    • The Spatial and Temporal Construction of Confidence in the Visual Scene 

      Graziano, Martín; Sigman, Mariano (2009-03-17)
      Human subjects can report many items of a cluttered field a few hundred milliseconds after stimulus presentation. This memory decays rapidly and after a second only 3 or 4 items can be stored in working memory. Here we ...

    • The brain’s router : a cortical network model of serial processing in the primate brain 

      Zylberberg, Ariel (2010-04-29)
      The human brain efficiently solves certain operations such as object recognition and categorization through a massively parallel network of dedicated processors. However, human cognition also relies on the ability to perform ...

    • Collective behavior in the spatial spreading of obesity 

      Gallos, Lazaros K.; Barttfeld, Pablo; Havlin, Shlomo; Sigman, Mariano; Makse, Hernán A. (2012-06-12)
      Obesity prevalence is increasing in many countries at alarming levels. A difficulty in the conception of policies to reverse these trends is the identification of the drivers behind the obesity epidemics. Here, we implement ...

    • Neural processing of emotional facial and semantic xxpressions in euthymic bipolar disorder (BD) and its association with theory of mind (ToM) 

      Ibañez, Agustín; Urquina, Diego; Petroni, Agustín; Baez, Sandra; Lopez, Vladimir; Nascimento, Micaela do; Herrera, Eduar; Guex, Raphael; Hurtado, Esteban; Blenkmann, Esteban; Beltrachini, Leandro; Gelormini, Carlos; Sigman, Mariano; Lischinsky, Alicia; Torralva, Teresa; Torrente, Fernando; Cetkovich, Marcelo; Manes, Facundo (2012-10-08)
      Background: Adults with bipolar disorder (BD) have cognitive impairments that affect face processing and social cognition. However, it remains unknown whether these deficits in euthymic BD have impaired brain markers of ...

    • The neural basis of decision-making and reward processing in adults with euthymic bipolar disorder or attention-deficit/hyperactivity disorder (ADHD) 

      Ibañez, Agustín; Cetkovich, Marcelo; Petroni, Agustín; Urquina, Hugo; Baez, Sandra; Gonzalez-Gadea, María Luz; Kamienkowski, Juan Esteban; Torralva, Teresa; Torrente, Fernando; Strejilevich, Sergio; Teitelbaum, Julia; Hurtado, Esteban; Guex, Raphael; Melloni, Margherita; Lischinsky, Alicia; Sigman, Mariano; Manes, Facundo (2012-05-18)
      Background: Attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) share DSM-IV criteria in adults and cause problems in decision-making. Nevertheless, no previous report has assessed a decision-making ...

    • Organization of brain networks governed by long-range connections index autistic traits in the general population 

      Barttfeld, Pablo; Amoruso, Lucía; Ais, Joaquín; Cukier, Sebastián; Bavassi, Luz; Tomio, Ailin; Manes, Facundo; Ibañez, Agustín; Sigman, Mariano (2013-06-27)
      Background: The dimensional approach to autism spectrum disorder (ASD) considers ASD as the extreme of a dimension traversing through the entire population. We explored the potential utility of electroencephalography (EEG) ...

    • Attachment patterns trigger differential neural signature of emotional processing in adolescents 

      Escobar, María Josefina; Rivera-Rei, Álvaro; Decety, Jean; Huepe, David; Cardona, Juan Felipe; Canales-Johnson, Andrés; Sigman, Mariano; Helgiu, Elena; Mikulan, Ezequiel P.; Baez, Sandra; Manes, Facundo; Lopez, Vladimir; Ibañez, Agustín (2013-08-05)
      Background: Research suggests that individuals with different attachment patterns process social information differently, especially in terms of facial emotion recognition. However, few studies have explored social ...
