    • Alterations in EEG connectivity in healthy young adults provide an indicator of sleep depth 

      Migliorelli Falcone, Carolina Mercedes; Bachiller Matarranz, Alejandro; Andrade, Andreia G.; Alonso López, Joan Francesc; Mañanas Villanueva, Miguel Ángel; Borja Mallach, Cristina; Romero Lafuente, Sergio (2019-06-11)
      Article
      Open Access
      Current sleep analyses have used electroencephalography (EEG) to establish sleep intensity through linear and nonlinear measures. Slow wave activity (SWA) and entropy are the most commonly used markers of sleep depth. The ...
    • Auditory P3a and P3b neural generators in schizophrenia: An adaptive sLORETA P300 localization approach 

      Bachiller Matarranz, Alejandro; Romero Lafuente, Sergio; Molina, Vicente; Alonso López, Joan Francesc; Mañanas Villanueva, Miguel Ángel; Poza Crespo, Jesús; Hornero Sánchez, Roberto (2015-12)
      Article
      Open Access
      The present study investigates the neural substrates underlying cognitive processing in schizophrenia (Sz) patients. To this end, an auditory 3-stimulus oddball paradigm was used to identify P3a and P3b components, elicited ...
    • Choosing strategies to deal with artifactual EEG data in children with cognitive impairment 

      Tost Abadías, Ana; Migliorelli Falcone, Carolina Mercedes; Bachiller Matarranz, Alejandro; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel; García Cazorla, Àngels (2020)
      Conference lecture
      Open Access
      Rett syndrome is a disease that involves acute cognitive impairment and, consequently, a complex and varied symptomatology. This study evaluates the EEG signals of twenty-nine patients in order to implement an effective ...
    • Epileptic seizure prediction and onset zone localization using intracranial and scalp electroencephalographic and magnetoencephalographic signals 

      Marateb, Hamid Reza; Migliorelli Falcone, Carolina Mercedes; Bachiller Matarranz, Alejandro; Azimi, Tayebe; Nezhad, Farzad Ziaie; Mansourian, Marjan; Alonso López, Joan Francesc; Aparicio, Javier; San Antonio Arce, María Victoria; Romero Lafuente, Sergio; Mañanas Villanueva, Miguel Ángel (Institute of Physics (IOP), 2020-09)
      Part of book or chapter of book
      Restricted access - publisher's policy
      In this chapter, we discuss how intracranial or scalp electroencephalographic and magnetoencephalographic recordings could be used for epileptic seizure prediction and onset zone localization. The signal processing methods ...
    • 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
      Open Access
      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 ...
    • 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
      Open Access
      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 ...
