  • Deco, Gustavo; He, Biyu J.; Ponce-Alvarez, Adrián; Hagmann, Patric (Public Library of Science (PLoS), 2015)
    How a stimulus or a task alters the spontaneous dynamics of the brain remains a fundamental open question in neuroscience. One of the most robust hallmarks of task/stimulus-driven brain dynamics is the decrease of variability ...
  • Delgado Kloos, Carlos; Hernández-Leo, Davinia; Asensio-Pérez, Juan I. (Graz University of Technology. Institut für Informationssysteme und Computer Medien (IICM), 2012)

    This paper presents a new registration algorithm, called Temporal Di eomorphic Free Form Deformation (TDFFD), and its application to motion and strain quanti cation from a sequence of 3D ultrasound (US) images. The originality ...
  • Martínez-García, Marina; Insabato, Andrea; Pannunzi, Mario; Pardo-Vazquez, Jose L.; Acuña, Carlos; Deco, Gustavo (Public Library of Science (PLoS), 2015)
    Estimating the difficulty of a decision is a fundamental process to elaborate complex and adaptive behaviour. In this paper, we show that the movement time of behaving monkeys performing a decision-making task is correlated ...
  • Martin, Clara D.; Strijkers, Kristof; Santesteban, Mikel; Escera, Carles; Hartsuiker, Robert J.; Costa, Albert (Frontiers Media, 2013)
    This study asks whether early bilingual speakers who have already developed a language control mechanism to handle two languages control a dominant and a late acquired language in the same way as late bilingual speakers. ...
  • Insabato, Andrea; Dempere-Marco, Laura; Pannunzi, Mario; Deco, Gustavo; Romo, Ranulfo (Public Library of Science (PLoS), 2014)
    Decision making is a process of utmost importance in our daily lives, the study of which has been receiving notable attention for decades. Nevertheless, the neural mechanisms underlying decision making are still not ...

    A new multimodal biometric database designed and acquired within the framework of the European BioSecure Network of Excellence is presented. It is comprised of more than 600 individuals acquired simultaneously in three ...
  • Buehlmann, Andrés; Deco, Gustavo (Society for Neuroscience, 2008)
    Extensive theoretical and experimental work on the neuronal correlates of visual attention raises two hypotheses about the underlying mechanisms. The first hypothesis, named biased competition, originates from experimental ...
  • Singh, Pankai K.; Marzo, Alberto; Coley, Stuart C.; Berti, Guntram; Bijlenga, Philippe; Lawford, Patricia V.; Villa-Uriol, Maria-Cruz; Rufenacht, Daniel A.; McCormack, Keith M.; Frangi Caregnato, Alejandro; Patel, Umang J.; Hose, D. Rodney (Hindawi, 2009)
    Objective: The importance of hemodynamics in the etiopathogenesis of intracranial aneurysms (IAs) is widely accepted. Computational fluid dynamics (CFD) is being used increasingly for hemodynamic predictions. However, ...
  • Deco, Gustavo; Buehlmann, Andrés; Masquelier, Timothée; Hugues, Etienne (Frontiers Media, 2011)
    Rhythmic neural synchronization is found throughout the brain during many different tasks and even at rest. Beyond their underlying mechanisms, the question of their role is still controversial. Modeling can bring insight ...
  • Brunellière, Angèle; Soto-Faraco, Salvador, 1970- (Elsevier, 2013)
    This study investigates the specificity of predictive coding in spoken word comprehension using event-related potentials (ERPs). We measured word-evoked ERPs in Catalan speakers listening to semantically constraining ...
  • Masquelier, Timothée; Albantakis, Larissa; Deco, Gustavo (Frontiers Media, 2011)
    In this review, we describe our recent attempts to model the neural correlates of visual perception with biologically inspired networks of spiking neurons, emphasizing the dynamical aspects. Experimental evidence suggests ...
  • Rubio Ballester, Belén; Nirme, Jens; Duarte Oller, Esther; Cuxart, Ampar; Rodriguez, Susana; Verschure, Paul F. M. J.; Duff, Armin (Biomed central, 2015)
    BACKGROUND: Stroke-induced impairments result from both primary and secondary causes, i.e. damage to the brain and the acquired non-use of the impaired limbs. Indeed, stroke patients often under-utilize their paretic limb ...
  • Hatzidaki, Anna; Baus, Cristina; Costa, Albert (Frontiers Media, 2015)
    The present study examined whether processing words with affective connotations in a listener's native language may be modulated by accented speech. To address this question, we used the Event Related Potential (ERP) ...
  • Larrabide, Ignacio, 1978-; Villa-Uriol, Maria-Cruz; Cardenes, Rubén; Pozo Soler, José Ma. (José María); Macho, Juan M.; San Román, Luis; Blasco, Jordi; Vivas, Elio; Marzo, Alberto; Hose, D. Rodney; Frangi Caregnato, Alejandro (American Association of Physicists in Medicine (AAPM), 2011)
    Morphological descriptors are practical and essential biomarkers for diagnosis and treatment selection for intracranial aneurysm management according to the current guidelines in use. Nevertheless, relatively little work ...
  • Villa-Uriol, Maria-Cruz; Larrabide, Ignacio, 1978-; Pozo Soler, José Ma. (José María); Kim, Minsuok; Camara, Oscar; De Craene, Mathieu; Zhang, Chong; Geers, Arjan; Morales, Hernán G.; Bogunovic, Hrvoje; Cardenes, Rubén; Frangi Caregnato, Alejandro (Royal Society, 2010)
    In the last few years, some of the visionary concepts behind the virtual physiological human began to be demonstrated on various clinical domains, showing great promise for improving healthcare management. In the current ...

    Carrier sense multiple access with enhanced collision avoidance (CSMA/ECA) is a distributed MAC protocol that allows collisionfree access to the medium in WLANs. The only difference between CSMA/ECA and the well-known ...
  • Parés, Narcís, 1966-; Parés, Roc, 1968- (MIT Press, 2006)
    After analyzing how VR experiences are modeled within human computer interaction (CHI) we have found there is a deep theoretical gap. Similarly to how the scientific community has defined CHI models for multimedia applications, ...
