The aim of this paper is to study the recognition of facial expression of emotions in depressed patients with major depressive disorder (MD) and schizotypal personality disorder (STP). The pictures of sad, emotionally neutral, and happy faces followed by a masking stimulus were displayed for 80 msec on a computer screen randomly in the left or right(More)
The aim of the study was to obtain some experimental evidence of the 'scanning hypothesis' that links electroencephalogram (EEG) alpha-activity with rhythmically spreading waves in the visual cortex. The hypothesis was tested in experiments with 29 healthy adults. Under flicker stimulation through closed lids with the frequency of the individual(More)
In four adult healthy subjects in 18 experiments, we studied Brain-Computer-Interface recognition of different intended words by P300 wave in the VEP. The set of optimal characteristics of visual stimulation which rise reliability of recognition up to 100 %, as well as effective registration locus (Pz) were determined. It was found that the best processing(More)
A reaction time and accuracy of visual recognition of emotions of joy, anger and fear in their relation to personality traits was studied in 68 healthy subjects. According to scores of Kettell Questionnaire all the participants were divided into two groups: emotionally unstable and emotionally stable, which differed in their emotional and communication(More)
Emotional reactivity of patients with endogenous depression and healthy test subjects towards classic and rock music was compared. According to the questionnaire data and EEG recording, it was established that in depressed patients, analysis and estimation of the emotionally significant information differ from those in healthy persons. In contrast to(More)
In psychophysical and neurophysiological experiments, the subjects recognized images of two categories, “animals” and “objects.” The images of the same categories differing from the target stimuli were used as the masking stimuli. We found that the efficacy of forward-masking depended on categorical similarity of the masking and target stimuli. The(More)
The accuracy, reaction time, and evoked potentials have been analyzed in 16 men and 15 women during recognition of familiar objects at different levels of spatial transformation. Three levels of transformation have been used: in a fixed position relative to each other, all details were shifted in the radial direction (level 1) followed by analogous(More)
Orientation sensitivity in the human visual system was studied in three experiments. In the first experiment, 134 subjects determined orientation of the segments of short lines by selecting it from a set of reference orientations (the Benton test). In the second experiment, 41 subjects of those who passed the Benton test determined the proximity of oblique(More)
In the review of modern data and ideas concerning the neurophysiological mechanisms and morphological foundations of the most essential communicative function of humans and monkeys, that of recognition of faces and their emotional expressions, the attention is focussed on its dynamic realization and structural provision. On the basis of literature data(More)
Two DNA bases, 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (hmC), marks of epigenetic modification, are recognized in immobilized DNA strands and distinguished from G, A, T and C by nanopore current recording. Therefore, if further aspects of nanopore sequencing can be addressed, the approach will provide a means to locate epigenetic modifications in(More)
