Functional differences of low- and high-frequency oscillatory dynamics during illusory border perception
(ELSEVIER, 2010)
Neuronal oscillations are an essential part of several brain processes like perception, memory and attention, but little is known about the simultaneous dynamics of different frequency bands in such processes. Here, we ...
Cortical Oscillatory Activity Is Critical for Working Memory as Revealed by Deficits in Early-Onset Schizophrenia
(SOC NEUROSCIENCE, 2009)
Impairments in working memory (WM) are a core cognitive deficit in schizophrenia. Neurophysiological models suggest that deficits during WM maintenance in schizophrenia may be explained by abnormalities in the GABAergic ...
Brain Mechanisms underlying prediction during conflict and value-based decision making
(Universidad del Desarrollo. Facultad de Gobierno, 2023)
People are able to solve conflictive situations and even anticipate them thanks to adaptive behavior derived from their experience and learning of contextual changes, that allows them to predict what might happen. This ...
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 ...
Efecto de la reducción de serotonina septal sobre la actividad theta hipocampal asociada a la memoria de trabajo espacial, en la rata
(Universidad Michoacana de San Nicolás de Hidalgo, 2016-12)
Hippocampal theta activity, which is strongly modulated by the septal medial/Broca's diagonal band neurons, has been linked to information processing of the hippocampus. Serotonin from the medial raphe nuclei desynchronizes ...
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, ...
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 understood. ...
Caracterização eletrofisiológica das oscilações delta e teta do hipocampo dorsal de ratos durante locomoção em esteira
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM PSICOBIOLOGIA, 2020-06-09)
The hippocampal theta rhythm (6-10 Hz) has been extensively studied since the 1950’s. These
researches have shown that the theta rhythm is involved with cognitive functions, sensorymotor integration, paradoxical sleep and ...
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 ...
