    • Chronic fluoxetine treatment induces structural plasticity and selective changes in glutamate receptor ... 
      Ampuero, E.; Rubio, F. J.; Falcón, R.; Sandoval, M.; Díaz Véliz, Emma; González, R. E.; Earle, N.; Dagnino Subiabre, A.; Aboitiz Domínguez, Francisco Javier; Orrego, F.; Wyneken, U. (PERGAMON-ELSEVIER SCIENCE LTD, 2010-08-11)
      It has been postulated that chronic administration of antidepressant drugs induces delayed structural and molecular adaptations at glutamatergic forebrain synapses that might underlie mood improvement. To gain further ...
    • Chronic stress decreases the expression of sympathetic markers in the pineal gland and increases plasma ... 
      Dagnino Subiabre, Alexies; Orellana, Juan A.; Carmona Fontaine, Carlos; Montiel, Juan; Díaz Véliz, Emma; Serón Ferré, María; Wyneken, Ursula; Concha, Miguel L.; Aboitiz Domínguez, Francisco Javier (BLACKWELL PUBLISHING, 2006-06)
      Chronic stress affects brain areas involved in learning and emotional responses. Although most studies have concentrated on the effect of stress on limbic-related brain structures, in this study we investigated whether ...
    • Chronic stress impairs acoustic conditioning more than visual conditioning in rats: Morphological and ... 
      Dagnino Subiabre, Alexies; Terreros, G.; Carmona Fontaine, Carlos; Zepeda Iriarte, Ramiro; Orellana, J. A.; Mora Gutiérrez, Sergio; Díaz Véliz, Emma; Aboitiz Domínguez, Francisco Javier (PERGAMON-ELSEVIER SCIENCE LTD, 2005)
      Chronic stress affects brain areas involved in learning and emotional responses. These alterations have been related with the development of cognitive deficits in major depression. The aim of this study was to determine ...
    • Chronic stress induces upregulation of brain-derived neurotrophic factor (BDNF) rnRNA and integrin alpha 5 ... 
      Dagnino Subiabre, Alexies; Zepeda Carreño, Rodrigo; Díaz Véliz, Emma; Mora Gutiérrez, Sergio; Aboitiz Domínguez, Francisco Javier (ELSEVIER, 2006-05-01)
      Chronic stress affects brain areas involved in learning and emotional responses. These alterations have been related with the development of cognitive deficits in major depression. Moreover, stress induces deleterious ...
    • Combinación de genotipos DRD4 y DAT1 constituye importante factor de riesgo en miembros de familias de ... 
      Henríquez B., Hugo; Henríquez H., Marcela; Carrasco Chaparro, Ximena; Rothhammer Achondo, Paula; Llop Romero, Elena; Aboitiz Domínguez, Francisco Javier; Rothhammer Engel, Francisco (SOC MEDICA SANTIAGO, 2008-06)
      Background: Attention deficit/hyperactivity disorder (ADHD) is a common, highly heritable neurobiological disorder of childhood onset, characterized by hyperactivity, impulsiveness, and/or inattentiveness. Aim: To search ...
    • Distribution of alleles of DRD4 and DAT1 genes of the dopaminergic system in the mixed Chilean population ... 
      Vieyra S, Gonzalo; Moraga V, Mauricio; Henríquez B, Hugo; Aboitiz Domínguez, Francisco Javier; Rothhammer Engel, Francisco (2003)
      Background: Genes for dopamine receptor DRD4 and dopamine transporter DAT1 are highly polymorphic. Two alleles of these genes, namely the DRD4.7 and the DAT1*9 are frequently associated to the attention deficit disorder ...
    • 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 ...
    • Neural Mechanisms of Human Perceptual Learning: Electrophysiological Evidence for a Two-Stage Process 
      Hamamé, Carlos M.; Cosmelli, Diego; Henríquez, Rodrigo; Aboitiz Domínguez, Francisco Javier (PUBLIC LIBRARY SCIENCE, 2011-04-26)
      Background: Humans and other animals change the way they perceive the world due to experience. This process has been labeled as perceptual learning, and implies that adult nervous systems can adaptively modify the way in ...
    • P300 amplitude is insensitive to working memory load in schizophrenia 
      Gaspar Ramos, Pablo; Ruiz, Sergio; Zamorano, Francisco; Altayó, Marcela; Pérez, Carolina; Bosman, Conrado A.; Aboitiz Domínguez, Francisco Javier (BIOMED CENTRAL LTD, 2011-02-15)
