RESUMO
There are considerable gaps in our understanding of the relationship between human brain activity measured at different temporal and spatial scales. Here, electrocorticography (ECoG) measures were used to predict functional MRI changes in the sensorimotor cortex in two brain states: at rest and during motor performance. The specificity of this relationship to spatial co-localisation of the two signals was also investigated. We acquired simultaneous ECoG-fMRI in the sensorimotor cortex of three patients with epilepsy. During motor activity, high gamma power was the only frequency band where the electrophysiological response was co-localised with fMRI measures across all subjects. The best model of fMRI changes across states was its principal components, a parsimonious description of the entire ECoG spectrogram. This model performed much better than any others that were based either on the classical frequency bands or on summary measures of cross-spectral changes. The region-specific fMRI signal is reflected in spatially and spectrally distributed EEG activity.
RESUMO
RESUMO: A área de investigação do turismo acessível (TA) apresenta uma tendência de crescimento. Contudo, a maioria dos estudos foca-se na acessibilidade física, havendo poucos que analisem as atitudes dos estudantes e profissionais desse setor relativamente às pessoas com deficiência (PcD). Assim sendo, esta revisão tem como objetivo analisar os trabalhos efetuados em outras áreas científicas sobre as atitudes relativamente às PcD. Pretende-se mapear metodologias, instrumentos de medição e principais variáveis e fatores associados às atitudes, para promover a sua inclusão na sociedade. Realizaram-se pesquisas na Scopus, tendo-se obtido 492 registos. Destes, foram selecionados 96 artigos para análise. Os resultados evidenciam que a avaliação das atitudes relativamente às PcD é uma temática de grande relevância em várias áreas científicas. Os estudos utilizam diversos instrumentos para medir essas atitudes. As experiências anteriores, qualidade e frequência do contato com PcD e conhecimento acerca da deficiência têm influência nas atitudes. Contudo, os resultados divergem na influência do perfil sociodemográfico nas atitudes face às PcD. Existe tendência para o recurso a metodologias quantitativas utilizando, como instrumento de recolha de dados, o questionário. O artigo termina identificando áreas de investigação relevantes para o aumento do conhecimento dos fatores que influenciam essas atitudes e, consequentemente, para o desenvolvimento do TA.
ABSTRACT: The investigation area of accessible tourism (AT) has a growing trend. However, most studies focus on physical accessibility, and only a few analyse the attitudes of students and professionals in this sector towards people with disabilities (PwD). This review aims to analyse the work carried out in other scientific areas on attitudes towards PwD. It is intended to map methodologies, measurement instruments and main variables and factors related with attitudes, to promote their inclusion in society. Research was carried out at Scopus and 492 records were obtained. Of these, 96 articles were selected for analysis. Results show that the assessment of attitudes towards PwD is a topic of great relevance in several scientific areas. Studies use several instruments to measure these attitudes. Previous experiences, quality, and frequency of contact with PwD and knowledge about disability have an influence on attitudes. However, results differ in the influence of the sociodemographic profile on attitudes towards PwD. There is a trend towards the use of quantitative methodologies, using the questionnaire as a tool for data collection. The article ends by identifying areas of research relevant to the increasing knowledge of the factors that influence these attitudes and, consequently, to the development of AT.
