Reducción de artefactos en señales electroencefalográficas mediante nuevas técnicas de filtrado automático basadas en separación ciega de fuentes.
(Universitat Politècnica de Catalunya, 2010-06-21)
Tesi
Accés obertEl análisis cuantitativo y la interpretación de las señales electroencefalográficas (EEG) permiten la comprensión de la función cerebral, ayudando al diagnóstico de estados disfuncionales. Sin embargo, es conocido que ... -
Reduction of metallic interference in MEG signals using AMUSE
(2013)
Comunicació de congrés
Accés restringit per política de l'editorialMagnetoencephalography is a technique that can noninvasively measure the brain signal. There are many advantages of using this technique rather than similar procedures such as the EEG for the evaluation of medical diseases. ... -
Serotonergic psychedelics temporarily modify information transfer in humans
(2015-06-01)
Article
Accés obertBackground: 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
(2020-04-22)
Article
Accés obertObjective. 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
(Institute of Physics (IOP), 2015-05-27)
Article
Accés obertThe 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
(Oxford University Press, 2022-01-12)
Article
Accés obertBackground: 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
(2018-02-02)
Article
Accés obertBackground 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 ...
