The Relationship

A review of research on intelligence testing with blind persons is presented. Comparisons between sighted and various visually impaired groups are made. The relationship between intelligence and blind subgroups is analyzed: Congenital and adventitious, degree of vision, visual diagnosis, attendance at residential versus public schools, length of education, family and social status. While sighted and visually impaired groups are similar in mean IQ scores, evidence was found to support the notion of intellectual factors that are differentially developed in the blind. Subgroup comparisons within the blind population suggest differences on the basis of age, education, and damage to the central nervous system.

The Relationship

The hypothesis is introduced that miniaturization of neuronal circuits in the central nervous system and the hierarchical organization of the various levels, where information handling can take place, may be the key to understand the enormous capability of the human brain to store engrams as well as its astonishing capacity to reconstruct and organize engrams and thus to perform highly sophisticated integrations. The concept is also proposed that in order to understand the relationship between the structural and functional plasticity of the central nervous system it is necessary to postulate the existence of memory storage at the network level, at the local circuit level, at the synaptic level, at the membrane level, and finally at the molecular level. Thus, memory organization is similar to the hierarchical organization of the various levels, where information handling takes place in the nervous system. In addition, each higher level plays a role in the reconstruction and organization of the engrams stored at lower levels. Thus, the trace of the functionally stored memory (i.e. its reconstruction and organization at various levels of storage) will depend not only on the chemicophysical changes in the membranes of the local circuits but also on the organization of the local circuits themselves and their associated neuronal networks.

□ Visual impairment is not necessarily blindness and the requirements of visually impaired persons are in many ways significantly different from those of blind persons. All too often agencies for the blind have not distinguished between these different requirements in providing services. The essential difference is that blind persons must rely on their other senses in order to function, while partially sighted persons must be helped to use whatever vision they have in coordination with their other senses. In providing services to partially sighted persons, the following basic principles should be considered: 1) Full service requires the cooperation of medical, physical, and behavioral specialists; 2) Services for partially sighted clients should be individualized on the basis of their differences in degree and quality of sight; 3) Whatever vision the client has should be augmented or strengthened through either mechanical or physical means; and 4) Clients should be helped to enhance their perception to its maximum functional potential.

SUMMARY AIM: the present study analysed the association between Zika-virus and microcephaly during the gestational period of women in Brazil. Methodology: Systematic reviews of intervention research, current publications of clinical investigations were used systematic search strategies in three electronic databases PubMed, SciELO and Google academic. The following keywords were used: Microcephaly, gestation, Zika-virus to perform the search, and 1020 articles were obtained after exclusion, 45 were left and 35 were eligible. The collection period was from 2004 to 2017. Results: Epidemiological data suggest a temporal association between the quantitative increase and the Zika-virus epidemic, especially in Northeast Brazil. It is not consensual to measure the cephalic perimeter curve to be considered. Conclusion: Given this, the application of techniques to accurately diagnose the relationship between causes and effects in the pathogenesis of Zika virus infection in the central nervous system should be prioritized.

The introduction of calistung in AUD focuses on brain optimization of children. The child's brain has a trillion brain cells and trillions of brain-nerve cell connections. Brain nerves. influenced by the number of myelin that awakened at the age of 0-2 years which will determine the ability of abstract thinking, scientific thinking at the formal stage of operations. The backbone and cerebral cortex are the central nervous system for humans. the physical body of the child can be trained through mild exercise. Other parts of the brain in the form of cerebral cortex handle the functions of intellectual and language. Parents or nannies can provide stimulation as needed. The results suggest that children from families with high language intake received higher IQ scores at age three. So is the case with children who get more cognitive stimulation, they are more skilled in language activities. Age of AUD precisely began to learn to read if it has reached the mental age, ie 5-5.5 years.

Accessibility is the possibility of any person to make use of all the benefits of society, including the Internet. As the interfaces are typically graphic, sites can be an obstacle for visually impaired persons to access. For a site to be accessible to blind persons it’s necessary the information contained in the visual resources be reproduced by means of an “equivalent” textual description, capable of transmitting the same information as the visual resources. This study is aimed at identifying and defining usability guidance compliant with accessibility W3C directives that can facilitate the interaction between visually impaired and Internet and still guarantee sites with understandable navigation content. Towards this end an exploratory study was conducted, comprised of a field study and interviews with visually disabled people from Instituto Benjamin Constant, reference center in Brazil for the education of visually impaired persons, in order to get to know these users better.

Adiponectin (ADPN) is a plasma protein secreted by adipose tissue showing pleiotropic effects with anti-diabetic, anti-atherogenic, and anti-inflammatory properties. Initially, it was thought that the main role was only the metabolism control. Later, ADPN receptors were also found in the central nervous system (CNS). In fact, the receptors AdipoR1 and AdipoR2 are expressed in various areas of the brain, including the hypothalamus, hippocampus, and cortex. While AdipoR1 regulates insulin sensitivity through the activation of the AMP-activated protein kinase (AMPK) pathway, AdipoR2 stimulates the neural plasticity through the activation of the peroxisome proliferator-activated receptor alpha (PPARα) pathway that inhibits inflammation and oxidative stress. Overall, based on its central and peripheral actions, ADPN appears to have neuroprotective effects by reducing inflammatory markers, such as C-reactive protein (PCR), interleukin 6 (IL6), and Tumor Necrosis Factor a (TNFa). Conversely, high levels of inflammatory cascade factors appear to inhibit the production of ADPN, suggesting bidirectional modulation. In addition, ADPN appears to have insulin-sensitizing action. It is known that a reduction in insulin signaling is associated with cognitive impairment. Based on this, it is of great interest to investigate the mechanism of restoration of the insulin signal in the brain as an action of ADPN, because it is useful for testing a possible pharmacological treatment for the improvement of cognitive decline. Anyway, if ADPN regulates neuronal functioning and cognitive performances by the glycemic metabolic system remains poorly explored. Moreover, although the mechanism is still unclear, women compared to men have a doubled risk of developing cognitive decline. Several studies have also supported that during the menopausal transition, the estrogen reduction can adversely affect the brain, in particular, verbal memory and verbal fluency. During the postmenopausal period, in obese and insulin-resistant individuals, ADPN serum levels are significantly reduced. Our recent study has evaluated the relationship between plasma ADPN levels and cognitive performances in menopausal women. Thus, the aim of this review is to summarize both the mechanisms and the effects of ADPN in the central nervous system and the relationship between plasma ADPN levels and cognitive performances, also in menopausal women.

Although fax communications pose a problem of accessibility for blind and visually impaired office workers, with centralized readers’ services they could be used to address the wider reading needs of blind and visually impaired people. With this technology, blind persons with fax machines could send unknown print to readers at a centralized readers’ service, who would read facsimiles of the documents over voice phones. This article discusses the specifications for appropriate equipment and protocols and presents the preliminary results of a study of such a system.
