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 …

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 the …

In gross anatomical terms, the hippocampal archicortex can be conceived as an “appendage”
of the large neocortex. In contrast to neocortical areas, the main output targets of the …

Pyramidal cells in the CA1 hippocampal region displayed transient network oscillations (200
hertz) during behavioral immobility, consummatory behaviors, and slow-wave sleep. …

Sharp wave ripples (SPW‐Rs) represent the most synchronous population pattern in the
mammalian brain. Their excitatory output affects a wide area of the cortex and several …

Theories on the functions of the hippocampal system are based largely on two fundamental
discoveries: the amnestic consequences of removing the hippocampus and associated …

A widely discussed hypothesis in neuroscience is that transiently active ensembles of neurons,
known as "cell assemblies," underlie numerous operations of the brain, from encoding …

How does the brain orchestrate perceptions, thoughts and actions from the spiking activity
of its neurons? Early single-neuron recording research treated spike pattern variability as …

… In a sequence of" cycles," György Buzsáki guides the reader from the physics of oscillations
through neuronal assembly organization to complex cognitive processing and memory …

A long-standing conjecture in neuroscience is that aspects of cognition depend on the brain's
ability to self-generate sequential neuronal activity. We found that reliably and continually …
