Pattern changes of EEG oscillations and BOLD signals associated with temporal lobe epilepsy as revealed by a working memory task
(Biomed Central LtdLondonInglaterra, 2014)
Effects of risk genes on BOLD activation in presymptomatic carriers of familial alzheimer's disease mutations during a novelty encoding task
(2011)
Prior functional magnetic resonance imaging (fMRI) studies have found increased activity-related blood oxygen level-dependent (BOLD) signal in cognitively normal persons at genetic risk for Alzheimer's disease (AD). This ...
Effects of risk genes on BOLD activation in presymptomatic carriers of familial alzheimer's disease mutations during a novelty encoding task
(2011)
Prior functional magnetic resonance imaging (fMRI) studies have found increased activity-related blood oxygen level-dependent (BOLD) signal in cognitively normal persons at genetic risk for Alzheimer's disease (AD). This ...
Wavelet correlation between subjects: A time-scale data driven analysis for brain mapping using fMRI
(ELSEVIER SCIENCE BV, 2011)
Functional magnetic resonance imaging (fMRI) based on BOLD signal has been used to indirectly measure the local neural activity induced by cognitive tasks or stimulation. Most fMRI data analysis is carried out using the ...
Glutamate and the neural basis of the subjective effects of ketamine
(AMER MEDICAL ASSOC, 2008)
Context: Ketamine evokes psychosislike symptoms, and its primary action is to impair N-methyl-D-aspartate glutamate receptor neurotransmission, but it also induces secondary increases in glutamate release. Objectives: To ...
Engagement of multifocal neural circuits during recall of autobiographical happy events
(Associação Brasileira de Divulgação Científica, 2008)
Happy emotional states have not been extensively explored in functional magnetic resonance imaging studies using autobiographic recall paradigms. We investigated the brain circuitry engaged during induction of happiness ...
Establishing an acquisition and processing protocol for resting state networks with a 1.5 T scanner: A case series in a middle-income country
(Wolters Kluwer Health, Inc.Estados Unidos, 2020-06)
Objective: The aim of this study was to characterize the capability of detection of the resting state networks (RSNs) with functional
magnetic resonance imaging (fMRI) in healthy subjects using a 1.5T scanner in a ...
Pipeline for the Classification of Subjects with Neurodegenerative Diseases Based on Biomedical Signal Processing and Machine Learning Techniques
(Grupo de Investigación en Bioinstrumentación e Ingeniería Clínica (GIBIC)Medellín, 2022)
