Neuronal activity in the brain gives rise to transmembrane currents that can be measured in
the extracellular medium. Although the major contributor of the extracellular signal is the …

Clocks tick, bridges and skyscrapers vibrate, neuronal networks oscillate. Are neuronal
oscillations an inevitable by-product, similar to bridge vibrations, or an essential part of the …

In order to understand the working brain as a network, it is essential to identify the
mechanisms by which information is gated between regions. We here propose that …

We observed robust coupling between the high-and low-frequency bands of ongoing
electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to …

Neuroelectric and imaging studies of meditation are reviewed. Electroencephalographic
measures indicate an overall slowing subsequent to meditation, with theta and alpha …

To understand dynamic cognitive processes, the high time resolution of EEG/MEG is
invaluable. EEG/MEG signals can play an important role in providing measures of functional …

Despite the several-thousand-fold increase of brain volume during the course of mammalian
evolution, the hierarchy of brain oscillations remains remarkably preserved, allowing for …

Recent theoretical work has suggested that brain oscillations in the theta band are involved
in active maintenance and recall of working memory representations. To test this theoretical …

To study the role of brain oscillations in working memory, we recorded the scalp
electroencephalogram (EEG) during the retention interval of a modified Sternberg task. A …

The central problem for cognitive neuroscience is to describe how cognitive processes arise
from brain processes. This review summarizes the recent evidence that synchronous neural …
