Аннотация:This report is a part of a large-scale brain mapping project aimed at finding the correspondence between the semantic categories in a presented oral text and the brain activity, registered in fMRI scanner (Velichkovsky et al. 2020). For the experiment we have prepared 15 texts in Russian. Professional audio recordings of these texts were presented to subjects in fMRI. Our hypothesis is that semantically related words and concepts could be revealed in closely located or even the same brain areas. Here, we describe the implemented methods for semantic markup of texts, based on different understandings of semantic proximity.
