The given list was compiled in the frameworks of research on the neural basis of semantic representations. As reported by the authors, it resulted from clustering words from massive text corpora into 180 semantic groups, covering the entire semantic space of the corpora. The most representative concepts, manually selected from each cluster, were then used as input stimuli in three fMRI experiments in order to investigate the relationship between the linguistic representations and the resulting imaging data. The researchers report that semantic information is not confined to a specific brain region, as commonly assumed, but rather distributed across several high-level cortical networks.
