    • Attending to the heart is associated with posterior alpha band increase and a reduction in sensitivity to concurrent visual stimuli 

      Villena González, Mario; Moenne Loccoz, Cristóbal; Lagos, Rodrigo A.; Alliende, Luz M.; Billeke, Pablo; Aboitiz, Francisco; López, Vladimir; Cosmelli, Diego (Wiley, 2017)
      Attentional mechanisms have been studied mostly in specific sensory domains, such as auditory, visuospatial, or tactile modalities. In contrast, attention to internal interoceptive visceral targets has only recently begun ...
    • Brain signatures of moral sensitivity in adolescents with early social deprivation 

      Gómez, David Maximiliano; Escobar, María Josefina; Huepe, David; Decety, Jean; Sedeño, Lucas; Messow, Marie Kristin; Baez, Sandra; Rivera Rei, Álvaro; Canales Johnson, Andrés; Morales, Juan Pablo; Schröeder, Johannes; Manes, Facundo; López, Vladimir; Ibáñez, Agustín (Scientic Reports, 2014)
      The present study examined neural responses associated with moral sensitivity in adolescents with a background of early social deprivation. Using high-density electroencephalography (hdEEG), brain activity was measured ...
    • Compared to self immersion, mindful attention reduces salivation and automatic food bias 

      Baquedano, Constanza; Vergara, Rodrigo C.; López, Vladimir; Fabar, Catalina; Cosmelli, Diego; Lutz, Antoine (Nature Publishing Group, 2017)
      Immersing ourselves in food images can sometimes make it feel subjectively real, as if the actual food were right in front of us. Excessive self-immersion into mental content, however, is a hallmark of psychological distress, ...
    • Effect of phychostimulants on distinct attentional parameters in attentional deficit/hyperactivity disorder 

      Jaque López, Javier; López, Vladimir; Rojas, Daniel; Carrasco, Ximena; Rothhammer Achondo, Paula; García, Ricardo; Rothhammer Engel, Francisco; Aboitiz, Francisco (2004)
      Although there is extensive literature about the effects of stimulants on sustained attention tasks in attentional deficit/hyperactivity disorder (ADHD), little is known about the effect of these drugs on other attentional ...
    • Exogenous orienting of visual-spatial attention in ADHD children 

      Ortega, Rodrigo; López, Vladimir; Carrasco, Ximena; Anllo-Vento, Lourdes; Aboitiz, Francisco (2013)
      Visual spatial orienting of attention towards exogenous cues has been one of the attentional functions considered to be spared in ADHD. Here we present a design in which 60 (30 ADHD) children, age: 10.9±1.4, were asked to ...
    • Exogenous orientingofvisual-spatialattention in ADHDchildren 

      Ortega, Rodrigo; López, Vladimir; Carrasco Álvarez, Ximena; Anllo Vento, Lourdes; Aboitiz Domínguez, Francisco Javier (ElsevierB.V., 2013)
      Visual spatial orienting of attention towards exogenous cues has been one of the attentional functions considered to be spared in ADHD. Here we present a design in which 60 (30 ADHD) children, age: 10.9±1.4, were asked to ...
    • Frontal and executive dysfunction is a central aspect of ADHD 

      Carrasco, Ximena; López, Vladimir; Aboitiz, Francisco (2005)
      In the target article, Sagvolden and collaborators propose that attentional-deficit/hyperactivity disorder (ADHD) is the result of a general behavioral deficit which is mainly caused by a hypofunctioning mesolimbic ...
    • Lateral prefrontal activity as a compensatory strategy for deficits of cortical processing in Attention Deficit Hyperactivity Disorder 

      Zamorano, Francisco; Billeke, Pablo; Kausel, Leonie; Larrain, Josefina; Stecher, Ximena; Hurtado, José M.; López, Vladimir; Carrasco Chaparro, Ximena; Aboitiz, Francisco (Nature Publishing Group, 2017)
      Attention Deficit Hyperactivity Disorder (ADHD) is the most common neuropsychiatric disorder in childhood and is characterized by a delay of cortical maturation in frontal regions. In order to investigate interference ...
    • Methodological considerations related to sleep paradigm using event related potentials 

      Ibáñez, Agustín; San Martín, René; Hurtado, Esteban; López, Vladimir (SOC BIOLGIA CHILE, 2008)
      In the last few decades, several works on event related potentials (ERPs hereafter) during sleep have been reported. In Spite of numerous Studies, clear methodological rules for this kind Of Study are often missing, making ...
    • Mirror system deficit in ADHD? Study of Mu rhythm suppression during observation and imitation of emotion-related facial movements 

      López, Vladimir; Ortega, Rodrigo; Moenne, Cristóbal; Carrasco Chaparro, Ximena (Elsevier Science BV., 2016)
      Mu rhythm is an EEG oscillatory measure (9 -13 Hz), whose suppression during movement execution or action observation is considered an indicator of the activity of the human analog of the mirror neuron system. Detection ...
