Executive functions are an important ability of human brain to program, regulate and control various cogni tive processes; one of these processes is the voluntary task switching. However, the sex differences in this pro cess are poorly studied. In our study, these differences were investigated in 70 healthy subjects (36 men and 34 women) aged 21–48 years by means of functional magnetic resonance imaging (fMRI) and neuropsycho logical examination. During the fMRI study, the subjects had to shift their attention between two tasks (clas sifying figures according to their form or number). During neuropsychological examination, the subjects completed a series of visual attention, task switching and memory tests. The results of fMRI study showed that visual task switching in women is carried out by a neuronal network, consisting of dorsolateral prefrontal cortex, inferior parietal areas, secondary visual areas of both hemispheres and cerebellum cortex. Task switching in men involved the same areas and, in addition, right supplementary motor area, right insula and left thalamus. As compared with women, the rate of activation of prefrontal cortex, left parietal lobe and right insula in men was significantly higher. The results of neuropsychological tests showed that men completed the tasks with attention switching, searching and arranging of stimuli significantly slower than women. The data demonstrate the differences in the organization of task switching processes in men and women.

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 ...

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 confidence in our retrieved memories, ie retrospective confidence, is a metamemory process we perform daily. There is a wide variety of applied research focused on these metamemory judgments and very diverse studies including a wide a range of clinical populations. Yet, the neural correlates that support its functioning are not well defined. We used ...

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives—an evolutionary psychological perspective and a biosocial role perspective—offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, ...

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 ...

Recent studies show that executive functions play an essential role in different strategies of emotion regulation (ER). The present study explored updating of information in working memory as a possible cognitive basis of cognitive reappraisal. Updating of affective information was examined, in particular, because cognitive tasks using affective material might be more relevant for the ...

Executive functions (EF) are a set of higher order cognitive processes that are engaged in a goal directed behaviour. It has been suggested that these functions work differently depending on the type of stimuli (non-affective or affective). Although there are many studies where EF measures have been used for affective or non-affective stimuli, the obtained results ...

fMRI language mapping studies report right-hemispheric contribution to language in healthy individuals. However, it remains unclear whether these right-hemispheric patterns of activity are critical for language, which is highly relevant for clinical preoperative language mapping. The available findings are controversial. In this study, we first measured individual patterns of language lateralization with an fMRI language localizer ...
