Reduced power in alpha and theta bands in ADHD children during a visuo-spatial working memory task
(2017)
Deficits in visuo-spatial working memory (VSWM) are one the most common impairments in subjects with ADHD.
VSWM is associated with amplitude modulations in theta, alpha, and gamma bands. Specifically, increases in the ...
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 ...
Increase in Hippocampal Theta Oscillations during Spatial Decision Making
(2014-02)
The processing of spatial and mnemonic information is
believed to depend on hippocampal theta oscillations (5–12 Hz).
However, in rats both the power and the frequency of the theta
rhythm are modulated by locomotor ...
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 ...
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 ...
Uma avaliação de métodos de previsão aplicados à grandes quantidades de séries temporais univariadas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2012-12-06)
Time series forecasting is probably one of the most primordial interests on economics and econometrics, and the literature on this subject is extremely vast. Due to technological growth in recent decades, large amounts of ...
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 ...
