报告简介🫲🏻：

The neuroscience literature has devoted many studies to the semantic processing of words. However, the research remains specific to certain categories, studied separately, and does not address the lexicon as a system. I will present a method of automatic language processing aimed at studying concepts and their processing, not in a category-by-category fashion, but as a system taken as a whole. The notion of system is a key feature in linguistics in order to describe the semantic of words. The method is based on correspondence analysis (CA), a data-analysis method commonly used in computational linguistics. Here, it was applied to the electrophysiological signals. This method permits: (a) to find the neural spatio-temporal networks that participated to the processing of the stimuli-words and that characterize their semantic similarities and differences; (b) to give a big picture of the structural organization of this processing; (c) to compare the organization revealed by the two processes: word-usage and neurophysiological word-processing. The method is general and could be applied in other neurophysiological experiments and with other types of data (fMRI, MEG,..).
