Doctoral thesis
Open AccessLa enfermedad pulmonar obstructiva crónica (EPOC) es la enfermedad crónica de los pulmones más común representando una causa importante de incapacidad y de muerte. La actividad respiratoria está definida en gran medida por ... -
An improved dynamic model for the respiratory response to exercise
(2018-02-07)
Article
Open AccessRespiratory system modeling has been extensively studied in steady-state conditions to simulate sleep disorders, to predict its behavior under ventilatory diseases or stimuli and to simulate its interaction with mechanical ... -
A novel spatial feature for the identification of motor tasks using high-density electromyography
(MDPI AG, 2017-07-08)
Article
Open AccessEstimation of neuromuscular intention using electromyography (EMG) and pattern recognition is still an open problem. One of the reasons is that the pattern-recognition approach is greatly influenced by temporal changes in ... -
Aplicación de la entropía condicional para el análisis del EEG bajo terapia farmacológica
(CEA, 2009)
Conference lecture
Restricted access - publisher's policyEl análisis del electroencefalograma humano constituye una herramienta muy útil para la evaluación de la biodisponibilidad de un fármaco en el cerebro. Se ha aplicado el calculo de entropía condicional a señales ... -
A real-time method for decoding the neural drive to muscles using single-channel intra-muscular EMG recordings
(2017-09-01)
Article
Open AccessThe neural command from motor neurons to muscles — sometimes referred to as the neural drive to muscle — can be identified by decomposition of electromyographic (EMG) signals. This approach can be used for inferring the ... -
Assessment of the pharmacological effects of alprazolam on electroencephalography using connectivity indexes not affected by volume conduction
(2015)
Conference lecture
Open AccessElectroencephalographic analysis techniques have become a very useful tool to assess brain activity and interactions between cerebral regions, that is, the so-called cerebral connectivity analysis. The effects of some drugs ... -
Assessment of weaning indexes based on diaphragm activity in mechanically ventilated subjects after cardiovascular surgery. A pilot study
(2017-06)
Article
Open AccessOBJECTIVE: The aim of this pilot study was to evaluate the feasibility of surface electromyographic signal derived indexes for the prediction of weaning outcomes among mechanically ventilated subjects after cardiac surgery. ... -
A synchronization system for the analysis of biomedical signals recorded with different devices from mechanically ventilated patients
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference lecture
Restricted access - publisher's policyConducting research associated with mechanically ventilated patients often requires the recording of several biomedical signals to dispose of multiple sources of information to perform a robust analysis. This is especially ... -
Auditory P3a and P3b neural generators in schizophrenia: An adaptive sLORETA P300 localization approach
(2015-12)
Article
Open AccessThe present study investigates the neural substrates underlying cognitive processing in schizophrenia (Sz) patients. To this end, an auditory 3-stimulus oddball paradigm was used to identify P3a and P3b components, elicited ... -
Automated detection of epileptic ripples in MEG using beamformer-based virtual sensors

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 ... -
