Increased coherence among striatal regions in the theta range during attentive wakefulness
(Associação Brasileira de Divulgação Científica, 2012)
The striatum, the largest component of the basal ganglia, is usually subdivided into associative, motor and limbic components. However, the electrophysiological interactions between these three subsystems during behavior ...
Delta band activity contributes to the identification of command following in disorder of consciousness
(Nature, 2021)
The overt or covert ability to follow commands in patients with disorders of consciousness is considered a sign of awareness and has recently been defined as cortically mediated behaviour. Despite its clinical relevance, ...
Envelope analysis links oscillatory and arrhythmic EEG activities to two types of neuronal synchronization
(Academic Press INC Elsevier Science, 2018)
Traditionally, EEG is understood as originating from the synchronous activation of neuronal populations that generate rhythmic oscillations in specific frequency bands. Recently, new neuronal dynamics regimes have been ...
The effects of bromazepam over the temporo-parietal areas during the performance of a visuomotor task: A qEEG study
(ELSEVIER IRELAND LTD, 2011)
This study investigated the effects of bromazepam on qEEG when 14 healthy subjects were asked to perform a visuomotor task (i.e., motor vehicle driving task). The subjects were exposed to two experimental conditions: the ...
Premotor and occipital theta asymmetries as discriminators of memory- and stimulus-guided tasks
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The saccadic paradigm has been used to investigate specific cortical networks involving visuospatial attention. We examined whether asymmetry in theta and beta band differentiates the role of the hemispheres during the ...
Theta and alpha frequency modulation by lexical-syntactic information during a lexical decision taskModulación de las frecuencias theta y alfa por información léxico-sintáctica en una tarea de decisión léxicaModulação das freqüências teta e alfa por informação lexico-sintática em uma tarefa de decisão lexical
(Universidade Federal de Santa Catarina, 2014-12)
Estudiamos incrementos (ERS) y disminuciones (ERD) relacionadas con eventos en la potencia de las bandas alfa y theta asociadas con una divergencia a nivel léxico-sintáctico entre el prime y la meta durante una tarea de ...
Responsiveness of sensorimotor cortex during pharmacological intervention with bromazepam
(ELSEVIER IRELAND LTD, 2008)
The aim of this study was to investigate the influence of bromazepam on EEG and the motor learning process when healthy subjects were submitted to a typewriting task. We investigated bromazepam due to its abuse by various ...
Modelling the relationships between EEG signals, movement kinematics and outcome in soccer kicking
(2022-01-01)
The contribution of cortical activity (e.g. EEG recordings) in various brain regions to motor control during goal-directed manipulative tasks using lower limbs remains unexplored. Therefore, the aim of the current study ...
Complex, multifocal, individual-specific attention-related cortical functional circuits
(Sociedad de Biología de Chile, 2007)
Minor and Unsystematic Cortical Topographic Changes of Attention Correlates between Modalities
(PUBLIC LIBRARY SCIENCE, 2010)
In this study we analyzed the topography of induced cortical oscillations in 20 healthy individuals performing simple attention tasks. We were interested in qualitatively replicating our recent findings on the localization ...
