    Treball Final de Grau
    Accés obert
    Realitzat a/amb:  New York University
    Experimental and theoretical study of membrane potentials of neurons in culture provide evidence of some of the mechanisms responsible for excitatory-inhibitory imbalance.
  • Coupled electromechanical model of the heart: Parallel finite element formulation 

    Lafortune, Pierre; Aris, Ruth; Vázquez, Mariano; Houzeaux, Guillaume (2012-01)
    Article
    Accés restringit per política de l'editorial
    In this paper, a highly parallel coupled electromechanical model of the heart is presented and assessed. The parallel-coupled model is thoroughly discussed, with scalability proven up to hundreds of cores. This work focuses ...
  • Generador de pulsos para la estimulación de cultivos de cardiomiocitos, con salida en corriente, bifásico y con eliminación activa de componente contínua 

    Araujo Sousa, David (Universitat Politècnica de Catalunya, 2015-10)
    Projecte Final de Màster Oficial
    Accés obert
    The reparation or recovering of damaged cardiac tissue caused by a heart attack or other disease that could damage the tissue, is one of the most attractive fields and possibly more important for tissue engineering research. ...
  • Initial analysis of SAR from a cell phone inside a vehicle by numerical computation. 

    Anzaldi, Gabriel; Silva Martínez, Fernando; Fernández Chimeno, Mireya; Quílez Figuerola, Marcos; Riu Costa, Pere Joan (Institution of Electrical and Electronics Engineers, 2007-05-31)
    Article
    Accés obert
    The purpose of this paper is to analyze the influence of the metallic structures of a realistic car body frame on the specific absorption rate (SAR) produced by a cell phone when a complete human body model is placed at ...
  • Integrating multi-unit electrophysiology and plastic culture dishes for network neuroscience 

    Morales Larramendi, Ricardo; Riss, M; Wang, Liang; Gavin, R; Del, Rio Ja; Alcubilla González, Ramón; Claverol Tinturé, Enrique (2008-11)
    Article
    Accés restringit per política de l'editorial
    The electrophysiological characterisation of cultured neurons is of paramount importance for drug discovery, safety pharmacology and basic research in the neurosciences. Technologies offering low cost, low technical ...
  • Numerical modelling of the electrophysiology of the neuron 

    Lang, Victoria Ashley (Universitat Politècnica de Catalunya, 2017-07)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    A majority of studies on the brain are focused at either the molecular level or organ level. Rarely do we see models that attempt to relate neuronal behaviors to symptoms of traumatic brain injury. Well-documented studies ...
