Corticopetal Acetylcholine: Possible Scenarios on the Role for Dynamic Organization of Quasi-Attractors
TLDR
The corticopetal ACh helps to transiently organize a global (inter- and intra-cortical) quasi-attractors via gamma range synchrony when it is behaviorally needed as top-down attentions and expectation.

Recently, neural oscillations, especially gamma oscillation (>30 Hz) has been paid attention in the Systems Neuroscience. In monkey, neural oscillations are involved in either intrahemispheric or…

Cognitive Consilience: Primate Non-Primary Neuroanatomical Circuits Underlying Cognition
TLDR
This work focuses on neuroanatomy related to primate non-primary cortical systems to elucidate the basis underlying the distinct homotypical cognitive architecture and introduces a novel method of integrating and presenting data in multiple independent visualizations.
Electrophysiological Evidence for Spatiotemporal Flexibility in the Ventrolateral Attention Network
TLDR
It is found that the subregions that comprise the reflexive ventrolateral attention network dissociate both spatially and temporally as a function of the nature of the sensory information and current task demands.
Impulse Propagation along Thalamocortical Fibers Can Be Detected Magnetically outside the Human Brain
TLDR
It is argued that the MEG technique holds the promise of providing novel information in impulse transmissions along not only the thalamocortical pathway but also other fiber tracts connecting distant brain areas in humans.

TLDR
The brain is proposed as an isoenergetic structure having little energy barriers that limit the distribution of neuronal information, thereby facilitating unitary brain functioning and enabling efficient coordination of neural activities, thus facilitating fast access to memory.

A Framework for Understanding the Emerging Role of Corticolimbic-Ventral Striatal Networks in OCD-Associated Repetitive Behaviors
TLDR
This work addresses the emerging role of medial OFC, amygdala, and ventral tegmental area projections to the ventral striatum (VS) in OCD pathophysiology and discusses this network’s potential role as a locus of OCD pathology and effective treatment.

Modulation of Neuronal Interactions Through Neuronal Synchronization
TLDR
It is proposed that the pattern of synchronization flexibly determines thepattern of neuronal interactions, and that the mutual influence among neuronal groups depends on the phase relation between rhythmic activities within the groups.
Neuronal Oscillations in Cortical Networks
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.
Prefrontal modulation of visual processing in humans
TLDR
This work provides anatomical, electrophysiological and behavioral evidence that prefrontal cortex regulates neuronal activity in extrastriate cortex during visual discrimination and provides evidence for intrahemispheric prefrontal modulation of visual processing.
High Gamma Power Is Phase-Locked to Theta Oscillations in Human Neocortex
TLDR
The results indicate that transient coupling between low- and high-frequency brain rhythms coordinates activity in distributed cortical areas, providing a mechanism for effective communication during cognitive processing in humans.
Typologies of attentional networks
TLDR
Given the recent explosion in empirical data, attentional typologies provide powerful conceptual tools with which to contextualize and integrate these findings.
Brain Oscillations Control Timing of Single-Neuron Activity in Humans
TLDR
Recording from 1924 neurons indicates that theta and delta oscillations facilitate phase coding and that gamma oscillations help to decode combinations of simultaneously active neurons, providing support for the temporal-coding hypothesis in humans.
Storage of 7 +/- 2 short-term memories in oscillatory subcycles
TLDR
It is shown that activity patterns associated with multiple memories can be stored in a single neural network that exhibits nested oscillations similar to those recorded from the brain.
Neural Mechanisms of Visual Attention: How Top-Down Feedback Highlights Relevant Locations
TLDR
Parietal neurons may selectively increase activity in earlier sensory areas to enable focused spatial attention in monkeys performing a visual matching task.
Top-Down Versus Bottom-Up Control of Attention in the Prefrontal and Posterior Parietal Cortices
TLDR
The result indicates that top-down and bottom-up signals arise from the frontal and sensory cortex, respectively, and different modes of attention may emphasize synchrony at different frequencies.
