Concomitant Strabismus

The role played by the extraocular muscles (EOMs) in the etiology of concomitant infantile strabismus is still debated and it has not yet definitively established if the sensory anomalies in concomitant strabismus are a consequence or a primary cause of the deviation. The commonest theory supposes that most strabismus results from abnormal innervation of the EOMs, but the cause of this dysfunction and its origin, whether central or peripheral, are still unknown. The interaction between sensory factors and innervational factors, that is, esotonus, accommodation, convergence, divergence, and vestibular reflexes in visually immature infants with family predisposition, is suspected to create conditions that prevent binocular alignment from stabilizing and strengthening. Some role in the onset of fixation instability and infantile strabismus could be played by the feedback control of eye movements and by dysfunction of eye muscle proprioception during the critical period of development of the visual sensory system. A possible role in the onset, maintenance, or worsening of the deviation of abnormalities of muscle force which have their clinical equivalent in eye muscle overaction and underaction has been investigated under either isometric or isotonic conditions, and in essence no significant anomalies of muscle force have been found in concomitant strabismus.

Dual Task Training

The ability of human beings to perform more than one task at a time has long been focus of study in the literature on human attention and memory. Older adults are more penalized when they must divide their attention between two input resources i.e input and holding or holding and responding. Falls have potentially devastating physical, social and psychological consequences. Falling is one of the most serious problems associated with ageing. Sensory system deteriorates with age, increased attention is allocated to “HIGHTEN” the signal coming from this system in order to gain necessary information for postural control. Older adults show marked reduction in the ability to perform the postural and cognitive task simultaneously. A study was conducted by physiotherapy and psychology students in a small town of Haryana on institutionalized older adults in which Dual task training under various sets of instruction that is Fixed priority and Variable priority instruction sets effects the balance who are living in residential care facilities. Tinneti Performance Oriented Mobility Assessment (POMA) and Mini mental status examination were used as tools to assess balance and cognitive abilities. Various studies related to the role of cognitive factors in balance impairments were reviewed. Data was analyzed using SPSS 13.0 software packages and paired sample t –test within the group and independent sample t – test between the groups with p – value at a significance level of p < 0.05 was used. The result of the study supported the hypothesis that there is significant improvement in balance of institutionalized elderly people who received dual task training with variable priority instruction set. (p < 0.001). The use of validated measurement tool like Tinnetti performance oriented mobility assessment on balance allowed clearer interpretation of the results. There is improvement in TPOMA Scores after 4 weeks training program in both groups. This shows that cognitive factors do play an important role in maintaining balance and coordination. Any impairment related to sensory system or cognition leads to balance impairments and increased risk for falls.

Chronic Pain Conditions

This article reviews some of the preclinical studies of the sympathetic nervous system’s role in arthritis, inflammatory, and neuropathic pain, in light of the emerging understanding of how the immune system, sensory system, and sympathetic system markedly affect each other’s function, with many mechanisms besides sprouting. Many studies show a pro-inflammatory and pro-nociceptive role for the sympathetic nerves in preclinical models. However, these studies are sometimes conflicting, and the role of the sympathetic nerves can sometimes be anti-inflammatory or anti-nociceptive, particularly at later stages or when systemic effects on immune tissues are considered. The article discusses human correlates of these preclinical studies, as well as some possible reasons for the many conflicting studies in the literature. The article argues that sympathetic-based interventions for chronic pain conditions hold promise despite the conflicting findings in the field, especially if better ways to define appropriate subsets of patients can be developed.

The Relationship

Summary The aim of this paper is to indicate the relationship between the shape of organizational sensory systems of Polish companies and beneficialness of the shape of cooperative relations between these companies with particular kinds of cooperators. The theoretical part of this article was devoted to the identification of the role of cooperative relations in the contemporary economic environment and a brief description of the concept of organizational sensory system, including its influence on cooperation between companies. The survey used the respondents’ indications of frequency of monitoring of elements of organization and its environment and the indication of the beneficialness of the shape of cooperative relationships with suppliers, customers and co-opetitors (in the framework of coopetitive relations). The chi-squared independence tests were used to demonstrate dependencies. In conclusion, it turned out that there are only two statistically significant relations and both of them pertain to relationships with customers.

Gustatory Perception

The subject of this paper is visual perception verbs in the Erzya-Mordvin and Finnish languages from the point of view of their semantic characteristics in comparison. Depending on the leading role of the sensory system, which, along with the visual system, plays a major role in perception, one distinguishes between auditory, tactile, olfactory and gustatory perception. This verbal group has a sensuous level of interrelations. Being verbs of perception, they are aimed at objects that have physical characteristics, whereas many of them are focused on the perception of concepts. In this regard, the verbs of perception develop a polysemy that goes in different directions. The novelty of the research lies in the comparative study of the lexical level of the Erzya-Mordvin and Finnish languages, which will allow us to tackle some theoretic aspects of Finno-Ugric linguistics in the future. The problem associated with the study of the semantics of perception verbs, or perceptual activity, is of relevance. Therefore, the purpose of this research is to describe the structure of the semantic field of verbs of one aspect of perception, namely the visual one: to determine the nuclear and peripheral verbal units using the material of the languages under study; to describe the system of meanings of verbal lexemes in the Erzya and Finnish languages, to analyze the polysemy of the studied verbal group in each of the above languages; to reveal additional semantic connotations in verbal lexemes; of particular interest is also the comparative study of the specifics of expression of the same semantic meaning in the context of far-related languages, in this case, Erzya and Finnish.

AbstractPassive electroreception is a complex and specialised sense found in a large range of aquatic vertebrates primarily designed for the detection of weak bioelectric fields. Particular attention has traditionally focused on cartilaginous fishes, but a range of teleost and non-teleost fishes from a diversity of habitats have also been examined. As more species are investigated, it has become apparent that the role of electroreception in fishes is not restricted to locating prey, but is utilised in other complex behaviours. This paper presents the various functional roles of passive electroreception in non-electric fishes, by reviewing much of the recent research on the detection of prey in the context of differences in species' habitat (shallow water, deep-sea, freshwater and saltwater). A special case study on the distribution and neural groupings of ampullary organs in the omnihaline bull shark, Carcharhinus leucas, is also presented and reveals that prey-capture, rather than navigation, may be an important determinant of pore distribution. The discrimination between potential predators and conspecifics and the role of bioelectric stimuli in social behaviour is discussed, as is the ability to migrate over short or long distances in order to locate environmentally favourable conditions. The various theories proposed regarding the importance and mediation of geomagnetic orientation by either an electroreceptive and/or a magnetite-based sensory system receives particular attention. The importance of electroreception to many species is emphasised by highlighting what still remains to be investigated, especially with respect to the physical, biochemical and neural properties of the ampullary organs and the signals that give rise to the large range of observed behaviours.
