived sources in the Occipital Lobe, Fusiform Gyrus, Mediotemporal Lobe, Prefrontal Cortex and Anterotemporal Lobe of each hemisphere entered into models with only forward (F) or also with backward (<jats:styled-content style=\"fixed-case\">FB<\/jats:styled-content>) connections. Based on the framework of predictive coding formulated for repetition suppression, modulations of F and <jats:styled-content style=\"fixed-case\">FB<\/jats:styled-content> connections were expected for sources that displayed priming effects in their source waveforms. Hence, neural sources in each hemisphere were fitted with either F or <jats:styled-content style=\"fixed-case\">FB<\/jats:styled-content> connections. Inter\u2010hemispheric connections were considered between homologous areas and were allowed to be modulated in an incremental manner resulting in a model space that comprised of 24 models. Bayesian model averaging across models revealed effective bidirectional connectivity between the Fusiform Gyrus (face perception) and Prefrontal Cortex (decision\u2010making) in both hemispheres to be modulated by priming. In the left hemisphere, there is also a substantial involvement from the Mediotemporal Lobe, indicating the facilitation of automatic retrieval of the famous person's name. Furthermore, there is evidence that the priming is supported by connections from the right to the left Fusiform Gyri possibly in the service of inter\u2010hemispheric cooperation. Altogether, the study indicates that along with top\u2013down modulations, efficient processing within and across the two hemispheres is crucial for famous face priming.<\/jats:p>","DOI":"10.1111\/ejn.14303","type":"journal-article","created":{"date-parts":[[2018,12,14]],"date-time":"2018-12-14T13:37:39Z","timestamp":1544794659000},"page":"1330-1347","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Repetition priming effects for famous faces through dynamic causal modelling of latency\u2010corrected event\u2010related brain potentials"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5967-2173","authenticated-orcid":false,"given":"Rajan","family":"Kashyap","sequence":"first","affiliation":[{"name":"Department of Physics Hong Kong Baptist University  Kowloon Tong Hong Kong"},{"name":"Centre for Nonlinear Studies and The Beijing\u2013Hong Kong\u2013Singapore Joint Centre for Nonlinear and Complex Systems (Hong Kong) Institute of Computational and Theoretical Studies Hong Kong Baptist University  Kowloon Tong Hong Kong"},{"name":"Department of Electrical and Computer Engineering ASTAR\u2010NUS Clinical Imaging and Research Centre Singapore Institute for Neurotechnology and Memory Networks Program National University of Singapore  Singapore City Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sagarika","family":"Bhattacharjee","sequence":"additional","affiliation":[{"name":"Department of Psychology Nanyang Technological University  Singapore City Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Werner","family":"Sommer","sequence":"additional","affiliation":[{"name":"Department of Psychology Humboldt\u2010Universit\u00e4t zu Berlin  Berlin Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changsong","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Physics Hong Kong Baptist University  Kowloon Tong Hong Kong"},{"name":"Centre for Nonlinear Studies and The Beijing\u2013Hong Kong\u2013Singapore Joint Centre for Nonlinear and Complex Systems (Hong Kong) Institute of Computational and Theoretical Studies Hong Kong Baptist University  Kowloon Tong Hong Kong"},{"name":"Beijing Computational Science Research Center  Beijing China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,1,20]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2010.0349"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1778-08.2008"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0507062103"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhm140"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2012.10.038"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1162\/jocn_a_00263"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nicl.2016.01.006"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1080\/02724980543000150"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/13576500802383709"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1006\/smns.1996.0007"},{"key":"e_1_2_11_12_1","doi-asserted-by":"crossref","first-page":"1330","DOI":"10.1207\/s15516709cog2301_1","article-title":"From pixels to people: A model of familiar face recognition","volume":"23","author":"Burton A.
