The results of the previous fMRI study of word frequency effect in Russian contradicts with the results obtained in fMRI studies of English speakers. Two reasons for such inconsistency may be either task specificity (verb related task vs noun related task (tasks involving verbs vs. task involving nouns) or cross-linguistic differences. The purpose of this study was to examine fMRI correlates of word frequency in Russian using object naming task. We have found that several brain regions were more activated by retrieval of low frequency than high frequency words: fusiform gyrus, inferior occipital gyrus, middle occipital gyrus, supplementary motor area, inferior frontal gyrus bilaterally, left thalamus, left insula, right cingulate gyrus. At the same time we revealed no brain areas responding more to high frequency than low frequency words. These results are consistent with the previous fMRI studies in English. The present results also indicate the possible role of parts of speech as well as possible interactions of task and word frequency in brain mechanisms for word retrieval.

Структурно-функциональная организация использования глаголов и существительных в зависимости от стратегии их актуализации

Власова Р. М., Печенкова Е. В., Ахутина Т. В. и др. Вопросы психологии. 2012. № 4. С. 128-138.

The study of cerebral organization of usage of verbs and nouns was carried out by means of functional magnetic resonance imaging. The influence of strategy of word actualization (verbs and nouns extraction on paradigmatic and syntagmatic connections) and the level of automation of these processes on the pattern of cerebral cortex activation was shown.

Non-fluency represented in cerebrocerevellar network: an fMRI study of overt action naming in non-fluent aphasia

Dragoy O., Malyutina S., Ivanova M. et al. In bk.: International Symposium on Functional Neuroimaging: Basic Research and Clinical Applications. Abstracts. MSUPE, 2012. P. 36-38.

Key characteristics of non-fluent (Broca, motor) aphasia are, among others, verb finding difficulties and effortful speech output. These characteristics are related to different levels of speech production (lexical retrieval and motor execution). This study was aimed at identifying normative brain activation related to verb production in healthy individuals, as well as patterns of its reorganization depending on the locus of the linguistic deficit in patients with non-fluent aphasia.

ФМРТ-исследование функциональных связей головного мозга в задаче категоризации эмоциональных и нейтральных лиц

Королькова О. А., Печенкова Е. В., Синицын В. Е. В кн.: Когнитивная наука в Москве: новые исследования. Материалы конференции 15 июня 2017 г.. 2017. С. 174-179.

We analyzed brain functional connectivity using data from a task-based fMRI study of explicit categorization of neutral and emotional faces. During the perception of emotional faces, the correlation of BOLD signal in the right posterior superior temporal sulcus (STS) with other regions of the core face system increased, as compared to neutral faces. Conversely, during the perception of neutral faces, we found an increased correlation of STS and other core face system regions with brain areas outside the core system. The functional connectivity of STS shows lateralization due to the presence or absence of emotional expression. The obtained results support the key role of STS in facial expression recognition.

Neural correlates of personally familiar faces: Parents, partner and own faces

Human Brain Mapping. 2009. Vol. 30. No. 7. P. 2009-2020.

Investigations of the neural correlates of face recognition have typically used old/new paradigms where subjects learn to recognize new faces or identify famous faces. Familiar faces, however, include one's own face, partner's and parents' faces. Using event-related fMRI, we examined the neural correlates of these personally familiar faces. Ten participants were presented with photographs of own, partner, parents, famous and unfamiliar faces and responded to a distinct target. Whole brain, two regions of interest (fusiform gyrus and cingulate gyrus), and multiple linear regression analyses were conducted. Compared with baseline, all familiar faces activated the fusiform gyrus; own faces also activated occipital regions and the precuneus; partner faces activated similar areas, but in addition, the parahippocampal gyrus, middle superior temporal gyri and middle frontal gyrus. Compared with unfamiliar faces, only personally familiar faces activated the cingulate gyrus and the extent of activation varied with face category. Partner faces also activated the insula, amygdala and thalamus. Regions of interest analyses and laterality indices showed anatomical distinctions of processing the personally familiar faces within the fusiform and cingulate gyri. Famous faces were right lateralized whereas personally familiar faces, particularly partner and own faces, elicited bilateral activations. Regression analyses show experiential predictors modulated with neural activity related to own and partner faces. Thus, personally familiar faces activated the core visual areas and extended frontal regions, related to semantic and person knowledge and the extent and areas of activation varied with face type.
