© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.We have implemented neurosemantic analysis to identify voxel-wise representations of lexical items in brain’s reaction of native participants on Russian spoken narratives and these representations possible global asymmetries in the brain. Twenty-five subjects took part in this study. Five texts with personal life stories were presented as audio stimuli. Each story was 2 min long. Ultrafast MRI sequences (TR = 1000 ms) were used to scan brain activity. Scanning was performed on 3 T MRI (Siemens). Seven subjects were selected for further analysis following the control of their cognitive involvement into listening and the level of their registered brain activity. As in an earlier our study with these narratives, twelve lexical clusters were found, with different but coherent semantic fields: from time-and-space concepts to human actions and mental states. The individual semantic maps of each subject look similar in terms of their broad brain activity distribution. Clusters demonstrated nearly symmetrical localization. This fact implies that the left and right hemispheres are both involved in the neural representation of mental lexicon.
