Cross-frequency interaction of the eye-movement related LFP signals in V1 of freely viewing monkeys
(2013)
Recent studies have emphasized the functional role of neuronal activity underlying oscillatory local field potential (LFP) signals during visual processing in natural conditions. While functionally relevant components in ...
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 ...
Long-range neural synchronization supports fast and efficient reading: EEG correlates of processing expected words in sentences
(Elsevier, 2013)
Word reading is heavily influenced by the information provided by previous context. In this study, we analyzed
the neurophysiological bases of sentence reading through the EEG activity elicited during reading the same ...
Neural oscillatory deficits in schizophrenia predict behavioral and neurocognitive impairments
(Frontiers Media, 2015)
Paying attention to visual stimuli is typically accompanied by event-related desynchronizations (ERD) of ongoing alpha (7-14 Hz) activity in visual cortex. The present study used time-frequency based analyses to investigate ...
Ways of making-sense: Local gamma synchronization reveals differences between semantic processing induced by music and language
(Elsevier, 2016)
Similar to linguistic stimuli, music can also prime the meaning of a subsequent word. However, it is so far unknown what is the brain dynamics underlying the semantic priming effect induced by music, and its relation to ...
Desvendando oscilações hipocampais através de comodulações
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2016-04-07)
Spectral analysis of extracellular electrophysiological recordings revealed that the
brain electrical activity is often organized in rhythmic patterns, known as neuronal
oscillations. Recently, it was discovered that ...
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 ...
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 ...
A graph-theoretical approach in brain functional networks. Possible implications in EEG studies
(2010)
Abstract
Background
Recently, it was realized that the functional connectivity networks estimated from actual brain-imaging ...
