    • Phase-amplitude response functions for transient-state stimuli 

      Castejón i Company, Oriol; Guillamon Grabolosa, Antoni; Huguet Casades, Gemma (2013-08)
      Article
      Accés obert
      The phase response curve (PRC) is a powerful tool to study the effect of a perturbation on the phase of an oscillator, assuming that all the dynamics can be explained by the phase variable. However, factors like the rate ...

    • Phase-locked states in oscillating neural networks and their role in neural communication 

      Pérez Cervera, Alberto; Martínez-Seara Alonso, M. Teresa; Huguet Casades, Gemma (2020-01-01)
      Article
      Accés obert
      The theory of communication through coherence (CTC) proposes that brain oscillations reflect changes in the excitability of neurons, and therefore the successful communication between two oscillating neural populations ...

    • Phase-locking patterns underlying effective communication in exact firing rate models of neural networks 

      Huguet Casades, Gemma; Reyner Parra, David (Public Library of Science (PLOS), 2022-05-18)
      Article
      Accés obert
      Macroscopic oscillations in the brain have been observed to be involved in many cognitive tasks but their role is not completely understood. One of the suggested functions of the oscillations is to dynamically modulate ...

    • Phasic firing and coincidence detection by subthreshold negative feedback: divisive or subtractive or, better, both 

      Huguet Casades, Gemma; Meng, Xiangying; Rinzel, John (2017-02-02)
      Article
      Accés obert
      Phasic neurons typically fire only for a fast-rising input, say at the onset of a step current, but not for steady or slow inputs, a property associated with type III excitability. Phasic neurons can show extraordinary ...

    • Quasiperiodic perturbations of heteroclinic attractor networks 

      Delshams Valdés, Amadeu; Guillamon Grabolosa, Antoni; Huguet Casades, Gemma (Institute of Physics (IOP), 2018-10-01)
      Article
      Accés obert
      We consider heteroclinic attractor networks motivated by models of competition between neural populations during binocular rivalry. We show that gamma distributions of dominance times observed experimentally in binocular ...

      Accés restringit a la comunitat UPC

    • The role of hyperbolic invariant objects: From Arnold diffusion to biological clocks 

      Huguet Casades, Gemma (Universitat Politècnica de Catalunya, 2008-10-16)
      Tesi
      Accés obert
      El marc d'aquesta tesi són els objectes invariants hiperbòlics (tors amb bigotis, cicles límit, NHIM,. . .), que constitueixen, per aquesta tesi, els objectes essencials per a l'estudi de diversos problemes des de la difusió ...

    • The uncoupling limit of identical Hopf bifurcations with an application to perceptual bistability 

      Pérez Cervera, Alberto; Ashwin, Peter; Huguet Casades, Gemma; Rankin, James; Martínez-Seara Alonso, M. Teresa (2019-12-01)
      Article
      Accés obert
      We study the dynamics arising when two identical oscillators are coupled near a Hopfbifurcation where we assume a parameter uncouples the system at = 0. Using anormal form forN= 2 identical systems undergoing Hopf bifurcation, ...

    • Traveling waves in a model for cortical spreading depolarization with slow-fast dynamics 

      Reyner Parra, David; Bonet Revés, Carles; Martínez-Seara Alonso, M. Teresa; Huguet Casades, Gemma (American Institute of Physics (AIP), 2023-08-29)
      Article
      Accés obert
      Cortical spreading depression and spreading depolarization (CSD) are waves of neuronal depolarization that spread across the cortex, leading to a temporary saturation of brain activity. They are associated with various ...

    • Type III excitability, slope sensitivity and coincidence detection 

      Meng, Xiangying; Huguet Casades, Gemma; Rinzel, John (American Institute of Mathematical Sciences, 2012-08-01)
      Article
      Accés obert
      Some neurons in the nervous system do not show repetitive firing for steady currents. For time-varying inputs, they fire once if the input rise is fast enough. This property of phasic firing is known as Type III excitability. ...
