The brain's default state: self-organized oscillations in rest and sleep, and perturbation of the default patterns by experience.Abstract:
Prelude. Cycle 1. Introduction. Cycle 2. Structure defines function. Cycle 3. Diversity of cortical functions is provided by inhibition. Cycle 4. Windows on the brain. Cycle 5. A system of rhythms: from simple to complex dynamics. Cycle 6. Synchronization by oscillation. Cycle 7. The brain's default state: self-organized oscillations in rest and sleep. Cycle 8. Perturbation of the default patterns by experience. Cycle 9. The gamma buzz: gluing by oscillations in the waking brain. Cycle 10. Perceptions and actions are brain state-dependent. Cycle 11. Oscillations in the "other cortex:" navigation in real and memory space. Cycle 12. Coupling of systems by oscillations. Cycle 13. The tough problem. References.read more

Distinct Beta-band Oscillatory Circuits Underlie Corticospinal Gain Modulation.
TL;DR: Novel evidence that intrinsic activity in the human motor cortex modulates input gain along the beta oscillatory cycle within distinct circuits is provided, which may lead to new brain state-dependent and circuit-specific interventions for targeted neuromodulation.

A new perspective on behavioral inconsistency and neural noise in aging: compensatory speeding of neural communication.
S. Lee Hong,George V. Rebec +1 more
TL;DR: This perspective proposes the possibility that the slowing of neural processing due to decreasing nerve conduction velocities leads to a compensatory speeding of neuron firing rates, which lead to a broader distribution of power in the frequency spectrum of neural oscillations.

Regulating Cortical Oscillations in an Inhibition-Stabilized Network
TL;DR: Oscillations in the model grow stronger as the mean firing level is reduced, accounting for the size dependence of visually evoked gamma rhythms, and suggesting a role for oscillations in improving the signal-to-noise ratio (SNR) of signals in the brain.

Macroscopic Phase Resetting-Curves Determine Oscillatory Coherence and Signal Transfer in Inter-Coupled Neural Circuits
TL;DR: A causal theory for oscillatory modulation of functional connectivity between cortical circuits is suggested and shows that symmetry-broken coherence states can lead to a preferred direction of signal transfer between the oscillatory networks where this directionality also depends on the timing of the signal.

Stimulus-induced visual cortical networks are recapitulated by spontaneous local and interareal synchronization
Christopher M. Lewis,Christopher M. Lewis,Conrado A. Bosman,Conrado A. Bosman,Thilo Womelsdorf,Pascal Fries,Pascal Fries +6 more
TL;DR: The results suggest that networks of intrinsic covariation observed at multiple levels and with several recording techniques are related to synchronization and that behavioral state may affect the structure of intrinsic dynamics.

Collective dynamics of small-world networks
TL;DR: Simple models of networks that can be tuned through this middle ground: regular networks ‘rewired’ to introduce increasing amounts of disorder are explored, finding that these systems can be highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs.

The Fractal Geometry of Nature
TL;DR: This book is a blend of erudition, popularization, and exposition, and the illustrations include many superb examples of computer graphics that are works of art in their own right.

The magical number seven, plus or minus two: some limits on our capacity for processing information
TL;DR: The theory of information as discussed by the authors provides a yardstick for calibrating our stimulus materials and for measuring the performance of our subjects and provides a quantitative way of getting at some of these questions.

The relation of strength of stimulus to rapidity of habit-formation
Robert M. Yerkes,John D. Dodson +1 more
TL;DR: In connection with a study of various aspects of the modifiability of behavior in the dancing mouse a need for definite knowledge concerning the relation of strength of stimulus to rate of learning arose, the experiments which are now to be described arose.

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.
