  • Acute sleep deprivation induces a local brain transfer information increase in the frontal cortex in a widespread decrease context 

    Alonso López, Joan Francesc; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Alcalá Álvarez, Marta; Antonijoan, Rosa Maria; Giménez Badia, Sandra (2016-04-01)
    Article
    Accés obert
    Sleep deprivation (SD) has adverse effects on mental and physical health, affecting the cognitive abilities and emotional states. Specifically, cognitive functions and alertness are known to decrease after SD. The aim of ...
  • Evaluation of multiple comparison correction procedures in drug assessment studies using LORETA maps 

    Alonso López, Joan Francesc; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Rojas Martínez, Mónica; Riba Serrano, Jordi; Barbanoj, Manuel José (2015-10-01)
    Article
    Accés obert
    The identification of the brain regions involved in the neuropharmacological action is a potential procedure for drug development. These regions are commonly determined by the voxels showing significant statistical differences ...
  • Monitoring sleep depth: analysis of bispectral index (BIS) based on polysomnographic recordings and sleep deprivation 

    Giménez Badia, Sandra; Romero Lafuente, Sergio; Alonso López, Joan Francesc; Mañanas Villanueva, Miguel Ángel; Pujol, Anna; Baxarias, Pilar; Antonijoan Arbós, Rosa Maria (2015-11-14)

    © 2015 Springer Science+Business Media Dordrecht The assessment and management of sleep are increasingly recommended in the clinical practice. Polysomnography (PSG) is considered the gold standard test to monitor sleep ...
  • Auditory P3a and P3b neural generators in schizophrenia: An adaptive sLORETA P300 localization approach 

    Bachiller, Alejandro; Romero Lafuente, Sergio; Molina, Vicente; Alonso López, Joan Francesc; Mañanas Villanueva, Miguel Ángel; Poza Crespo, Jesús; Hornero Sánchez, Roberto (2015-12)
    Article
    Accés restringit per política de l'editorial
    The present study investigates the neural substrates underlying cognitive processing in schizophrenia (Sz) patients. To this end, an auditory 3-stimulus oddball paradigm was used to identify P3a and P3b components, elicited ...
  • Robust fault diagnosis of proton exchange membrane fuel cells using a Takagi-Sugeno interval observer approach 

    Rotondo, Damiano; Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2016-01-07)
    Article
    Accés restringit per política de l'editorial
    In this paper, the problem of robust fault diagnosis of proton exchange membrane (PEM) fuel cells is addressed by introducing the Takagi-Sugeno (TS) interval observers that consider uncertainty in a bounded context, adapting ...
  • Non-linear set-membership identification approach based on the Bayesian framework 

    Fernández Canti, Rosa M.; Tornil Sin, Sebastián; Blesa Izquierdo, Joaquim; Puig Cayuela, Vicenç (2015-06-06)
    Article
    Accés obert
    This study deals with the problem of set-membership identification of non-linear-in-the-parameters models. To solve this problem, this study illustrates how the Bayesian approach can be used to determine the feasible ...
  • Fault detection and isolation for a wind turbine benchmark using a mixed Bayesian/set-membership approach 

    Fernández Canti, Rosa M.; Blesa Izquierdo, Joaquim; Tornil Sin, Sebastián; Puig Cayuela, Vicenç (2015-10-30)
    Article
    Accés obert
    This paper addresses the problem of fault detection and isolation of wind turbines using a mixed Bayesian/Set-membership approach. Modeling errors are assumed to be unknown but bounded, following the set-membership approach. ...
  • Neurophysiological evidence of compensatory brain mechanisms in early-stage multiple sclerosis 

    Lopez Gongora, Mariana; Escartín, José Antonio; Martinez Horta, Saul; Fernandez De Bobadilla, Ramon; Querol, Luis; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Riba Serrano, Jordi (2015-08-31)
    Article
    Accés obert
    Multiple sclerosis (MS) is a chronic central nervous system disorder characterized by white matter inflammation, demyelination and neurodegeneration. Although cognitive dysfunction is a common manifestation, it may go ...
  • Serotonergic psychedelics temporarily modify information transfer in humans 

    Alonso López, Joan Francesc; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Riba Serrano, Jordi (2015-06-01)
    Article
    Accés obert
    Background: Psychedelics induce intense modifications in the sensorium, the sense of "self," and the experience of reality. Despite advances in our understanding of the molecular and cellular level mechanisms of these ...
  • Automatic BSS-based filtering of metallic interference in MEG recordings: definition and validation using simulated signals 

    Migliorelli Falcone, Carolina Mercedes; Alonso López, Joan Francesc; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Nowak, Rafal; Russi Tintoré, Antonio (2015-05-27)
    Article
    Accés obert
    Objective. One of the principal drawbacks of magnetoencephalography (MEG) is its high sensitivity to metallic artifacts, which come from implanted intracranial electrodes and dental ferromagnetic prosthesis and produce a ...
