Fernández, Alberto ; Zuluaga Arias, Pilar ; Abásolo, Daniel ; Gómez, Carlos ; Serra González, Anahí María ; Méndez, María Andreína ; Hornero, Roberto | Elsevier | 2012-11Objective Considering the increasing use of complexity estimates in neuropsychiatric populations, a normative study is critical to define the ‘normal’ behaviour of brain oscillatory complexity across the life span. Method This study examines ch[...]texto impreso
Méndez, María Andreína ; Zuluaga Arias, Pilar ; Hornero, Roberto ; Gómez, Carlos ; Escudero, Javier ; Rodríguez Palancas, Alfonso ; Ortiz, Tomás ; Fernández, Alberto | SAGE | 2012-05Magnetoencephalography (MEG) allows the real-time recording of neural activity and oscillatory activity in distributed neural networks. We applied a non-linear complexity analysis to resting-state neural activity as measured using whole-head MEG[...]texto impreso
Fernández, Alberto ; Hornero, Roberto ; Gómez, Carlos ; Turrero, Agustín ; Gil Gregorio, Pedro ; Matías Santos, Juan ; Ortiz, Tomás | Wolters Kluwer Health | 2010-04Nonlinear analyses have shown that Alzheimer disease (AD) patients' brain activity is characterized by a reduced complexity and connectivity. The aim of this study is to define complexity patterns of mild cognitive impairment (MCI) patients. Who[...]texto impreso
Introduction. Test of Everyday Attention for Children (TEA-Ch) has been validated in different countries demonstrating that it is an instrument with a correct balance between reliability and duration. Given the shortage of trustworthy instrument[...]texto impreso
Fernández, Alberto ; de Sola, Rafael G. ; Amo, Carlos ; Turrero, Agustín ; Zuluaga Arias, Pilar ; Maestú, Fernando ; Campo, Pablo ; Ortiz, Tomás | American Clinical Neurophysiology Society | 2004-07Conventional visual analysis and dipole density analysis of magnetoencephalographic data for both spike and low-frequency magnetic activity were compared for presurgical evaluation in temporal lobe epilepsy (TLE) in a sample of 26 drug-resistant[...]texto impreso
Fernández, Alberto ; Turrero, Agustín ; Zuluaga Arias, Pilar ; Gil, Pedro ; Maestú, Fernando ; Campo, Pablo ; Ortiz, Tomás | American Medical Association | 2006-03Background: Subjects with mild cognitive impairment (MCI) are at a higher risk of experiencing Alzheimer disease (AD). Magnetoencephalographic temporoparietal dipole densities of low-frequency activity are good predictors of individuals' cogniti[...]texto impreso
Fernández, Alberto ; Turrero, Agustín ; Zuluaga Arias, Pilar ; Gil Gregorio, Pedro ; Pozo, Francisco del ; Maestú, Fernando ; Moratti, Stephan | IOS Press | 2013New diagnostic criteria for Alzheimer's disease (AD) stress the role of in vivo biomarkers. Neurophysiological markers are usually not considered as such criteria, although theoretical and practical reasons would justify them. In order to assess[...]
