  • Alsius, Agnès; Soto-Faraco, Salvador, 1970- (Springer, 2011)
    A critical question in multisensory processing is how the constant information flow that arrives to our different senses is organized in coherent representations. Some authors claim that pre-attentive detection of inter-sensory ...
  • Ikumi, Nara; Soto-Faraco, Salvador, 1970- (Public Library of Science (PLoS), 2014)
    Temporal recalibration of cross-modal synchrony has been proposed as a mechanism to compensate for timing differences between sensory modalities. However, far from the rich complexity of everyday life sensory environments, ...
  • Hernández Leo, Davinia; Louys, Amélie; Schoonenboom, Judith; Pérez Sanagustín, Maria del Mar; Lemmers, Ruud (International Forum of Educational Technology & Society, 2009)
    This paper describes a pilot study centred on the technology-enhanced self-development of competences in lifelong learning education carried out in the challenging context of the Association of Participants Àgora. The pilot ...
  • Angelosante, Daniele; Biglieri, Ezio; Lops, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Wireless “MIMO” systems, employing multiple transmit and receive antennas, promise a significant increase of channel capacity, while orthogonal frequency-division multiplexing (OFDM) is attracting a good deal of attention ...
  • Amiri Nezhad, Maryam; Guerrero Zapata, Manel; Bellalta, Boris; Cerdà Alabern, Llorenç (SpringerOpen, 2014)
    In the context of wireless network simulation, many simulators are capable of evaluating the performance of single-channel network protocols, but they need many modifications to be able to simulate multi-radio multi-channel ...
  • Abolafia, Juan M.; Martínez-García, Marina; Deco, Gustavo; Sanchez-Vives, Maria V (Frontiers Media, 2011)
    In this study, we recorded single unit activity from rat auditory cortex while the animals performed an interval-discrimination task. The animals had to decide whether two auditory stimuli were separated by either 150 or ...
  • Overvliet, Krista E.; Azañón Gracia, Elena; Soto-Faraco, Salvador, 1970- (Elsevier, 2011)
    Remapping tactile events from skin to external space is an essential process for human behaviour. It allows us to refer tactile sensations to their actual externally based location, by combining anatomically based somatosensory ...
  • Pérez-Bellido, Alexis; Soto-Faraco, Salvador, 1970-; López-Moliner, Joan (American Physical Society, 2012)
    Cross-modal enhancement can be mediated both by higher-order effects due to attention and decision making and by detection-level stimulus-driven interactions. However, the contribution of each of these sources to behavioral ...
  • Lee, Namyoon; Morales-Jiménez, David; Lozano Solsona, Angel; Heath, R. W., Jr. (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper characterizes the performance of coordinated beamforming with dynamic clustering. A downlink model based on stochastic geometry is put forth to analyze the performance of such base station (BS) coordination ...
  • Ventura Campos, Noelia; Sanjuán, Ana; González, Julio; Palomar García, María Ángeles; Rodríguez Pujadas, Aina; Sebastián Gallés, Núria; Deco, Gustavo; Ávila, César (Society for Neuroscience, 2013)
    Can learning capacity of the human brain be predicted from initial spontaneous functional connectivity (FC) between brain areas involved in a task? We combined task-related functional magnetic resonance imaging (fMRI) and ...
  • Maestre Gómez, Esteban; Blaauw, Merlijn; Bonada, Jordi, 1973-; Guaus, Enric; Pérez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Excitation-continuous music instrument control patterns are often not explicitly represented in current sound synthesis techniques when applied to automatic performance. Both physical model-based and sample-based synthesis ...
  • Cabral, Joana R. B.; Fernandes, Henrique M.; Van Hartevelt, Tim J.; James, Anthony C.; Kringelbach, Morten L.; Deco, Gustavo (American Institute of Physics (AIP), 2013)
    The neuropathology of schizophrenia remains unclear. Some insight has come from modern neuroimaging techniques, which offer an unparalleled opportunity to explore in vivo the structure and function of the brain. Using ...
  • Ton, Robert; Deco, Gustavo; Daffertshofer, Andreas (Public Library of Science (PLoS), 2014)
    The discrepancy between structural and functional connectivity in neural systems forms the challenge in understanding general brain functioning. To pinpoint a mapping between structure and function, we investigated the ...
  • Schoonenboom, Judith; Sligte, Henk; Moghnie, Ayman; Hernández Leo, Davinia; Stefanov, Krassen; Glahn, Christian; Specht, Marcus; Lemmers, Ruud (International Association of Online Engineering (IAOE), 2008)
    This paper describes an experiment to explore the effects of the TENCompetence infrastructure for supporting lifelong competence development which is now in development. This infrastructure provides structured, multi-leveled ...
  • Alvino, Serena; Asensio-Pérez, Juan I.; Dimitriadis, Yannis; Hernández Leo, Davinia (Taylor & Francis (Routledge), 2009)
    Distance and blended collaborative learning settings are usually characterized by different social structures defined in terms of groups' number, dimension, and composition; these structures are variable and can change ...
  • Benita, Jose María; Guillamon i Grabolosa, Antoni; Deco, Gustavo; Sanchez-Vives, Maria V (Frontiers Media, 2012)
    Short-term synaptic depression (STD) is a form of synaptic plasticity that has a large impact on network computations. Experimental results suggest that STD is modulated by cortical activity, decreasing with activity in ...
  • Biau, Emmanuel; Soto-Faraco, Salvador, 1970- (Frontiers, 2015)
    During social interactions, speakers often produce spontaneous gestures to accompany their speech. These coordinated body movements convey communicative intentions, and modulate how listeners perceive the message in a ...
  • Mungara, Ratheesh K.; Morales-Jiménez, David; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Capitalizing on the analytical potency of stochastic geometry and on some new ideas to model intercell interference, this paper presents analytical expressions that enable quantifying the spectral efficiency of IA ...
  • 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 ...
  • 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 ...
