Main Components

The use of physiological signals is relatively recent development in human emotion recognition. Interest in this field has been motivated by the unbiased nature of such signals, which are generated autonomously from the central nervous system. Generally, these signals can be collected from the cardiovascular system, respiratory system, electrodermal activities, muscular system and brain activities. This paper presents an overview of emotion recognition using physiological signals. The main components of a physiological signals-based emotion recognirion system are explained, including discussion regarding the concepts and problems about the various stages involved in its framework.

♦ In children, bone is more flexible and heals faster than in adults but is at risk of growth disturbance. It is also capable of remodelling♦ The physis is weaker than the structures around it and therefore is liable to disruption in trauma♦ The possibility of injuries as a result of abuse must be considered in children and have a characteristic pattern♦ In poly trauma, children are more susceptible to hypothermia. Abdominal viscera and the cranium are more vulnerable. However, the central nervous system has more scope for recovery, and the cardiovascular system has an excellent capacity for coping with hypovolaemic shock♦ A reliable specific paediatric score should be used to plan treatment♦ The management of fractures is more likely to involve traction, plaster, and K-wires.

The Central Nervous System

Nerve Growth Factor (NGF) was initially studied for its role as a key player in the regulation of peripheral innervations. However, the successive finding of its release in the bloodstream of male mice following aggressive encounters and its presence in the central nervous system led to the hypothesis that variations in brain NGF levels, caused by psychosocial stressor, and the related alterations in emotionality, could be functional to the development of proper strategies to cope with the stressor itself and thus to survive. Years later this vision is still relevant, and the body of evidence on the role of NGF has been strengthened and expanded from trophic factor playing a role in brain growth and differentiation to a much more complex messenger, involved in psychoneuroendocrine plasticity.

Purpose: The aim is to study the bioelectric activity of the brain in the operational workers of the Novovoronezh and Beloyarsk nuclear power plants with a low level of psychophysiological adaptation. Material and methods: An EEG study of 101 operational employees of the NPP was conducted, visual and spectral analyses were used. EEG indicators of individuals with a low level of psychophysiological adaptation and low functional activity of structural and functional formations of the central nervous system were compared with those of individuals with a high level of adaptation, high functional activity of structural and functional formations of the central nervous system. Results: Visual analysis of individuals with a low level of psychophysiological adaptation revealed abnormal EEG indicators, indicating functional disorders of the central nervous system. The greatest violations were revealed in the structural and functional formation responsible for the central regulation of the cardiovascular system. A comparative assessment of the spectral power of the EEG at different levels of psychophysiological adaptation revealed a state of tension (tense adaptation) observed in individuals with both low and high levels of adaptation. The similarity between the structural and functional formation "central regulation of the cardiovascular system" with low functional activity and a low level of psychophysiological adaptation in terms of the number of abnormal EEG indicators can be considered as evidence of its greatest contribution to the formation of a low level of adaptation.The evaluation of interhemispheric interactions in structural and functional formations at their low and high activity, as well as at low and high levels of adaptation, suggested that the formation of a high level of psychophysiological adaptation as an integral characteristic of the main role played by the formation of the "Cortex" and "central regulation of the cardiovascular system". In the formation of a low level of psychophysiological adaptation as an integral characteristic, the main role is played by the formations "cortex" and "cortical-subcortical interaction". Conclusion: A violation of the bioelectric activity of the brain may be one of the pathogenetic mechanisms of reduced adaptation. The presence of statistically significant differences in EEG indicators in individuals with low and high levels of adaptation, revealed by visual and spectral analysis, allows us to consider these indicators as informative not only in terms of identifying deviations in the diagnosis of functional disorders, but also in assessing the effectiveness of rehabilitation and health measures.

Extensive experimental and clinical material cited in the modern scientific literature indicates the effect of sex hormones on the cardiovascular system and the need to take into account changes in its activity during therapy with drugs containing these biologically active substances [3, 5, 7, 71]. Along with the numerous compounds mediated through the structures of the central nervous system and circulating in the circulatory system, the genomic vasoactive effects of all steroid compounds, including sex hormones, can be realized due to the direct effect on the vascular wall [55, 66, 71, 75].

ABSTRACT Nipah virus, a newly emerged zoonotic paramyxovirus, infects a number of species. Human infections were linked to direct contact with pigs, specifically with their body fluids. Clinical signs in human cases indicated primarily involvement of the central nervous system, while in pigs the respiratory system was considered the primary virus target, with only rare involvement of the central nervous system. Eleven 5-week-old piglets were infected intranasally, orally, and ocularly with 2.5 × 105 PFU of Nipah virus per animal and euthanized between 3 and 8 days postinoculation. Nipah virus caused neurological signs in two out of eleven inoculated pigs. The rest of the pigs remained clinically healthy. Virus was detected in the respiratory system (turbinates, nasopharynx, trachea, bronchus, and lung in titers up to 105.3 PFU/g) and in the lymphoreticular system (endothelial cells of blood and lymphatic vessels, submandibular and bronchiolar lymph nodes, tonsil, and spleen with titers up to 106 PFU/g). Virus presence was confirmed in the nervous system of both sick and apparently healthy animals (cranial nerves, trigeminal ganglion, brain, and cerebrospinal fluid, with titers up to 107.7 PFU/g of tissue). Nipah virus distribution was confirmed by immunohistochemistry. The study presents novel findings indicating that Nipah virus invaded the central nervous system of the porcine host via cranial nerves as well as by crossing the blood-brain barrier after initial virus replication in the upper respiratory tract.

Introduction. The study's relevance is due to the need to improve the safety of nuclear industry enterprises and, as a consequence, to ensure a good level of psychophysiological functioning of employees. The study aims to identify the analysis of EEG indicators characterizing the FS of the central nervous system at different levels of PFA using visual and computer analysis. Materials and methods. Object - 331 archival EEGS of workers of hazardous radiation industries. The researchers determined the level of adaptation of employees using psychological, psychophysical, and physiological techniques. We conventionally recorded the EEG at rest and functional loads. In addition, scientists used a visual analysis and computer evaluation of the spectral power of EEG biopotentials in the processing. Results. With the help of visual analysis, we identified diagnostic features reflecting different levels of psychophysiological adaptation and functional activity of structural and functional formations of the central nervous system. It is possible to determine the role of structural and functional formations in forming a low level of adaptation and formulate prognostic criteria for adaptation. Researchers have identified some mechanisms of these criteria based on the evaluation results of the spectral power of EEG biopotentials. Conclusions. We identified four abnormal indicators in the EEG: "Type IV EEG", "Unstable EEG dynamics", "High index of β1 activity", "Presence of flashes of bilateral synchronous waves". These indicators indicate the presence of violations of the central regulation of the cardiovascular system and dysfunctional changes in the structures of the limbic-reticular complex. Therefore, we consider it as a criterion of a low level of PFA. The identification in the EEG of persons with a high level of PFA electroencephalographic norm indicates the absence of violations of the central regulation of the cardiovascular system and dysfunctional changes in the structures of the limbic-reticular complex. Researchers consider this a sign of a high probability of these individuals performing professional activities with a low risk of emergencies due to reduced adaptation.
