Alterations in EEG connectivity in healthy young adults provide an indicator of sleep depth
(2019-06-11)
Article
Open AccessCurrent 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 ... -
Automated detection of epileptic ripples in MEG using beamformer-based virtual sensors
(2017-08-01)
Article
Open AccessObjective. In epilepsy, high-frequency oscillations (HFOs) are expressively linked to the seizure onset zone (SOZ). The detection of HFOs in the noninvasive signals from scalp electroencephalography (EEG) and magnetoence ... -
Automatic BSS-based filtering of metallic interference in MEG recordings: definition and validation using simulated signals
(2015-05-27)
Article
Open AccessObjective. One of the principal drawbacks of magnetoencephalography (MEG) is its high sensitivity to metallic artifacts, which come from implanted intracranial electrodes and dental ferromagnetic prosthesis and produce a ... -
Choosing strategies to deal with artifactual EEG data in children with cognitive impairment
(2020)
Conference lecture
Open AccessRett 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 ... -
Choosing strategies to deal with artifactual eeg data in children with cognitive impairment
(2021-08-11)
Article
Open AccessRett 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 and classify them according to the ... -
Cognitive stimulation has potential for brain activation in individuals with Rett syndrome
(John Wiley & sons, 2021-11-18)
Article
Open AccessBackground: Knowledge regarding neuropsychological training in Rett syndrome (RS) is scarce. The aim of this study was to assess the outcome and the duration of the effect of cognitive stimulation on topographic EEG data ... -
Epileptic seizure prediction and onset zone localization using intracranial and scalp electroencephalographic and magnetoencephalographic signals
(Institute of Physics (IOP), 2020-09)
Part of book or chapter of book
Restricted access - publisher's policyIn 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 ... -
Evaluation of connectivity measures to identify seizure onset and propagation zones in refractory epilepsy: a case study with two different post- surgical outcomes
(2023)
Conference lecture
Restricted access - publisher's policyHigh Frequency Oscillations (HFO) have been found very useful in refractory epilepsy. They have been used to identify the epileptogenic zone and as a promising clinical biomarker for presurgical evaluation in childhood ... -
Identificación de contracciones isométricas de la extremidad superior en pacientes con lesión medular incompleta mediante características espectrales de la electromiografía de alta densidad (HD-EMG)
(Universidad de Oviedo, 2017)

Improving the ripple classification in focal pediatric epilepsy: identifying pathological high-frequency oscillations by Gaussian mixture model clustering
(2021-08-01)
Article
Open AccessObjective: High-frequency oscillations (HFOs) have emerged as a promising clinical biomarker for presurgical evaluation in childhood epilepsy. HFOs are commonly classified in stereo-encephalography as ripples (80–200 Hz) ... -
Influence of metallic artifact filtering on MEG signals for source localization during interictal epileptiform activity
(2016-03-02)
Article
Open AccessObjective. Medical intractable epilepsy is a common condition that affects 40% of epileptic patients that generally have to undergo resective surgery. Magnetoencephalography (MEG) has been increasingly used to identify the ... -
Influence of the number of trials on evoked motor cortical activity in EEG recordings
(2022-08-26)
Article
Open AccessObjective. Improvements in electroencephalography enable the study of the localization of active brain regions during motor tasks. Movement-related cortical potentials (MRCPs), and event-related desynchronization (ERD) and ... -
Methods for noninvasive localization of focal epileptic activity with magnetoencephalography
(Universitat Politècnica de Catalunya, 2017-06-28)
Doctoral thesis
Open AccessMagnetoencephalography (MEG) is a noninvasive brain signal acquisition technique that provides excellent temporal resolution and a whole-head coverage allowing the spatial mapping of sources. These characteristics make MEG ... -
Reduction of metallic interference in MEG signals using AMUSE
(2013)
Conference lecture
Restricted access - publisher's policyMagnetoencephalography 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. ... -
SGM: a novel time-frequency algorithm based on unsupervised learning improves high-frequency oscillation detection in epilepsy
(2020-04-22)
Article
Open AccessObjective. 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 ... -

Master thesis (pre-Bologna period)
Restricted access - author's decision
Covenantee: Laboratori d'Aplicacions BioacústiquesEste proyecto tiene como objetivo llevar a cabo la industrialización del bloque emisor de un sistema de medida de potenciales evocados. Partiendo de un prototipo anterior, se procederá a rediseñar y simular los circuitos ... -
The kappa opioid receptor and the sleep of reason: cortico-subcortical Imbalance following Salvinorin-A
(Oxford University Press, 2022-01-12)
Article
Open AccessBackground: 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 ...
