- Аннотация: Introduction. The early cognitive control model included inhibition, shifting and updating (Miyake, Friedman, 2000). Later a common executive factor (CEF) was proposed instead inhibition (Friedman, Miyake, 2016). The aim of this study is to reveal brain contribution to CEF that is considered to be related to activated relevant information but not inhibited irrelevant information. Methods. 34 right-handed participants performed classical Stroop (CS) and modified Stroop (MS) tasks. They recognized a font color of the Russian words “red” and “green” written in red or green font. In MS participants inhibited the response to the word “red” and responded only to the word “green”. The fMRI data were obtained using a 3T scanner SIEMENS Magnetom Verio (T2*-weighted, 65 slices, TR/TE=2200/25 ms, slice thickness=2 mm, FA=90°, MB 5, CMRR, block design) and processed using SPM12 (p FWE < 0.05). Results. Activated areas were observed in left supplementary motor cortex, thalamus bilaterally, right supramarginal gyrus, left posterior orbital gyrus, right precentral gyrus (CS); right angular gyrus, left supplementary motor cortex, right middle frontal gyrus, left superior parietal lobule, left putamen, right anterior insula, left opercular part of inferior frontal gyrus (MS). Right precuneus, right angular gyrus were more activated in MS. Conclusions. Both tasks involved CEF (frontal areas), but inhibition of responses in MS-task increased activation in areas related to relevant stimuli processing but not the frontal regions that may be associated with irrelevant information suppression. The research was financially supported by the Russian Science Foundation, project No 16-18-00066, and the Supercomputing Center of Lomonosov Moscow State University (non-financially)
