Intracranial high-frequency activity (HFA), which refers to fast fluctuations in
electrophysiological recordings, increases during memory processing. Two views have …

Despite advances in understanding the cellular and molecular processes underlying
memory and cognition, and recent successful modulation of cognitive performance in brain …

Both theoretical and experimental animal work supports the hypothesis that transient
oscillatory synchronization of neuronal assemblies at gamma frequencies (30–100Hz) is …

High frequency oscillations are associated with normal brain function, but also increasingly
recognized as potential biomarkers of the epileptogenic brain. Their role in human cognition …

This mini-symposium summarizes recent findings concerning the role of brain oscillations in
human cognition. Two rhythms that show particularly strong behavioral correlates are the 4 …

Gamma frequency activity (30–150 Hz) is induced in cognitive tasks and is thought to reflect
underlying neural processes. Gamma frequency activity can be recorded directly from the …

The synchronization between neural oscillations at different frequencies has been proposed
as a core mechanism for the coordination and integration of neural systems at different …

Oscillatory activity in the gamma-band range (> 30 Hz) has been proposed as a correlate of
cortical network synchronization. In human electroencephalogram (EEG), enhanced …

Although the hippocampus plays a crucial role in encoding and retrieval of contextually
mediated episodic memories, considerable controversy surrounds the role of the …

Coherent high-frequency neuronal activity has been proposed as a physiological indicator
of perceptual and higher cognitive processes. Some of these processes can only be …
