    • Serotonergic psychedelics temporarily modify information transfer in humans 

      Alonso López, Joan Francesc; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; Riba Serrano, Jordi (2015-06-01)
      Article
      Accés obert
      Background: Psychedelics induce intense modifications in the sensorium, the sense of "self," and the experience of reality. Despite advances in our understanding of the molecular and cellular level mechanisms of these ...
    • SGM: a novel time-frequency algorithm based on unsupervised learning improves high-frequency oscillation detection in epilepsy 

      Migliorelli Falcone, Carolina Mercedes; Bachiller Matarranz, Alejandro; Alonso López, Joan Francesc; Romero Lafuente, Sergio; Aparicio, Javier; Jacobs-Le Van, Julia; Mañanas Villanueva, Miguel Ángel; San Antonio-Arce, Victoria (2020-04-22)
      Article
      Accés obert
      Objective. We propose a novel automated method called the S-Transform Gaussian Mixture detection algorithm (SGM) to detect high-frequency oscillations (HFO) combining the strengths of different families of previously ...
    • Stress assessment based on EEG univariate features and functional connectivity measures 

      Alonso López, Joan Francesc; Romero Lafuente, Sergio; Ballester Verneda, Maria Rosa; Antonijoan Arbós, Rosa Maria; Mañanas Villanueva, Miguel Ángel (Institute of Physics (IOP), 2015-05-27)
      Article
      Accés obert
      The biological response to stress originates in the brain but involves different biochemical and physiological effects. Many common clinical methods to assess stress are based on the presence of specific hormones and on ...
    • The kappa opioid receptor and the sleep of reason: cortico-subcortical Imbalance following Salvinorin-A 

      Ona, Genis; Sampedro, Frederic; Romero Lafuente, Sergio; Valle, Marta; Camacho, Valle; Migliorelli Falcone, Carolina Mercedes; Mañanas Villanueva, Miguel Ángel; Antonijoan Arbós, Rosa Maria; Puntes, Montserrat; Coimbra, Jimena; Ballester Verneda, Maria Rosa; Garrido, Maite; Riba Serrano, Jordi (Oxford University Press, 2022-01-12)
      Article
      Accés obert
      Background: The mechanisms through which kappa opioid receptor (KOR) agonists induce psychotomimetic effects are largely unknown, although the modulation of this receptor has attracted attention for its clinical use. In ...
    • Topography of activation deficits in schizophrenia during P300 task related to cognition and structural connectivity 

      Molina Rodriguez, Vicente; Bachiller Matarranz, Alejandro; Luis García, Rodrigo de; Lubeiro Juárez, Alba; Poza Crespo, Jesús; Hornero Sánchez, Roberto; Alonso López, Joan Francesc; Mañanas Villanueva, Miguel Ángel; Marques, Patricia; Romero Lafuente, Sergio (2018-02-02)
      Article
      Accés obert
      Background The study of cerebral underpinnings of schizophrenia may benefit from the high temporal resolution of electromagnetic techniques, but its spatial resolution is low. However, source imaging approaches such as ...
