The specific features of the topology of spectral powers and coherent interregional interrelationships in the narrow, individually determined δ-, θ-, α1-, α2-, and α3-frequency bands were studied by means of high-resolution EEG (62 channels) in novice and experienced meditators (NMs and EMs) at rest and under the conditions of generation of an altered state(More)
This study examines the effects of cognitive reappraisal on the cardiovascular response to affective stimuli. Participants (N = 53) were shown affective images and were asked either to attend to the images, or to downregulate negative affect through reappraisal of negative images or upregulate positive affect through reappraisal of positive images while(More)
BACKGROUND Tardive dyskinesia is a disorder characterized by involuntary muscle movements that occur as a complication of long-term treatment with antipsychotic drugs. It has been suggested to be related to a malfunctioning of the indirect pathway of the motor part of the cortical-striatal-thalamic-cortical circuit, which may be caused by oxidative(More)
The influence of polymorphic variations of the gene encoding serotonin transporter (5-HTT) on individual characteristics of cerebral hemodynamics (detected by means of functional magnetic resonance imaging (fMRI) under conditions of the performance of the tasks of the “Stop–Signal” experimental paradigm) was studied in the work. The 5-HTT gene polymorphic(More)
OBJECTIVES Variable-number tandem repeat (VNTR) polymorphisms of DRD4 and DAT genes were studied in the Russian and Chechen men convicted of crimes, and two control groups comprised of the MMA fighters and a sample of general population. A group of MMA fighters included only the subjects without history of antisocial behaviour. METHODS DNA was isolated by(More)
An association of the level of personal anxiety with polymorphic variants of the gene encoding serotonin transporter (5-HTT) in 57 Russian residents of Siberia and 62 Tuvinians was studied. The 5-HTT gene polymorphic variants were determined be means of allele-specific PCR with DNA isolated from the blood of subjects as a matrix. The level of explicit(More)
Meditation has been found to be an efficient strategy for coping with stress in healthy individuals and in patients with psychosomatic disorders. The main objective of the present study was to investigate the psychophysiological mechanisms of beneficial effects of meditation on cardiovascular reactivity. We examined effects of long-term Sahaja Yoga(More)
OBJECTIVES The aim of this study was to investigate a possible association between tardive dyskinesia (TD) and CYP1A2 (*1F, -163C>А, rs762551) polymorphism in Russian psychiatric inpatients. METHODS TD was assessed cross-sectionally using the Abnormal Involuntary Movement Scale (AIMS). Orofacial and limb-truncal dyskinesia were assessed with AIMS 1-4 and(More)
