In this study, we introduced and applied a novel histogram transformation technique to enhance the interpretability and discriminative power of Cross-Frequency Coupling (CFC) maps derived from EEG signals for dyslexia ... -
Enhancing Neuronal Coupling Estimation by NIRS/EEG Integration.
Gallego-Molina, Nicolás J.; Ortiz-García, Andrés; Formoso, Marco A.; Martínez-Murcia, Francisco Jesús; Woo, Wai Lok (2024)
Neuroimaging techniques have had a major impact on medical science, allowing advances in the research of many neurological diseases and improving their diagnosis. In this context, multimodal neuroimaging approaches, based ... -
Explainable Exploration of the Interplay between HRV Features and EEG Local Connectivity Patterns in Dyslexia.
Formoso Trigo, Marco A.; Gallego-Molina, Nicolás J.; Ortiz-García, Andrés; Rodríguez-Rodríguez, Ignacio; Giménez-de-la-Peña, Almudena (2024-06-07)
Heart Rate Variability (HRV) is a measure of the variation in time between successive heartbeats, reflecting the influence of the au- tonomic nervous system on the heart. It can provide insights into the bal- ance between ... -
Generation of Virtual Children for testing a Recommendation System for Interventions with Children with Dyslexia.
Mateo-Trujillo, J. Ignacio; Rodríguez Rodríguez, Ignacio; Castillo-Barnes, Diego; Ortiz-García, Andrés; Luque-Vilaseca, Juan Luis (2024)
The LEEDUCA project has developed a recommendation system to generate intervention sessions tailored to children with dyslexia. Due to the limitations in obtaining real data for preliminary testing, the generation of in ... -
Inter-channel Granger Causality for Estimating EEG Phase Connectivity Patterns in Dyslexia
Rodríguez Rodríguez, Ignacio; Ortiz-García, Andrés; Formoso, Marco A.; Gallego-Molina, Nicolás J.; Luque-Vilaseca, Juan Luis (2022)
Methods like Electroencephalography (EEG) and magnetoencephalogram (MEG) record brain oscillations and provide an invaluable insight into healthy and pathological brain function. These signals are helpful to study and ... -
Multimodal image data fusion for Alzheimer’s Disease diagnosis by Sparse Representation
Ortiz-García, Andrés (KES, 2014-07-09)
Alzheimer's Diasese (AD) diagnosis can be carried out by analysing functional or structural changes in the brain. Functional changes associated to neurological disorders can be figured out by positron emission tomography ... -
Network Anomaly Classification by Support Vector Classifiers Ensemble and Non-linear Projection Techniques
De la Hoz Franco, Emiro; Ortiz-García, Andrés; Ortega, Julio; De la Hoz Correa, Eduardo (Springer, 2013-09)
Network anomaly detection is currently a challenge due to the number of different attacks and the number of potential attackers. Intrusion detection systems aim to detect misuses or network anomalies in order to block ports ... -
