The Default Mode Network (DMN) is a brain system that mediates internal modes of cognitive activity, showing higher neural activation when one at rest. Nowadays, there lot interest in assessing functional interactions between its key regions, but the majority studies only association BOLD (Blood-oxygen-level dependent) patterns measured, so it impossible to identify causal influences. There are some (i.e. effective connectivity), however often with inconsistent results. aim current work find...
The purpose of this paper was to study causal relationships between left and right hippocampal regions (LHIP RHIP, respectively) within the default mode network (DMN) as represented by its key structures: medial prefrontal cortex (MPFC), posterior cingulate (PCC), inferior parietal (LIPC) (RIPC) hemispheres. Furthermore, we were interested in testing stability connectivity patterns when adding or deleting interest. functional magnetic resonance imaging (fMRI) data from a group 30 healthy...
was to analyze the immune-inflammatory profile of patients with paranoid schizophrenia and relate it severity negative symptoms MRI data in order identify biomarkers severity, search for new approaches therapy, control its effectiveness.
Lateral asymmetry is one of the fundamental properties functional anatomy human brain. Amygdala (AMYG) was also reported in clinical studies resting-state connectivity (rsFC) but rarely healthy groups. To explore this issue, we investigated reproducibility data on rsFC left and right AMYG using MRI twice a week 20 volunteers with mild-to-moderate anxiety. We found network AMYG, which included regions involved emotional processing several other brain areas associated memory motor inhibition....
<p>This work presents the results of studying evaluation fMRI data at group level. Some factors influencing formation such estimates are shown. On basis experimental obtained in forensic tests information concealment paradigm, attention is drawn to need for a critical assessment and methodology (design) research, based on which outcome analysis level presented.</p>
In the present study, we combine linguistic annotation of oral texts in Russian with registration BOLD signal functional MRI experiments to determine how and where semantic categories are represented human brain.Using same stimuli material, also analyze differences cortical activation three thematic domains: description nature, working principles technical devices more self-referential texts, addressing question identity conflict situations.We discuss methodological problems within two...
Recently, the dynamic properties of brain activity rather than its stationary values have attracted more interest in clinical applications. It has been shown that signals exhibit scale-free dynamics or long-range temporal correlations (LRTC) differ between rest and cognitive tasks healthy controls groups. Little is known about how fear-inducing may influence dispersion LRTC subsequent resting-state activity. In this study, we aimed to explore changes variance brain's blood oxygenation...
In this work, the investigation of network activity mirror neurons systems in animal brains depending on experience (existence or absence performance shown actions) was carried out. It out research C57/BL6 line mice supervision task swimming mice-demonstrators Morris water maze. showed presence motor cortex M1, M2, cingular cortex, hippocampus groups, having and without it. The conclusion is drawn about possibility new functional formation by means acquisition knowledge through animals...
The aims of the project were to study architecture brain's neural networks in process perceiving individual stimuli that are personally significant, evaluate main parameters immunity and systemic inflammation, relate those brain damage markers patterns cognitive-affective disorders patients with schizophrenia.Materials Methods.The involved 35 paranoid schizophrenia 17 people without cognitive impairment.Clinical information about was obtained from database created Alekseev Psychiatric...
Objective To search for the relationship between results of functional imaging, immunological parameters and laboratory markers inflammation in schizophrenia, taking into account cognitive impairment patients, to consider possibility using a multidisciplinary approach diagnosis, treatment prognosis schizophrenia. Material methods The study included 25 patients with schizophrenia 13 healthy volunteers. Psychiatric scales were administered evaluate patient's condition. main indicators humoral...
Schizophrenia is a chronic disease characterized by psychosis, behavioral, cognitive and social impairments. It accompanied structural functional changes in the brain. To confirm significance of morphometric changes, it important to establish relationships between brain, clinical symptoms, level biomarkers reflecting pathogenesis disease, including immunological markers. The aim this work was assess relationship interleukin-6 (IL-6) levels with systemic inflammation, immune activation...
<p>When analyzing physiological signals, the problem of setting data processing parameters arises due to blurring boundary between signal and noise properties, as well fundamental lack objective criteria for quality in psychophysiology. This paper describes an approach optimizing on example galvanic skin response (GSR) photoplethysmogram (PPG), based use stimuli that are significant a person, selected basis biographical data, which can be considered validation. As metric optimization,...
Insight is described as the sudden solution of a problem and contrasted with an analytical, step-by-step approach. Traditionally, insight thought to be associated activity right hemisphere, whereas analytical solutions are left hemisphere. However, empirical evidence localization insight-related brain mixed inconclusive. Some studies seem confirm traditional view, others do not. Moreover, results EEG fMRI frequently contradict each other. In this study, data were recorded while subjects...
In this paper, an interesting case of spinal pathology is considered. 2015, under the supervision V.V. Cherevko, archaeological excavations were carried out on territory a cemetery near village Vaskovi-chi, Glubokoye district, Vitebsk region (Republic Belarus). course excavations, two burials discovered, which date back to end 19th century. The remains from burial 2 belonged relatively young male, lying his with hands stretched down and spine unnaturally curved in lumbar region. To diagnose...
This study is part of a large interdisciplinary project to create objective criteria for building classification system polymorphic schizophrenic disease characterized by disorders thinking and perception. Within the framework project, first time in patients with schizophrenia hallucinatory-delusional syndrome, neuropsychological testing, complete structural (morphometry tractography) functional MRI studies involving detailed clinical study, determination patient's immunological genetic...
