  • Díaz, Begoña; Mitterer, Holger; Broersm, Mirjam; Escera, Carles; Sebastián Gallés, Núria (Cambridge University Press, 2015)
    People differ in their ability to perceive second language (L2) sounds. In early bilinguals the variability in learning L2 phonemes stems from speech-specific capabilities (Díaz, Baus, Escera, Costa & Sebastián-Gallés, ...
  • Nicolas Duchateau; Filip Loncaric; Maja Cikes; Adelina Doltra; Marta Sitges; Bijnens, Bart (Elsevier, 2020)
    Variability in global and regional peak strain has been thoroughly studied, but variability in spatiotemporal myocardial strain patterns has not been studied as well. This study reports on such variability and its implications ...
  • Mochol, Gabriela; Wójcik, Daniel K.; Wypych, Marek; Wróbel, Andrzej; Waleszczyk, Wioletta J. (Society for Neuroscience, 2010)
    Visually responding neurons in the superficial, retinorecipient layers of the cat superior colliculus receive input from two primarily parallel information processing channels, Y and W, which is reflected in their velocity ...
  • Bertalmío, Marcelo; Levine, Stacey (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    When taking pictures in a dark scene with artificial lighting, the ambient light is not sufficient for most cameras to obtain both accurate color and detail information. The exposure bracketing feature usually available ...
  • Cyriac, Praveen; Canham, Trevor; Kane, David; Bertalmío, Marcelo (Springer, 2020)
    Many challenges that deal with processing of HDR material remain very much open for the film industry, whose extremely demanding quality standards are not met by existing automatic methods. Therefore, when dealing with HDR ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Gamut mapping is the problem of transforming the colors of image or video content so as to fully exploit the color palette ofthe display device where the content will be shown, while preserving the artistic intent of the ...
  • Mathews, Zenon; Cetnarski, Ryszard; Verschure, Paul F. M. J. (Frontiers Media, 2015)
    Prediction plays a key role in control of attention but it is not clear which aspects of prediction are most prominent in conscious experience. An evolving view on the brain is that it can be seen as a prediction machine ...
  • Bertalmío, Marcelo; Calatroni, Luca; Franceschi, Valentina; Franceschiello, Benedetta; Gómez Villa, Alexander; Prandi, Dario (American Physiological Society, 2020)
    We reproduce suprathreshold perception phenomena, specifically visual illusions, by Wilson–Cowan (WC)-type models of neuronal dynamics. Our findings show that the ability to replicate the illusions considered is related ...
  • Brunellière, Angèle; Sánchez García, Carolina, 1984-; Ikumi Montserrat, Nara, 1986-; Soto-Faraco, Salvador, 1970- (Elsevier, 2013)
    Audiovisual speech perception has been frequently studied considering phoneme, syllable and word processing levels. Here, we examined the constraints that visual speech information might exert during the recognition of ...
  • Gómez Villa, Alexander; Bertalmío, Marcelo; Malo, Jesús (American Physiological Society, 2020)
    In this paper, we study the communication efficiency of a psychophysically tuned cascade of Wilson–Cowan and divisive normalization layers that simulate the retina-V1 pathway. This is the first analysis of Wilson–Cowan ...
  • Pérez-Bellido, Alexis; Ernst, Marc O.; Soto-Faraco, Salvador, 1970-; López-Moliner, Joan (Association for Research in Vision and Ophthalmology (ARVO), 2015)
    Recent studies have proposed that some cross-modal illusions might be expressed in what were previously thought of as sensory-specific brain areas. Therefore, one interesting question is whether auditory-driven visual ...
  • Deneux, Thomas; Masquelier, Timothée; Bermudez, Maria A.; Masson, Guillaume S.; Deco, Gustavo; Vanzetta, Ivo (Society of Photo Optical Instrumentation Engineers (SPIE), 2017)
    Increasing evidence suggests that sensory stimulation not only changes the level of cortical activity with respect to baseline but also its structure. Despite having been reported in a multitude of conditions and preparations ...
  • Farrús, Mireia (ACM Association for Computer Machinery, 2018)
    Humans are able to identify other people’s voices even in voice disguise conditions. However, we are not immune to all voice changes when trying to identify people from voice. Likewise, automatic speaker recognition systems ...
  • Oubel, E.; Cebral, J.R.; De Craene, Mathieu; Blanc, R.; Blasco, Jordi; Macho, Juan M.; Putman, C.M.; Frangi Caregnato, Alejandro (Institute of Physics (IOP), 2010)
    The quantification of wall motion in cerebral aneurysms is becoming important owing to its potential connection to rupture, and as a way to incorporate the effects of vascular compliance in computational fluid dynamics ...
  • Birulés-Muntané, Joan; Soto-Faraco, Salvador, 1970- (Public Library of Science (PLoS), 2016)
    Watching English-spoken films with subtitles is becoming increasingly popular throughout the world. One reason for this trend is the assumption that perceptual learning of the sounds of a foreign language, English, will ...
  • Purwins, Hendrik (Elsevier, 2010)
  • Deco, Gustavo; Scarano, Leandro; Soto-Faraco, Salvador, 1970- (Society for Neuroscience, 2007)
    Recent single-cell studies in monkeys (Romo et al., 2004) show that the activity of neurons in the ventral premotor cortex covaries with the animal's decisions in a perceptual comparison task regarding the frequency of ...
  • Arandía Romero, Iñigo; Nogueira Mañas, Ramon; Mochol, Gabriela; Moreno Bote, Rubén (Elsevier, 2017)
    Nowadays, it is possible to record the activity of hundreds of cells at the same time in behaving animals. However, these data are often treated and analyzed as if they consisted of many independently recorded neurons. How ...
  • Chicharro Raventós, Daniel; Kreuz, Thomas; Andrzejak, Ralph Gregor (Elsevier, 2011)
    Time scale parametric spike train distances like the Victor and the van Rossum distances/nare often applied to study the neural code based on neural stimuli discrimination./nDifferent neural coding hypotheses, such as rate ...
  • Iacozza, Sara; Costa, Albert, 1970-; Duñabeitia, Jon Andoni (Public Library of Science (PLoS), 2017)
    Foreign languages are often learned in emotionally neutral academic environments which differ greatly from the familiar context where native languages are acquired. This difference in learning contexts has been argued to ...
