      Accés restringit per política de l'editorial
      The electrical activity generated in contracting muscles is measured using electromyographic (EMG) signals. By placing an array of electrodes on the surface of the skin, surface EMG (sEMG) signals are recorded non-invasively. ...
    • 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 ...
    • Spatial distribution of HD-EMG improves identification of task and force in patients with incomplete spinal cord injury 

      Jordanic, Mislav; Rojas Martínez, Mónica; Mañanas Villanueva, Miguel Ángel; Alonso López, Joan Francesc (2016-04-29)
      Article
      Accés obert
      Background: Recent studies show that spatial distribution of High Density surface EMG maps (HD-EMG) improves the identification of tasks and their corresponding contraction levels. However, in patients with incomplete ...
    • 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 ...
    • Successful object encoding induces increased directed connectivity in presymptomatic early-onset Alzheimer's disease 

      Ochoa Gómez, John Fredy; Alonso López, Joan Francesc; Duque, Jon; Tobón, Carlos; Mañanas Villanueva, Miguel Ángel; Lopera, Francisco; Hernández Valdivieso, Alher Mauricio (2017-01-01)
      Article
      Accés obert
      Background: Recent studies report increases in neural activity in brain regions critical to episodic memory at preclinical stages of Alzheimer’s disease (AD). Although electroencephalography (EEG) is widely used in AD ...
    • The WOMEN-UP solution, a patient-centered innovative e-health tool for pelvic floor muscle training: qualitative and usability study during early-stage development 

      Angles, Sonia S.; López Frías, Lorena; Soler, Vicenç; Alonso López, Joan Francesc; Kastelein, Arnoud W.; de Graaf, Boris C.; Vodegel, Eva; Tervo, Jaana; Baban, Adriana; Espuña Pons, Montserrat (2021-07-23)
      Article
      Accés obert
      e-Health may enhance self-management of pelvic floor muscle training (PFMT) to treat stress urinary incontinence (SUI). It is crucial to involve patients in planning, developing and monitoring the optimal e-Health solution. ...
    • 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 ...
    • Towards the application of HD-EMG decomposition in clinical practice 

      Mañanas Villanueva, Miguel Ángel; Rojas Martínez, Mónica; Alonso López, Joan Francesc (2016-06)
      Article
      Accés restringit per política de l'editorial
      The electromyography (EMG) signal is the summation of traveling motor unit (MU) action potentials that propagate along the fibers from the neuromuscular junction (Innervation Zone, IZ) to the tendons with a certain conduction ...
    • Use of frequency feature of HD-EMG in identification of upper-limb motor tasks 

      Jordanic, Mislav; Rojas Martínez, Mónica; Mañanas Villanueva, Miguel Ángel; Alonso López, Joan Francesc (Asociación Nicolo, 2017)
