Theta frequency (4–8 Hz) fluctuations of the local field potential have long been implicated
in learning and memory. Human studies of episodic memory, however, have provided mixed …

In the mammalian brain information processing and storage rely on the complex coding and
decoding events performed by neuronal networks. These actions are based on the …

Retaining information in working memory is a demanding process that relies on cognitive
control to protect memoranda-specific persistent activity from interference,. However, how …

During systems-level consolidation, mnemonic representations initially reliant on the
hippocampus are thought to migrate to neocortical sites for more permanent storage, with an …

Cross-frequency coupling (CFC) reflects (nonlinear) interactions between signals of different
frequencies. Evidence from both patient and healthy participant studies suggests that CFC …

Neural oscillations subserve a broad range of functions in speech processing and language
comprehension. On the one hand, speech contains—somewhat—repetitive trains of air …

Already in his first report on the discovery of the human EEG in 1929, Berger showed great
interest in further elucidating the functional roles of the alpha and beta waves for normal …

Theta and gamma frequency oscillations occur in the same brain regions and interact with
each other, a process called cross-frequency coupling. Here, we review evidence for the …

This review focuses on the neuronal and circuit mechanisms involved in the generation of
the theta (θ) rhythm and of its participation in behavior. Data have accumulated indicating …

Gamma rhythms are commonly observed in many brain regions during both waking and
sleep states, yet their functions and mechanisms remain a matter of debate. Here we review …
