INFORMATION processing in the cerebral cortex invariably involves the activation of millions of neurons that are widely distributed over its various areas. These distributed activity patterns need to be integrated into coherent representational states. A candidate mechanism for the integration and coordination of neuronal activity between different brain regions is synchronization on a fine temporal scale1–3. In the visual cortex, synchronization occurs selectively between the responses of… Expand
Response Synchronization, Gamma Oscillations, and Perceptual Binding in Cat Primary Visual Cortex
Publisher Summary This chapter examines the extent to which current concepts about the nature of cortical codes and representations can be generalized to striate cortex functions. The functions ofExpand
Integrative visuomotor behavior is associated with interregionally coherent oscillations in the human brain.
Coherent electrical brain activity has been demonstrated to be associated with perceptual events in mammals. It is unclear whether or not it is also a mechanism instrumental in the performance ofExpand
Synchronization of Neuronal Activity during Stimulus Expectation in a Direction Discrimination Task
TLDR
It is concluded that under the conditions of this study, temporal decorrelation of MT and MST neurons could be used to detect the stimulus, but synchronization does not convey specific information about its direction of motion and therefore is unlikely to contribute to performance in the authors' direction discrimination task.

Zero-lag synchronous dynamics in triplets of interconnected cortical areas
TLDR
This work shows through detailed computer simulations that, when triplets rather than pairs of reciprocally connected areas in a cortical hierarchy are considered, zero-lag synchronization emerges naturally from their three-way interactions. Expand
Precise spike synchronization in monkey motor cortex involved in preparation for movement
TLDR
The findings indicate that the synchronization of individual action potentials and the modulation of the firing rate may serve different and complementary functions underlying the cortical organization of cognitive motor processes. Expand
Dynamics of striate cortical activity in the alert macaque: II. Fast time scale synchronization.
TLDR
It is found that neuronal synchronization with millisecond precision is a prevalent and robust feature of stimulus-evoked activity in striate cortex and suggests that neuronal rhythmicity is an important mechanism contributing to synchronization. Expand
Synchronization and assembly formation in the visual cortex.
TLDR
The experimental findings demonstrating that distributed neural populations in the visual cortex process information in a cooperative way are described, with evidence accumulated that temporal relations among the responses of concurrently activated neurons convey information, which is unavailable from the single-cell responses alone. Expand
High-Frequency, Long-Range Coupling Between Prefrontal and Visual Cortex During Attention
TLDR
It is found that attention to a stimulus in their joint receptive field leads to enhanced oscillatory coupling between the two areas, particularly at gamma frequencies, which may optimize the postsynaptic impact of spikes from one area upon the other, improving cross-area communication with attention.

Control of Functional Connectivity in Cerebral Cortex by Basal Ganglia Mediated Synchronization
TLDR
The basal ganglia mediated synchronization model, introduced here, implicates these oscillations in the combination of cortical association mechanisms with stimulus-response and reinforcement mechanisms in the basal gangs, and facilitates and synchronizes activity in selected areas of cortex.

Temporal coding in the visual cortex: new vistas on integration in the nervous system
TLDR
These results support the hypothesis that temporal correlation of neuronal discharges may serve to bind distributed neuronal activity into unique representations and indicate that neuronal responses with an oscillatory temporal structure may be particularly advantageous as carrier signals for such a temporal coding mechanism.

The Role of Neuronal Synchronization in Response Selection: A Biologically Plausible Theory of Structured Representations in the Visual Cortex
TLDR
Theoretical arguments and predictions concerning the mechanisms that could group neurons responding to related image components into coherently active aggregates are presented and it is proposed that the range of synchronizing interactions is a dynamic parameter of the cortical network so that the grain of the resultant grouping process may be adapted to the actual behavioral requirements.

Synchronization of oscillatory neuronal responses between striate and extrastriate visual cortical areas of the cat.
TLDR
It is demonstrated that unit responses recorded from the posteromedial lateral suprasylvian area, a visual association area specialized for the analysis of motion, also exhibit an oscillatory temporal structure, supporting the hypothesis that synchronous neuronal oscillations may serve to establish relationships between features processed in different areas of visual cortex.

Episodes of increased broad-band coherence among local field potentials from sensory, motor and higher-order cortical sites of macaque monkeys performing a visual discrimination task are described. Expand
Interhemispheric synchronization of oscillatory neuronal responses in cat visual cortex
TLDR
Response synchronization has now been shown to occur also between neurons in area 17 of the right and left cerebral hemispheres, and this synchronization is mediated by corticocortical connections, compatible with the hypothesis that temporal synchrony of neuronal discharges serves to bind features within and between the visual hemifields.

Stimulus-specific fast oscillations at zero phase between visual areas V1 and V2 of awake monkey.
TLDR
The presence of, and phase-locking between, high amplitude stimulus specific oscillations in striate and extra striate visual cortex of an awake monkey demonstrates the presence of near zero-phase synchronization among cortical areas that might enable fast and effective communication via the many reciprocal cortico-cortical connections. Expand
Oscillatory responses in cat visual cortex exhibit inter-columnar synchronization which reflects global stimulus properties
TLDR
It is demonstrated here that neurons in spatially separate columns can synchronize their oscillatory responses, which has, on average, no phase difference, depends on the spatial separation and the orientation preference of the cells and is influenced by global stimulus properties. Expand
Spatial and temporal coherence in cortico-cortical connections: a cross-correlation study in areas 17 and 18 in the cat.
TLDR
It is suggested that distributed common-input cell assemblies are a means of overcoming sparse connectivity and achieving synaptic transmission in the pyramidal network and three different mechanisms are suggested to produce each of the three different degrees of observed spatial and temporal coherence.

Dynamics of neuronal interactions in monkey cortex in relation to behavioural events
TLDR
It is shown that correlated firing between single neurons, recorded simultaneously in the frontal cortex of monkeys performing a behavioural task, evolves within a fraction of a second, and in systematic relation to behavioural events, support the notion that neurons can associate rapidly into a functional group in order to perform a computational task, at the same time becoming dissociated from concurrently activated competing groups.
