TLDR
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.Abstract:
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 input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information.read more

Changes in parvalbumin immunoreactivity with aging in the central auditory system of the rat
TL;DR: Age-related changes in parvalbumin immunoreactivity were investigated in the inferior colliculus, medial geniculate body (MGB) and auditory cortex of two rat strains, normally aging Long-Evans (LE) and fast aging Fischer 344 (F344).

Gender differences in implicit and explicit processing of emotional facial expressions as revealed by event-related theta synchronization.
TL;DR: Gender differences in emotion processing for well-documented differences in social behavior are discussed and theta synchronization was more pronounced in the early processing stage than in the explicit mode.

Cortical functional network organization from autoregressive modeling of local field potential oscillations
TL;DR: A framework is presented for quantifying functional network organization in the brain by spectral analysis based on autoregressive modeling and Granger causality analysis has revealed information flow in the sensorimotor network that is consistent with a peripheral sensorsimotor feedback loop, and in the visual network that was consistent with top‐down anticipatory modulation of assemblies in the primary visual cortex.

TL;DR: The results support the hypothesis that self‐related information is temporally contained in the brain's resting state and can thus be featured by a temporal signature.

Toward More Versatile and Intuitive Cortical Brain–Machine Interfaces
TL;DR: This review will focus on several new topics in the arena of cortical prosthetics using: recordings from cortical areas outside motor cortex; local field potentials as a source of recorded signals; somatosensory feedback for more dexterous control of robotics; and new decoding methods that work in concert to form an ecology of decode algorithms.

Exploring complex networks
TL;DR: This work aims to understand how an enormous network of interacting dynamical systems — be they neurons, power stations or lasers — will behave collectively, given their individual dynamics and coupling architecture.

Self-organized criticality: An explanation of the 1/ f noise
TL;DR: It is shown that dynamical systems with spatial degrees of freedom naturally evolve into a self-organized critical point, and flicker noise, or 1/f noise, can be identified with the dynamics of the critical state.

EEG alpha and theta oscillations reflect cognitive and memory performance: a review and analysis
TL;DR: In this article, it is suggested to adjust the frequency windows of alpha and theta for each subject by using individual alpha frequency as an anchor point, based on this procedure, a consistent interpretation of a variety of findings is made possible.
