fMRI correlates of the word frequency effect in Russian.
Humanities. HUM. Basic Research Programme , 2013. No. 2.
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.

The retrieval of low frequency words is usually slower than that of high frequency words. Neuroimaging research on the role of word frequency in linguistic tasks suggests candidate brain areas for the neural substrates of this effect. The only previous fMRI study of word frequency in Russian (Malutina et al., 2012) used an action naming ...

Previous clinical research has shown a positive effect of instrumentality on verb retrieval in individuals with aphasia. Performance on instrumental verbs incorporating an obligatory tool into their conceptual representation (e.g., to cut) is more accurate compared to non-instrumental verbs (e.g., to tear), possibly due to more specific conceptual representations of instrumental verbs. Seeking the neural correlates of ...

Many studies suggest that social punishment is beneficial for cooperation and consequently maintaining the social norms in society. Neuroimaging and brain stimulation studies show that the brain regions which respond to violations of social norms, the understanding of the mind of others and the executive functions, are involved during social punishment. Despite the rising number ...

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 ...

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 ...

When touching different objects, we process their emotional qualities: some objects are pleasant to the touch, while others are not. The neural correlates of affective processing of touch are mostly investigated via stimulation of CT afferents, which innervate only hairy skin and encode affective properties of the stimuli. However, emotional qualities of touch can be ...

Глаголы физического действия (англ. motor verbs) – это семантический класс глаголов, обозначающих действие, выполняемое какой-либо частью тела (например, рвать, щекотать). Инструментальные глаголы (англ. instrumental verbs) обозначают действие, для выполнения которого необходимо использование инструмента, не являющегося частью тела (например, пилить, вязать); являются подклассом глаголов физического действия. Представляет интерес то, связана ли обработка глаголов этих семантических классов ...

Social norms have a critical role in everyday decision-making, as frequent interaction with others regulates our behavior. Neuroimaging studies show that social-based and fairness-related decision-making activates an inconsistent set of areas, which sometimes includes the anterior insula, anterior cingulate cortex, and others lateral prefrontal cortices. Social-based decision-making is complex and variability in findings may be ...

Functional connectivity between salience, default mode and frontoparietal networks in post-stroke depression
Journal of Affective Disorders 2018 Vol. 227 P. 554-562
BACKGROUND: Previous studies have demonstrated altered resting state functional connectivity (rsFC) in patients with post-stroke depression (PSD). It remains unclear whether rsFC is changed at the network level as was shown for major depressive disorder (MDD). To address this question, we investigated rsFC of resting sate networks (RSNs) in PSD. METHODS: Eleven subjects with PSD underwent fMRI scanning ...
