Beta oscillations observed in motor cortical local field potentials (LFPs) recorded on separate electrodes of a multi-electrode array have been shown to exhibit non-zero phase shifts that organize into planar waves. Here, we generalize this concept to additional classes of salient patterns that fully describe the spatial organization of beta oscillations. During a delayed reach-to-grasp task we distinguish planar, synchronized, random, circular, and radial phase patterns in monkey primary motor… 
Beta oscillations and waves in motor cortex can be accounted for by the interplay of spatially-structured connectivity and fluctuating inputs
TLDR
A simple model of motor cortex based on local excitatory-inhibitory neuronal populations coupled by longer range excitation, where additionally inputs to the motor cortex from other neural structures are represented by stochastic inputs on the different model populations is proposed.
Spatiotemporal organization of human sensorimotor beta burst activity
TLDR
It is shown in human magnetoencephalography recordings that burst activity in sensorimotor cortex occurs in planar spatiotemporal wave-like patterns that dominate along two axes either parallel or perpendicular to the central sulcus, and that the two propagation directions are characterised by distinct anatomical and physiological features.
Is there an Intrinsic Relationship between LFP Beta Oscillation Amplitude and Firing Rate of Individual Neurons in Macaque Motor Cortex?
TLDR
There is no intrinsic relationship between the firing rate of individual neurons and LFP beta oscillation amplitude in macaque motor cortex, according to quantified correlation between beta amplitude and neuronal spike count during visuomotor behavior.
Synchronization, stochasticity and phase waves in neuronal networks with spatially-structured connectivity
TLDR
Stochastic dephasing of neighboring modules produces transient phase gradients and the transient appearance of phase waves that provide an explanative framework for the observations of traveling waves in the cortex during beta oscillations.
Spontaneous neuronal oscillations in the human insula are hierarchically organized traveling waves
TLDR
Human intracranial electroencephalographic recordings are used to investigate the electrophysiological properties and hierarchical organization of spontaneous neuronal oscillations within the insula and find that rhythms in the theta and beta frequency oscillations are widespread and spontaneously present.
Synchronization, Stochasticity, and Phase Waves in Neuronal Networks With Spatially-Structured Connectivity
TLDR
Stochastic dephasing of neighboring modules produces transient phase gradients and the transient appearance of phase waves that provide an explanative framework for the observations of traveling waves in the cortex during beta oscillations.
Reconciliation of weak pairwise spike-train correlations and highly coherent local field potentials across space
TLDR
Based on model predictions of spiking activity and LFPs, it is found that the upscaling procedure preserves the overall spiking statistics of the original model and reproduces asynchronous irregular spiking across populations and weak pairwise spike-train correlations observed in sensory cortex.
1024-channel electrophysiological recordings in macaque V1 and V4 during resting state
TLDR
This paper carried out electrophysiological recordings from over a thousand chronically implanted electrodes in the visual cortex of non-human primates, yielding a resting state dataset with unprecedentedly high channel counts and spatiotemporal resolution.

Emergence of Complex Wave Patterns in Primate Cerebral Cortex
TLDR
It is shown that nerve cell spike rates are higher in presence of complex waves than in the presence of synchrony and that there are nonrandom patterns of evolution from one type of complex wave to another.
Context-related frequency modulations of macaque motor cortical LFP beta oscillations.
TLDR
Multiple beta bands coexist in motor cortex, and frequency modulations within each band are as behaviorally meaningful as power modulations, reflecting the changing behavioral context and the movement direction during preparation.
Propagating waves mediate information transfer in the motor cortex
TLDR
It is found that information about the visual target to be reached was encoded in terms of both latency and amplitude of evoked waves at a time when the field phase-locked with respect to the target onset.
Synchronization of neurons during local field potential oscillations in sensorimotor cortex of awake monkeys.
TLDR
The neural activity associated with 20- to 40-Hz oscillations in sensorimotor cortex of awake monkeys was investigated by recording action potentials of single and multiple units to suggest units across wide regions can become transiently synchronized specifically during LFP oscillations.
Bursts of beta oscillation differentiate postperformance activity in the striatum and motor cortex of monkeys performing movement tasks
TLDR
It is shown that brief bursts of oscillation are responsible for virtually all beta-band activity in healthy monkeys, and it is suggested that the timing and duration of these bursts are critical parameters for network function.

TLDR
Synchronous 25- to 35-Hz oscillations were observed in local field potentials and unit activity in sensorimotor cortex of awake rhesus monkeys, suggesting that such oscillations may facilitate interactions between cells during exploratory and manipulative movements, requiring attention to sensorsimotor integration.
Temporal structure in neuronal activity during working memory in macaque parietal cortex
TLDR
The temporal structure of local field potential activity and spiking from area LIP in two awake macaques during a memory-saccade task was studied and it was found that LFP activity in parietal cortex discriminated between preferred and anti-preferred direction with approximately the same accuracy as the spike rate.
The Local Field Potential Reflects Surplus Spike Synchrony
TLDR
Experimental evidence is presented to reconcile the notions of synchrony at the level of spiking and at the mesoscopic scale and shows that only in time intervals of significant spike synchrony that cannot be explained on the basis of firing rates, coincident spikes are better phase locked to the LFP than predicted by the locking of the individual spikes.
Mapping the spatio-temporal structure of motor cortical LFP and spiking activities during reach-to-grasp movements
TLDR
Analysis of massively parallel signals from population measures and single neuron spiking activities recorded simultaneously during a delayed reach-to-grasp task shows that, in motor cortex, a precise spatio-temporal pattern of activation is involved for the control of reach- to-Grasp movements and provides some new insight about the functional organization of motor cortex during reaching and object manipulation.
