TLDR
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

Collective oscillations in disordered neural networks
TL;DR: The onset of collective oscillations in a excitatory pulse-coupled network of leaky integrate-and-fire neurons in the presence of quenched and annealed disorder induces a weak form of chaos that is analogous to that arising in the Kuramoto model for a finite number of oscillators.

TL;DR: The collapse of pyramidal cell perisomatic inhibition appears to be a crucial factor in the emergence of epileptiform events in the mouse hippocampus.

TL;DR: It is found that polypyrrole-CNT coating significantly reduced the microelectrode impedance at all neuronal signal frequencies and induced a significant improvement of the SNR, up to fourfold on average, in the 150-1500 Hz frequency range, largely corresponding to the multiunit frequency band.

A Unified Dynamic Model for Learning, Replay, and Sharp-Wave/Ripples.
TL;DR: A unified model is presented showing how experience may be stored and thereafter replayed in association with sharp-wave/ripple complexes and it is proposed that replay and SPW/Rs are tightly interconnected as they mutually generate and support each other.

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.
