  Gil Rodríguez, Raquel; Vazquez-Corral, Javier; Bertalmío, Marcelo (SIAM (Society for Industrial and Applied Mathematics), 2019)

  Multiple-exposure approaches for high dynamic range (HDR) image generation share a set of building assumptions: that color channels are independent and that the camera response function (CRF) remains constant while changing ...
• On the nature of the word-reduction phenomenon: the contribution of bilingualism

  Rodriguez-Cuadrado, Sara; Baus, Cristina; Costa, Albert, 1970- (MDPI, 2019)

  An instance of the constraint satisfaction problem (CSP) is given by a family of constraints on overlapping sets of variables, and the goal is to assign values from a fixed domain to the variables so that all constraints ...
• Primate amygdala neurons simulate decision drocesses of social partners

  Grabenhorst, Fabian; Báez-Mendoza, Raymundo; Genest, Wilfried; Deco, Gustavo; Schultz, Wolfram (Elsevier, 2019)

  By observing their social partners, primates learn about reward values of objects. Here, we show that monkeys’ amygdala neurons derive object values from observation and use these values to simulate a partner monkey’s ...
• Low entropy map of brain oscillatory activity identifies spatially localized events

  Vila-Vidal, Manel; Pérez-Enríquez, Carmen; Principe, Alessandro; Rocamora, Rodrigo; Deco, Gustavo; Tauste Campo, Adrià (Elsevier, 2020)

  The spatial mapping of localized events in brain activity critically depends on the correct identification of the pattern signatures associated with those events. For instance, in the context of epilepsy research, a number ...
• Human confidence judgments reflect reliability-based hierarchical integration of contextual information

  Schustek, Philipp; Hyafil, Alexandre; Moreno-Bote, Rubén (Nature Research, 2019)

  Our immediate observations must be supplemented with contextual information to resolve ambiguities. However, the context is often ambiguous too, and thus it should be inferred itself to guide behavior. Here, we introduce ...
• Disrupted brain structural connectivity in pediatric bipolar disorder with psychosis

  Fernandes, Henrique M.; Cabral, Joana; van Hartevelt, Tim J.; Lord, Louis-David; Gleesborg, Carsten; Møller, Arne; Deco, Gustavo; Whybro, Peter C.; Petrovic, Predrag; James, Anthony C.; Kringelbach, Morten L. (Nature Research, 2019)

  Bipolar disorder (BD) has been linked to disrupted structural and functional connectivity between prefrontal networks and limbic brain regions. Studies of patients with pediatric bipolar disorder (PBD) can help elucidate ...
• Discovery of key whole-brain transitions and dynamics during human wakefulness and non-REM sleep

  Stevner, Angus B.A.; Vidaurre, Diego; Cabral, Joana; Rapuano, Kristina M.; Nielsen, Søren Føns Vind; Tagliazucchi, Enzo; Laufs, Helmut; Vuust, Peter; Deco, Gustavo; Woolrich, Mark W.; van Someren, Eus; Kringelbach, Morten L. (Nature Research, 2019)

  The modern understanding of sleep is based on the classification of sleep into stages defined by their electroencephalography (EEG) signatures, but the underlying brain dynamics remain unclear. Here we aimed to move ...
• Characterizing the dynamical complexity underlying meditation

  Escrichs, Anira; Sanjuán, Ana; Atasoy, Selen; López-González, Ane; Garrido, César; Càmara, Estela; Deco, Gustavo (Frontiers, 2019)

  Over the past 2,500 years, contemplative traditions have explored the nature of the mind using meditation. More recently, neuroimaging research on meditation has revealed differences in brain function and structure in ...
• Detecting determinism with improved sensitivity in time series: rank-based nonlinear predictability score

  Naro, Daniel; Rummel, Christian; Schindler, Kaspar A.; Andrzejak, Ralph Gregor (American Physical Society, 2014)

  The rank-based nonlinear predictability score was recently introduced as a test for determinism in point processes. We here adapt this measure to time series sampled from time-continuous flows. We use noisy Lorenz signals ...
• Indications of nonlinear deterministic and finite-dimensional structures in time series of brain electrical activity: dependence on recording region and brain state

  Andrzejak, Ralph Gregor; Lehnertz, Klaus; Mormann, Florian; Rieke, Christoph; David, Peter; Elger, Christian E. (American Physical Society, 2001)

  We compare dynamical properties of brain electrical activity from different recording regions and from different physiological and pathological brain states. Using the nonlinear prediction error and an estimate of ...
• Measuring nonstationarity by analyzing the loss of recurrence in dynamical systems

  Rieke, Christoph; Sternickel, Karsten; Andrzejak, Ralph Gregor; Elger, Christian E.; David, Peter; Lehnertz, Klaus (American Physical Society, 2002)

  We propose a measure for nonstationarity which is based on the analysis of distributions of temporal distances of neighboring vectors in state space. As an extension of previous techniques our method does not require a ...

• Bivariate surrogate techniques: necessity, strengths, and caveats

  Andrzejak, Ralph Gregor; Kraskov, Alexander; Stögbauer, Harald; Mormann, Florian; Kreuz, Thomas (American Physical Society, 2003)
