Brain oscillations in perception and memory
International Journal of Psychophysiology, 2000 Gamma oscillations, now widely regarded as functionally relevant signals of the brain, illustrate that the concept of event-related oscillations bridges the gap between single neurons and neural assemblies. Taking this concept further, we review experiments showing that oscillatory phenomena such as alpha, theta, or delta responses to events are ...

The frequency architecture of brain and brain body oscillations: an analysis [PDF]
European Journal of Neuroscience, 2018 AbstractResearch on brain oscillations has brought up a picture of coupled oscillators. Some of the most important questions that will be analyzed are, how many frequencies are there, what are the coupling principles, what their functional meaning is, and whether body oscillations follow similar coupling principles.

Genetics of human brain oscillations
International Journal of Psychophysiology, 2006In the last three decades, much emphasis has been placed on neural oscillations in vitro, in vivo, as well as in the human brain. These brain oscillations have been studied extensively in the resting electroencephalogram (EEG), as well as in the underlying evoked oscillations that make up the event-related potentials (ERPs).

Brain Oscillations and the Importance of Waveform Shape.
Trends in Cognitive Sciences, 2017Oscillations are a prevalent feature of brain recordings. They are believed to play key roles in neural communication and computation. Current analysis methods for studying neural oscillations often implicitly assume that the oscillations are sinusoidal.

Oscillatory fluctuations of local field potentials (LFPs) in the theta (4-8 Hz) and gamma (25-140 Hz) band are held to play a mechanistic role in various aspects of memory including the representation and off-line maintenance of events and sequences of events, the assessment of novelty, the induction of plasticity during encoding, as well as the ...

The study of brain oscillations associated with emotional picture processing has revealed conflicting findings. Although many studies observed a decrease in power in the alpha- and lower beta band, some studies observed an increase. Accordingly, the main

Brain Oscillations and Migraine
2020The rhythmic oscillations embedded in the spontaneous or evoked electroencephalographic (EEG) activity are closely related to the subtle cognitive processes of the brain. This review is aimed to provide a comprehensive overview of the studies investigating brain oscillations across various frequency ranges in migraine, using EEG and evoked potentials.

Spontaneous Brain Oscillations and Perceptual Decision-Making.
Trends in Cognitive Sciences, 2020Making rapid decisions on the basis of sensory information is essential to everyday behaviors. Why, then, are perceptual decisions so variable despite unchanging inputs?

Thalamocortical oscillations in the sleeping and aroused brain.
Science, 1993Sleep is characterized by synchronized events in billions of synaptically coupled neurons in thalamocortical systems. The activation of a series of neuromodulatory transmitter systems during awakening blocks low-frequency oscillations, induces fast rhythms, and allows the brain to recover full responsiveness.
