To investigate brain maintenance of deliberate deception the positron emission tomography and the event related functional MRI studies were performed. We used an experimental paradigm that presupposed free choices between equally beneficial deceptive or honest actions. Experimental task simulated the "Cheat" card game which aims to defeat an opponent by(More)
The generation of regular and irregular past tense verbs has long been a testing ground for different models of inflection in the mental lexicon. Behavioral studies examined a variety of languages, but neuroimaging studies rely almost exclusively on English and German data. In our fMRI experiment, participants inflected Russian verbs and nouns of different(More)
The goal of the study was analysis of the cerebral mechanisms of deliberate deception. The eventrelated functional magnetic resonance (ER fMRI) imaging technique was used to assess the changes in the functional brain activity by means of recording the blood oxygen level-dependent (BOLD) signal. Twelve right-handed healthy volunteers aged 19–44 years(More)
In this article, the characteristics of the functional activity of the anterior cingulate cortex (ACC), a key element of the neuroanatomical error detection system of the brain in drug-resistant forms of obsessive-compulsive disorder (OCD) are discussed on the basis of both original and published data. Available data indicate the presence of a functional(More)
In the present article it was shown that the functional connectivity of brain structures, revealed by factor analysis of resting PET CBF and rCMRglu data, is an adequate tool to study the default mode of the human brain. The identification of neuroanatomic systems of default mode (default mode network) during routine clinical PET investigations is important(More)
The goal of the present study was to investigate functional interactions between brain structures during deliberate deception. On the basis of the results obtained and literature data, the following hypothesis has been formulated: the functional interaction between the brain areas responsible for executive control of the behavior localized in the prefrontal(More)
The present paper dedicated to the research of the functional interactions between brain structures while executing deliberate deceptive actions. Based on our own and literature data, we formulated the hypothesis that the functional interaction between brain areas responsible for the executive control, localized in the prefrontal cortex (inferior frontal(More)
Functional connectivity between brain areas involved in the processing of complex language forms remains largely unexplored. Contributing to the debate about neural mechanisms underlying regular and irregular inflectional morphology processing in the mental lexicon, we conducted an fMRI experiment in which participants generated forms from different types(More)
Contemporary functional tomographic neuroimaging methods (fMRI and PET) have for many years been applied actively not only in basic studies of brain functions, but also in clinical practice. This article considers the main characteristics of the signals recorded and the principles of constructing images, as well as the requirements for obtaining adequate(More)
