  • Deco, Gustavo; Hugues, Etienne (Public Library of Science, 2012)
    Recent neurophysiological experiments have demonstrated a remarkable effect of attention on the underlying neural/nactivity that suggests for the first time that information encoding is indeed actively influenced by ...
  • Vazquez-Vilar, Gonzalo; Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Two alternative exact characterizations of the minimum error probability of Bayesian M-ary hypothesis testing are derived. The first expression corresponds to the error probability of an induced binary hypothesis test and ...
  • Al-Nahari, Azzam; Geraci, Giovanni; Al-Jamali, Mukarram; Hossam Ahmed, Mohamed; Yang, Nan (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    In this paper, we consider multiple-input single-output multi-eavesdropper cognitive radio networks (MISOME-CRNs), where a secondary user (SU) aims to transmit confidential information to a legitimate SU receiver in the ...
  • Biau, Emmanuel, 1985-; Soto-Faraco, Salvador, 1970- (Elsevier, 2013)
    Spontaneous beat gestures are an integral part of the paralinguistic context during face-to-face conversations. Here we investigated the time course of beat-speech integration in speech perception by measuring ERPs evoked ...
  • Rosales, Andrea; Sayago Barrantes, Sergio; Blat, Josep (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Three playful wearable accessories incorporate design principles that promote individuality, natural interaction, ubiquity, and intimacy to encourage spontaneous open-ended social interaction in school-age children. The ...
  • Castro Santa, Juana; Exadaktylos, Filippos; Soto-Faraco, Salvador, 1970- (Nature Publishing Group, 2018)
    Is collaboration the fast choice for humans? Past studies proposed that cooperation is a behavioural default, based on Response Times (RT) findings. Here we contend that the individual’s reckoning of the immediate social ...
  • Hoogendoorn, Corné; Sukno, Federico Mateo; Ordás, Sebastián; Frangi Caregnato, Alejandro (Springer, 2009)
    In this work we describe the usage of bilinear statistical models as a means of factoring the shape variability into two components attributed to inter-subject variation and to the intrinsic dynamics of the human heart. ...
  • Burgaleta Díaz, Miguel, 1981-; Sanjuán, Ana; Ventura Campos, Noelia; Sebastián Gallés, Núria; Ávila, César (Elsevier, 2016)
    Naturally acquiring a language shapes the human brain through a long-lasting learning and practice process. This is supported by previous studies showing that managing more than one language from early childhood has an ...
  • Rodríguez Pujadas, Aina; Sanjuán, Ana; Ventura Campos, Noelia; Román, Patricia; Martin, Clara D.; Barceló-Arroyo, Francisco; Costa, Albert, 1970-; Ávila, César (Public Library of Science, 2013)
    We tested the hypothesis that early bilinguals use language-control brain areas more than monolinguals when performing/nnon-linguistic executive control tasks. We do so by exploring the brain activity of early bilinguals ...
  • Costalat, Vincent; Sánchez, Mathieu; Ambard, Dominique; Thines, Laurent; Lonjon, Nicolas; Nicoud, Franck; Brunel, Hervé; Lejeune, Jean Paul; Dufour, Henry; Bouillot, Pablo; Lhaldky, J. P.; Kouri, K.; Segnarbieux, François; Mourage, Claude Alain; Lobostein, Kyriakos; Villa-Uriol, Maria-Cruz; Zhang, Chong; Frangi Caregnato, Alejandro; Mercier, Grégoire; Bonafé, Alain; Sarry, L.; Jourdan, Franck (Elsevier, 2011)
    Background and purpose: Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength ...
  • Andrzejak, Ralph Gregor; Kraskov, Alexander; Stögbauer, Harald; Mormann, Florian; Kreuz, Thomas (American Physical Society, 2003)
    The concept of surrogates allows testing results from time series analysis against specified null hypotheses. In application to bivariate model dynamics we here compare different types of surrogates, each designed to test ...
  • Nakagawa, Tristan T.; Jirsa, Viktor K.; Spiegler, Andreas; McIntosh, Anthony R.; Deco, Gustavo (Elsevier, 2013)
    With the increasing availability of advanced imaging technologies, we are/nentering a new era of neuroscience. Detailed descriptions of the complex brain/nnetwork enable us to map out a structural connectome, characterize ...
  • Dalmazzo, David; Ramírez, Rafael,1966- (Frontiers, 2019)
    Gestures in music are of paramount importance partly because they are directly linked to musicians' sound and expressiveness. At the same time, current motion capture technologies are capable of detecting body motion/gestures ...
  • Deco, Gustavo; Cruzat, Josephine; Kringelbach, Morten L. (Nature Research, 2019)
    A key unresolved problem in neuroscience is to determine the relevant timescale for understanding spatiotemporal dynamics across the whole brain. While resting state fMRI reveals networks at an ultraslow timescale (below ...
  • Kringelbach, Morten L.; Deco, Gustavo (Elsevier, 2020)
    Within the field of computational neuroscience there are great expectations of finding new ways to rebalance the complex dynamic system of the human brain through controlled pharmacological or electromagnetic perturbation. ...
  • Vidal, Vincent; Geffner, Héctor (Elsevier, 2006)
    A key feature of modern optimal planners such as graphplan and blackbox is their ability to prune large parts of the search space. Previous Partial Order Causal Link (POCL) planners provide an alternative branching scheme ...
  • Padilla, Nelly; Saenger, Victor M.; van Hartevelt, Tim J.; Fernandes, Henrique M.; Lennartsson, Finn; Andersson, Jesper L. R.; Kringelbach, Morten L.; Deco, Gustavo; Åden, Ulrika (Oxford University Press, 2019)
    The brain operates at a critical point that is balanced between order and disorder. Even during rest, unstable periods of random behavior are interspersed with stable periods of balanced activity patterns that support ...
  • Hyafil, Alexandre; Moreno Bote, Rubén (eLife, 2017)
    Possible options in a decision often organize as a hierarchy of subdecisions. A recent study concluded that perceptual processes in primates mimic this hierarchical structure and perform subdecisions in parallel. We argue ...
  • Sadat Schaffai, Jasmin, 1982-; Martin, Clara D.; Magnuson, James S.; Alario, F.-Xavier (François -Xavier); Costa, Albert, 1970- (Wiley, 2016)
    Bilinguals have been shown to perform worse than monolinguals in a variety of verbal tasks. This study investigated this bilingual verbal cost in a large‐scale picture‐naming study conducted in Spanish. We explored how ...
  • Lluch Alvarez, Èric; De Craene, Mathieu; Bijnens, Bart; Sermesant, Maxime; Noailly, Jérôme; Camara, Oscar; Morales, Hernán G. (Springer, 2019)
    Cardiac modeling has recently emerged as a promising tool to study pathophysiology mechanisms and to predict treatment outcomes for personalized clinical decision support. Nevertheless, achieving convergence under large ...
