    Recent research indicates that anodal transcranial direct current stimulation (tDCS) applied over the frontal eye field (FEF) can be used to improve saccadic eye movement control in healthy young adults. The current research set out to replicate these findings using a clinically practical protocol, to test whether tDCS applied over the dorsolateral prefrontal cortex (DLPFC) might also afford benefits, and to determine whether benefits extend to older adults, who are known to suffer from saccadic eye movement control deficits. Twenty young and 10 older adults completed two active (FEF and DLPFC) and one sham stimulation session. In an effort to aid clinical translation, the method of positioning the electrodes entailed simple measurements only. No improvements in saccadic performance emerged following anodal tDCS applied over the FEF or DLPFC relative to the sham condition in either age group. In addition, saccadic performance contralateral to the active electrodes showed no evidence of benefits over ipsilateral performance. These negative results question whether the protocol utilized can be applied effectively using only simple measurements to localize the relevant frontal subregion. Future efforts can consider adjusting the tDCS montage that might yield more promising results to improve saccadic eye movement control in older adults

    Famous Faces Demand Attention Due to Reduced Inhibitory Processing

    People have particular difficulty ignoring distractors that depict faces. This phenomenon has been attributed to the high level of biological significance that faces carry. The current study aimed to elucidate the mechanism by which faces gain processing priority. We used a focused attention paradigm that tracks the influence of a distractor over time and provides a measure of inhibitory processing. Upright famous faces served as test stimuli and inverted versions of the faces as well as upright non-face objects served as control stimuli. The results revealed that although all of the stimuli elicited similar levels of distraction, only inverted distractor faces and non-face objects elicited inhibitory effects. The lack of inhibitory effects for upright famous faces provides novel evidence that reduced inhibitory processing underlies the mandatory nature of face processing

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este trabalho pretende apresentar as formas de percepção de corpo e honra na sociedade paulistana entre os anos de 1890 e 1920, por meio de discursos presentes em processos judiciais movidos por crimes sexuais, obras de direito e os códigos penais promulgados no Brasil. No período compreendido, a cidade passava por muitas transformações, que iam desde a reformulação urbana da cidade até a transformação nos regimes de trabalho, pautadas por uma nova ordem econômica de cunho capitalista. Através das fontes históricas selecionadas, pretendo mostrar as formas de interação entre as camadas privilegiadas ? que, em geral, possuíam as instituições de controle (como o sistema jurídico) e buscavam a formação de um tipo disciplinado de trabalhador, pautando-se em valores como honra, moralidade, família e trabalho ? e as camadas pobres, que procuravam ajustar-se a esses valores, ressignificando-os, entretanto, para as suas próprias experiências comunitárias, demonstrando suas próprias noções de honra, tristeza, sofrimento físico e psicológico.Abstract : This work intends to present the forms of body´s and honor´s perception of the São Paulo´s city between 1890 and 1920, through discourses present in sexual criminal judicial processes, legal books and penal codes promulgated in Brazil. In such historical period, the city of São Paulo undergone many transformations, from urban reconstruction until transformations of work regimes, all of them characterized by the emergent capitalist economic order. Through the selected historical sources, I´ll try to show the forms of interaction between the privileged social strata ? which in general dominated the institutions of social control (e.g. the juridical system) and sought the formation of disciplined type of worker, having as parameter values such as honor, morality, family and work ? and the poorest social strata, which sought to ajust themselves to such values, but re-signifying them to their proper comunitarian experiences, expressing their proper notions of honor, sadness, physical and psychological suffering

    EDUCAÇÃO FÍSICA ESCOLAR E EDUCAÇÃO SOBRE DROGAS: CAMPO DE DESENVOLVIMENTO DAS HABILIDADES SOCIAIS

    Este trabalho tem como objetivo analisar os resultados de um programa denominado Educação Sobre Drogas e Habilidades Sociais, desenvolvido em uma escola no interior do estado do Espírito Santo, Brasil, na disciplina de Educação Física. Participaram 145 estudantes do ensino fundamental e ensino médio com idades entre 11 e 17 anos. Foram 10 encontros temáticos sobre álcool e outras drogas e habilidades sociais com avaliação ao final a partir do Google Formulários. O programa foi bem aceito pelos participantes e contribuiu com novos conhecimentos sobre o tema drogas. Conclui-se que as habilidades sociais podem se apresentar como um dos recursos importantes para a educação sobre drogas ao permitir que outras áreas da vida dos envolvidos sejam problematizadas.

    The influence of different scan resolutions on the detection of proximal caries lesions

    Get PDF
    This study was conducted to evaluate the effect of different spatial resolutions of a photostimulable phosphor plate (PSP) radiography system on the detection of proximal caries lesions. Materials and Methods: Forty-five extracted human permanent teeth were radiographed using a PSP system (VistaScan Perio Plus) and scanned at the 4 resolutions (10 lp/mm, 20 lp/mm, 25 lp/mm, and 40 lp/mm) available in the system. Three independent examiners scored the images for the presence and absence of proximal caries lesions using a 5-point scale. The presence or absence of caries was confirmed by histological sections of the examined teeth (defined as the gold standard). Intra-and inter-observer reproducibility was calculated by the weighted kappa test. One-way analysis of variance with the post hoc Tukey test was used to compare the area under the receiver operating characteristic curve for the classifications made with each resolution. Results: For the detection of enamel lesions, the spatial resolution of 10 lp/mm was significantly superior to the other resolutions. However, the spatial resolution did not affect the detection of caries lesions in dentin (P>0.05). Conclusion: Spatial resolution may influence the accuracy of the detection of incipient caries lesions in radiographs with PSP plates. Images with low spatial resolution seem to be more appropriate for this purpose49297102sem informaçãosem informaçã
