fMRI correlates of the word frequency effect in Russian.

Vlasova R.M., Pechenkova E., Sinitsyn V.
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.
