{"pk":27504,"title":"Neural Phase Synchrony on Understanding Meanings of Symbols","subtitle":null,"abstract":"The establishment of symbolic communication system, i.e., making a shared meaning system from meaninglesssignals, is studied in experimental semiotics (Galantucci, 2005). Local neural activities within a brain region during a symboliccommunication task (Konno et al., 2013), where two participants try to establish a symbolic communication system fromscratch, has been studied (Li et al, 2015). It is, however, not certain how information bindings between different brain regionsis involved in a cognitive process associated with the establishment process. We analyzed EEG phase synchronization, as ameasure of functional connectivity, of participants engaged in the symbolic communication task. We found the recruitmentof fronto-occipital synchronization at 40 Hz frequency (gamma band), when a symbolic message was displayed, became fastwhen establishing a symbolic communication system. This finding suggests that frontal-occipital information binding by phasesynchronization becomes efficiently used in the course of mutual understanding of symbolic messages.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5mv461s2","frozenauthors":[{"first_name":"Masayuki","middle_name":"","last_name":"Fujiwara","name_suffix":"","institution":"Japan Advanced Institute of Science and Technology","department":""},{"first_name":"Takashi","middle_name":"","last_name":"Hashimoto","name_suffix":"","institution":"Japan Advanced Institute of Science and Technology","department":""},{"first_name":"Guanhong","middle_name":"","last_name":"Li","name_suffix":"","institution":"Japan Advanced Institute of Science and Technology","department":""},{"first_name":"Jiro","middle_name":"","last_name":"Okuda","name_suffix":"","institution":"Kyoto Sangyo University","department":""},{"first_name":"Takeshi","middle_name":"","last_name":"Konno","name_suffix":"","institution":"Kanazawa Institute of Technology","department":""},{"first_name":"Kazuyuki","middle_name":"","last_name":"Samejima","name_suffix":"","institution":"Tamagawa University","department":""},{"first_name":"Junya","middle_name":"","last_name":"Morita","name_suffix":"","institution":"Shizuoka University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27504/galley/17140/download/"}]}
