TLDR
This work examines the generation of gamma oscillation currents in the hippocampus, using two-dimensional, 96-site silicon probes and identifies two gamma generators, one in the dentate gyrus and another in the CA3-CA1 regions.About:

Neuronal Oscillations in Cortical Networks
György Buzsáki,Andreas Draguhn +1 more
TL;DR: Recent findings indicate that network oscillations bias input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information.

Mechanisms of Gamma Oscillations
György Buzsáki,Xiao Jing Wang +1 more
TL;DR: The cellular and synaptic mechanisms underlying gamma oscillations are reviewed and empirical questions and controversial conceptual issues are outlined, finding that gamma-band rhythmogenesis is inextricably tied to perisomatic inhibition.

Synaptic mechanisms of synchronized gamma oscillations in inhibitory interneuron networks
TL;DR: Experimental analysis in the hippocampus and the neocortex and computational analysis suggests that synaptic specialization turns interneuron networks into robust gamma frequency oscillators.

TL;DR: Several rhythms and their interplay render neuronal communication effective, precise, and selective in neuronal groups.

TL;DR: The amnesic syndrome is presented as an extension of the theory to humans and the role of operators in the locale system is examined.

The brainweb: phase synchronization and large-scale integration.
TL;DR: It is argued that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.

Oscillatory responses in cat visual cortex exhibit inter-columnar synchronization which reflects global stimulus properties.
TL;DR: It is demonstrated here that neurons in spatially separate columns can synchronize their oscillatory responses, which has, on average, no phase difference, depends on the spatial separation and the orientation preference of the cells and is influenced by global stimulus properties.

Spectrum estimation and harmonic analysis
TL;DR: In this article, a local eigenexpansion is proposed to estimate the spectrum of a stationary time series from a finite sample of the process, which is equivalent to using the weishted average of a series of direct-spectrum estimates based on orthogonal data windows to treat both bias and smoothing problems.
