  • 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 ...
  • Tauste Campo, Adrià; Martínez-García, Marina; Nácher, Verónica; Luna, Rogelio; Romo, Ranulfo; Deco, Gustavo (National Academy of Sciences, 2015)
    Neural correlations during a cognitive task are central to study brain information processing and computation. However, they have been poorly analyzed due to the difficulty of recording simultaneous single neurons during ...
  • Delgado Kloos, Carlos; Hernández Leo, Davinia; Asensio-Pérez, Juan I. (Graz University of Technology. Institut für Informationssysteme und Computer Medien (IICM), 2012)
  • De Craene, Mathieu; Piella Fenoy, Gemma; Camara, Oscar; Duchateau, Nicolas Guillem; Silva, Etelvino; Doltra, Adelina; D'hooge, Jan; Brugada, Josep; Sitges, Marta; Frangi Caregnato, Alejandro (Elsevier, 2011)
    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 ...
  • Urbano, Julián (Springer, 2016)
    The number of topics that a test collection contains has a direct impact on how well the evaluation results reflect the true performance of systems. However, large collections can be prohibitively expensive, so researchers ...
  • ten Oever, Sanne; Romei, Vincenzo; van Atteveldt, Nienke; Soto-Faraco, Salvador, 1970-; Murray, Micah M.; Matusz, Pawel J. (Springer, 2016)
    Our understanding of how perception operates in real-world environments has been substantially advanced by studying both multisensory processes and “top-down” control processes influencing sensory processing via activity ...
  • Serra, Xavier (International Musicological Society, 2017)
    From most musical cultures there are digital traces, digital artifacts, that can be processed and studied computationally, and this has been the focus of computational musicology already for several decades. This type ...
  • 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. ...
  • Ayneto, Alba; Sebastián Gallés, Núria (Wiley, 2016)
    Bilingual infants show an extended period of looking at the mouth of talking faces, which provides them with additional articulatory cues that can be used to boost the challenging situation of learning two languages (Pons, ...
  • Insabato, Andrea; Dempere-Marco, Laura; Pannunzi, Mario; Deco, Gustavo; Romo, Ranulfo (Public Library of Science (PLoS), 2014)
    Decision making is a process of utmost/nimportance in our daily lives, the study of which has/nbeen receiving notable attention for decades. Nevertheless,/nthe neural mechanisms underlying decision making/nare still not ...
  • Soto-Faraco, Salvador, 1970-; Brunellière, Angèle (Wiley, 2015)
    This study addresses how top-down predictions driven by phonological and semantic information interact on spokenword comprehension. To do so, we measured event-related potentials to words embedded in sentences that varied ...
  • Deco, Gustavo; Van Hartevelt, Tim J.; Fernandes, Henrique M.; Stevner, Angus B. A.; Kringelbach, Morten L. (Elsevier, 2017)
    In order to promote survival through flexible cognition and goal-directed behaviour, the brain has to optimize segregation and integration of information into coherent, distributed dynamical states. Certain organizational ...
  • Ortega-Garcia, Javier; Fierrez, Julian; Alonso-Fernández, Fernando; Galbally, Javier; Freire, Manuel R.; González-Rodríguez, Joaquín; García-Mateo, Carmen; Alba-Castro, José-Luís; González-Agulla, Elisardo; Otero-Muras, Enrique; García-Salicetti, Sonia; Allano, Lorene; Ly-Van, Bao; Dorizzi, Bernadette; Kittler, Josef; Bourlai, Thirimachos; Poh, Norman; Deravi, Farzin; Ng, Ming W.R.; Fairhurst, Michael; Hennebert, Jean; Humm, Andreas; Tistarelli, Massimo; Brodo, Linda; Richiardi, Jonas; Drygajlo, Andrzej; Ganster, Harald; Sukno, Federico M.; Pavani, Sri-Kaushik; Frangi Caregnato, Alejandro; Akarun, Lale; Savran, Arman (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    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 ...
  • Kringelbach, Morten L.; McIntosh, Anthony R.; Ritter, Petra; Jirsa, Viktor K.; Deco, Gustavo (Elsevier, 2015)
    Slowness of thought is not necessarily a handicap but could be a signature of optimal brain function. Emerging evidence shows that neuroanatomical and dynamical constraints of the human brain shape its functionality in ...
  • 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./nComputational 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 ...
