Integrated photonic circuits based on plasmonic modes in microstructured optical fibers
(Medellín - Ciencias - Doctorado en Ciencias - FísicaEscuela de físicaUniversidad Nacional de Colombia - Sede Medellín, 2020-11-06)
This thesis considers the phenomena associated with plasmon modes excited in MOFs, with a particular interest in higher-order plasmon modes and their coupling with propagation modes of the MOF. These multiple couplings, ...
Análisis de Imágenes de Resonancia Magnética por difusión de adolescentes con autismo.
(Universidad de Concepción.Facultad de Ingeniería.Departamento de Ingeniería Eléctrica.Concepción., 2023)
El uso de neuroimágenes ha experimentado un crecimiento significativo en las últimas décadas, brindando una amplia gama de técnicas e investigaciones que respaldan el estudio, diagnóstico y seguimiento de enfermedades y ...
Automatic Dti-based Parcellation Of The Corpus Callosum Through The Watershed Transform
(Sociedade Brasileira de Engenharia Biomedica, 2014)
DTI voxelwise analysis did not differentiate older depressed patients from older subjects without depression
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Introduction: Neuroimaging has been widely used in studies to investigate depression in the elderly because it is a noninvasive technique, and it allows the detection of structural and functional brain alterations. Fractional ...
Region-specific changes in Mus musculus brain size and cell composition under chronic nutrient restriction
(Company of Biologists, 2019-09)
Nutrition is one of the most influential environmental factors affecting the development of different tissues and organs. It is suggested that under nutrient restriction the growth of the brain is spared as a result of the ...
A influência de estímulos visuais na modificação de padrões neurais do comportamento motor dançado: uma perspectiva neurofisiológica
(Universidade Federal de Minas GeraisBrasilICB - INSTITUTO DE CIÊNCIAS BIOLOGICASPrograma de Pós-Graduação em NeurociênciasUFMG, 2020-07-21)
Dance has been a recurrent object, even if timidly, of study in Neurosciences. Because of the extreme complexity of tests with danced movement, little is known about the neurophysiological aspects involved in such activity. ...
Conectividade estrutural cerebral, alfabetização e desempenho cognitivo em uma amostra de idosos da comunidade: estudo por análise de ressonância magnética utilizando imagens por tensor de difusão
(Universidade Federal de Minas GeraisUFMG, 2015-12-09)
The association between white matter (WM) integrity, cognitive perfomance and cognitive reserve in elderly subjects is a challenging field of research. We applied magnetic resonance (MR) difusion tensor imaging (DTI) to ...
