Predicción de crisis epilépticas utilizando el coeficiente de correlación producto-momento de Pearson a partir de un clasificador lineal de la distribución Gaussiana generalizadaEpileptic seizure prediction using Pearson's product-moment correlation coefficient of a linear classifier from generalized Gaussian modeling
(Ediciones Doyma S A, 2018-10)
Predecir una crisis epiléptica significa la capacidad de determinar de antemano el momento de una crisis con la mayor precisión posible. Un pronóstico correcto de un evento epiléptico en aplicaciones clínicas es un problema ...
Robust EEG-based cross-site and cross-protocol classification of states of consciousness
(Oxford University Press, 2018-11)
Determining the state of consciousness in patients with disorders of consciousness is a challenging practical and theoretical problem. Recent findings suggest that multiple markers of brain activity extracted from the EEG ...
At the heart of neurological dimensionality: Cross-nosological and multimodal cardiac interoceptive deficits
(Lippincott Williams, 2020-11)
Objective Neurological nosology, based on categorical systems, has largely ignored dimensional aspects of neurocognitive impairments. Transdiagnostic dimensional approaches of interoception (the sensing of visceral signals) ...
General bounds for electrode mislocation on the EEG inverse problem
(Elsevier Ireland, 2011-07)
We analyze the effect of electrode mislocation on the electroencephalography (EEG) inverse problem using the Cramér–Rao bound (CRB) for single dipolar source parameters. We adopt a realistic head shape model, and solve the ...
Two types of ictal phase-amplitude couplings in epilepsy patients revealed by spectral harmonicity of intracerebral EEG recordings
(Elsevier Ireland, 2020-08)
Objective: Spectral harmonicity of the ictal activity was analyzed regarding two clinically relevant aspects, (1) as a confounding factor producing ‘spurious’ phase-amplitude couplings (PAC) which may lead to wrong conclusions ...
Psychophysical and Electrophysiological Evidence for Enhanced Pain Facilitation and Unaltered Pain Inhibition in Acute Low Back Pain Patients
(Churchill Livingstone, 2017-05)
The aim of this case-control study was to examine differences in neural correlates of pain facilitatory and inhibitory mechanisms between acute low back pain (LBP) patients and healthy individuals. Pressure pain tolerance, ...
Differential neurophysiological correlates of retrieval of consolidated and reconsolidated memories in humans: An ERP and pupillometry study
(Academic Press Inc Elsevier Science, 2020-10)
Consolidated memories can return to a labile state if they are reactivated by unpredictable reminders. To persist, active memories must be re-stabilized through a process known as reconsolidation. Although there is consistent ...
Intracranial high-γ connectivity distinguishes wakefulness from sleep
(Academic Press Inc., 2018-04)
Neural synchrony in the γ-band is considered a fundamental process in cortical computation and communication and it has also been proposed as a crucial correlate of consciousness. However, the latter claim remains inconclusive, ...
Experimental studies on linguistic processing: a review of different experiences and their contributions
(Associação Brasileira de Linguística, 2020-07)
Esta mesa reúne tres presentaciones que tienen como eje común la realización de trabajos experimentales que aportan evidencia sustancial para comprender los procesos y las representaciones que subyacen a distintos dominios ...
Epileptic chorea: Another window into neural networks?
(Elsevier Science, 2018-11)
Paroxysmal abnormalities of motor or non-motor function are defined as epileptic when they co-occur with specific patterns of organized electrical activity as measured by scalp electroencephalography (EEG). Certain forms ...
