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 brain's design? Mammalian cortical neurons form behavior-dependent oscillating networks of various sizes, which span five orders of magnitude in frequency. These oscillations are phylogenetically preserved, suggesting that they are functionally relevant. Recent findings indicate that network oscillations bias… 
Synaptic mechanisms of synchronized gamma oscillations in inhibitory interneuron networks
TLDR
Experimental analysis in the hippocampus and the neocortex and computational analysis suggests that synaptic specialization turns interneuron networks into robust gamma frequency oscillators.

TLDR
Evidence that synchronous neural oscillations in theta and gamma bands reveal much about the origin and nature of cognitive processes such as learning and memory is presented and the novel analyzing algorithms of neural oscillation are introduced, which is a directionality index of neural information flow (NIF) as a measure of synaptic plasticity.
Exploring the Function of Neural Oscillations in Early Sensory Systems
TLDR
This work will highlight recent work in the early visual pathway that shows how oscillations can multiplex different types of signals to increase the amount of information that spike trains encode and transmit.
Slow oscillations in neural networks with facilitating synapses
TLDR
It is shown by means of analytical solutions and simulations that facilitating excitatory (Ef) synapses onto interneurons in a neural network play a fundamental role, not only in shaping the frequency of slow oscillations, but also in determining the form of the up and down states observed in electrophysiological measurements.
Broadband macroscopic cortical oscillations emerge from intrinsic neuronal response failures
TLDR
It is shown how macroscopic oscillations emerge in solely excitatory random networks and without topological constraints and that these oscillations stem from the counterintuitive underlying mechanism—the intrinsic stochastic neuronal response failures (NRFs).
Motor cortical network oscillations driven by voltage‐ and ligand‐gated currents
TLDR
The role played by several glutamate receptors as well as voltage-gated ion channels and neurotransmitter receptors are revealed in the generation of neocortical ∼10 Hz oscillations in vitro, similar to those observed in humans and rats in vivo during myoclonus.
Neuronal Activity Patterns During Hippocampal Network Oscillations In Vitro
TLDR
This chapter is to summarize recent findings from different laboratories' works in in vitro preparations highlighting the importance of different neuronal activity patterns of hippocampal principal cells and different subtypes of interneurons during network oscillations.
Tick‐tock, spinal motor neurons go with the cortical clock in young infants
TLDR
A significant EEG–EMG coherence in the beta-band can be observed in infants aged 2–6 months for both leg and arm muscles, but not in younger (<2 months) or older (6–15 months) infants (see, however, Kanazawa et al. 2014).

Thalamocortical oscillations in the sleeping and aroused brain.
TLDR
Analysis of cortical and thalamic networks at many levels, from molecules to single neurons to large neuronal assemblies, with a variety of techniques, is beginning to yield insights into the mechanisms of the generation, modulation, and function of brain oscillations.
Communication between neocortex and hippocampus during sleep in rodents
TLDR
A robust correlation of neuronal discharges between the somatosensory cortex and hippocampus on both slow and fine time scales in the mouse and rat is shown, suggesting that oscillation-mediated temporal links coordinate specific information transfer between neocortical and hippocampal cell assemblies.
Interactions between membrane conductances underlying thalamocortical slow-wave oscillations.
TLDR
A coherent framework that accounts for a large body of experimental data at the ion-channel, single-cell, and network levels is suggested and physiological roles for the highly synchronized oscillations of slow-wave sleep are suggested.
Dynamic predictions: Oscillations and synchrony in top–down processing
TLDR
It is argued that coherence among subthreshold membrane potential fluctuations could be exploited to express selective functional relationships during states of expectancy or attention, and these dynamic patterns could allow the grouping and selection of distributed neuronal responses for further processing.
Fast Oscillations in Cortical Circuits
TLDR
Fast Oscillations in Cortical Circuits uses a combination of electrophysiological and computer modeling techniques to analyze how large networks of neurons can produce both epileptic seizures and functionally relevant synchronized oscillations.
Organization of cell assemblies in the hippocampus
TLDR
Here it is found that the spike times of hippocampal pyramidal cells can be predicted more accurately by using the Spike times of simultaneously recorded neurons in addition to the animals location in space, suggesting that cell assemblies are synchronized at this timescale.
