Efeito da variação de frequência e duração do estímulo no registro do P300 e MMN
(Universidade Estadual Paulista (Unesp), 2014-02-13)
Introduction: The Cognitive Potential (CP) test refers to the picking up of specific electric events that evoke sensory responses of the brain from external stimuli. CPs are composed of N1, P2, N2, P3 and MMN components, ...
Aquisição simultânea de eletroencefalografia e ressonância magnética funcional para investigação da plasticidade neural
(Universidade Federal de Minas GeraisUFMG, 2010-08-20)
This thesis presents a study on neuronal plasticity based on simultaneous recording of electroencephalography (EEG) and functional magnetic resonance (fMRI). There is an accumulating body of evidence indicating that neuronal ...
Caracterização eletrofisiológica das oscilações delta e teta do hipocampo dorsal de ratos durante locomoção em esteira
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2020-06-09)
The hippocampal theta rhythm (6-10 Hz) has been extensively studied since the 1950’s. These
researches have shown that the theta rhythm is involved with cognitive functions, sensorymotor integration, paradoxical sleep and ...

Neuroimmune interactions in stress
(Basel, 2010)
Stress has long been recognized as a putative modulator of immunity. Several clinical and experimental reports point to a role of physical and psychological stressors on progression or resistance to disease. Nonetheless, ...
Ontogenetic changes in cranial vault thickness in a modern sample of Homo sapiens
(Wiley Periodicals Inc, 2014-12)
Objectives This work assesses cranial vault thickness (CVT) ontogenetic changes using a computed tomography database to register thickness across multiple regions. Methods Vault images of 143 individuals from 0 to 31 years ...
Instrumentos na avaliação da fragilidade em idosos comunitários: uma revisão de literatura
(Universidade Federal de Minas GeraisUFMG, 2015-12-05)
INTRODUCTION: There is no consensus regarding the evaluation of frailty. Because of this, the choice of instrument depends on the definition referred to, as well as the population variation. (19,20) The objective of this ...
Computational strategies to characterize topological properties of pathologically altered functional brain networks
(Universidad Nacional de ColombiaBogotá - Ingeniería - Doctorado en Ingeniería - Sistemas y ComputaciónFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022)
Consciousness alterations, including disorders of consciousness (DOC), propose a defiant scenario from the prognosis and diagnosis perspectives. Brain resting-state functional imaging mitigates this challenge, offering ...
Global and regional effects of potentially modifiable risk factors associated with acute stroke in 32 countries (INTERSTROKE): a case-control study
(Elsevier, 2016)
BACKGROUND: Stroke is a leading cause of death and disability, especially in low-income and middle-income countries. We sought to quantify the importance of potentially modifiable risk factors for stroke in different regions ...
