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 ...
Selective Coupling between Theta Phase and Neocortical Fast Gamma Oscillations during REM-Sleep in Mice
(2011)
Background: The mammalian brain expresses a wide range of state-dependent network oscillations which vary in frequency
and spatial extension. Such rhythms can entrain multiple neurons into coherent patterns of activity, ...
Brain to brain coupling in the gamma band as a marker of shared intentionality
(Frontiers Media, 2020)
Cooperation and competition are two ways of social interaction keys to life in society. Recent EEG-based hyperscanning studies reveal that cooperative and competitive interactions induce an increase in interbrain coupling. ...
Theta and Alpha Oscillation Impairments in Autistic Spectrum Disorder Reflect Working Memory Deficit
(2017)
A dysfunction in the excitatory–inhibitory (E/I) coordination in neuronal assembly has been proposed as a possible neurobiological mechanism of Autistic Spectrum Disorder (ASD). However, the potential impact of this mechanism ...
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 ...
Understanding dual task performance in humans : electrophysiological correlates of interferences and costs between motor and working memory tasks at different levels of workload
(2019)
The simultaneous execution of two different tasks is associated with interference
processes that produce a decrease in the performance of one or both duties, a
common phenomenon whose neural mechanisms are not yet ...
