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… 

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 of

Synchronization of Neuronal Activity during Stimulus Expectation in a Direction Discrimination Task

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

Dynamics of striate cortical activity in the alert macaque: II. Fast time scale synchronization.

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.

Synchronization and assembly formation in the visual cortex.

Control of Functional Connectivity in Cerebral Cortex by Basal Ganglia Mediated Synchronization

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.

Synchronization between temporal and parietal cortex during multimodal object processing in man.

Evidence that population activity of temporal cortex and parietal cortex shows enhanced coherence during presentation of semantic entities is provided and coherent activity in this low-frequency range might play a role for binding of multimodal ensembles.

High-Frequency, Long-Range Coupling Between Prefrontal and Visual Cortex During Attention

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.



The Role of Neuronal Synchronization in Response Selection: A Biologically Plausible Theory of Structured Representations in the Visual Cortex

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.

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.

Episodic multiregional cortical coherence at multiple frequencies during visual task performance

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.

Interhemispheric synchronization of oscillatory neuronal responses in cat visual cortex

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.

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.

Oscillatory responses in cat visual cortex exhibit inter-columnar synchronization which reflects global stimulus properties

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.

Spatial and temporal coherence in cortico-cortical connections: A cross-correlation study in areas 17 and 18 in the cat

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 to produce each of the three different degrees of observed spatial and temporal coherence are suggested.

Distributed hierarchical processing in the primate cerebral cortex.

A summary of the layout of cortical areas associated with vision and with other modalities, a computerized database for storing and representing large amounts of information on connectivity patterns, and the application of these data to the analysis of hierarchical organization of the cerebral cortex are reported on.

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.
