DOI: 10.1088/1741-2552/aa6e05
Abstract: OBJECTIVE The aim of this paper was to characterize brain non-stationarity during an auditory oddball task in schizophrenia (SCH). The level of non-stationarity was measured in the baseline and response windows of relevant tones in… read more here.

DOI: 10.1093/cercor/bhac080
Abstract: Successful sentence comprehension requires the binding, or composition, of multiple words into larger structures to establish meaning. Using magnetoencephalography, we investigated the neural mechanisms involved in binding at the syntax level, in a task where… read more here.

DOI: 10.1093/scan/nsac029
Abstract: Abstract Attention helps us to be aware of the external world, and this may be especially important when a threat stimulus predicts an aversive outcome. Electroencephalogram (EEG) alpha-band suppression has long been considered as a… read more here.

DOI: 10.1111/psyp.14051
Abstract: Alpha-band oscillations (8-14 Hz) are essential for attention and perception processes by facilitating the selection of relevant information. Directing visuospatial endogenous (voluntary) attention to a given location consistently results in a power suppression of alpha activity… read more here.

Evaluating the Evidence for the Functional Inhibition Account of Alpha-band Oscillations during Preparatory Attention.
Sign Up to like & getrecommendations! Published in 2023 at "Journal of cognitive neuroscience"
DOI: 10.1162/jocn_a_02009
Abstract: The functional inhibition account states that alpha-band (8-14 Hz) power implements attentional control by selectively inhibiting task-irrelevant neural representations. This account has been well supported by decades of correlational research showing attention-related changes in the… read more here.

DOI: 10.1371/journal.pcbi.1010012
Abstract: The dynamical and physiological basis of alpha band activity and 1/fβ noise in the EEG are the subject of continued speculation. Here we conjecture, on the basis of empirical data analysis, that both of these… read more here.

DOI: 10.1523/eneuro.0060-21.2022
Abstract: Abstract Variations in human behavior correspond to the adaptation of the nervous system to different internal and environmental demands. Attention, a cognitive process for weighing environmental demands, changes over time. Pupillary activity, which is affected… read more here.

DOI: 10.3389/fnhum.2022.965689
Abstract: Anticipatory attention is a neurocognitive state in which attention control regions bias neural activity in sensory cortical areas to facilitate the selective processing of incoming targets. Previous electroencephalographic (EEG) studies have identified event-related potential (ERP)… read more here.

Abstract: The results of quantitative electroencephalography (qEEG) studies on electroconvulsive therapy (ECT) have been inconsistent, and indicators of the efficacy of ECT have not been clearly identified. In this study, we examined whether qEEG could be… read more here.

Abstract: Previous research has associated alpha-band [8-12Hz] oscillations with inhibitory functions (Klimesch et al., 2007; Jensen and Mazaheri, 2010): for instance, several studies showed that visual attention increases alpha-band power in the hemisphere ipsilateral to the… read more here.
