We have demonstrated previously that neurons in cat striate cortex, in response to their preferred stimuli, exhibit oscillatory responses in a frequency range of 40–60 Hz. Recently, we obtained evidence that such oscillatory responses can synchronize across columns. We have now performed an extensive analysis of this phenomenon for both unit and field potential responses. In addition, we studied the stimulus conditions leading to intercolumnar synchronization. We recorded both multi‐unit… 

Squint Affects Synchronization of Oscillatory Responses in Cat Visual Cortex

The results support the notion that response synchronization is achieved by cortico‐cortical connections and serves as a mechanism for feature binding in the visual cortex of strabismic cats.

Stimulus‐Dependent Neuronal Oscillations in Cat Visual Cortex: Receptive Field Properties and Feature Dependence

Functional heterogeneity among cells within striate cortex based on their temporal firing patterns is demonstrated and evidence that the temporal pattern of oscillatory cellular activity is influenced by changes in stimulus properties is provided.

Synchronization of oscillatory neuronal responses in cat striate cortex: Temporal properties

A new analysis reveals a high degree of dynamic variability and a rapid onset and offset of synchrony among interacting populations of neurons which is consistent with the requirements of a mechanism for feature integration.

The response of cat visual cortex to flicker stimuli of variable frequency

The results suggest that the retino‐cortical system contains broadly tuned, strongly damped oscillators which altogether exhibit at least three ranges of preferred frequencies, the relative expression of the preferences depending on the central state.

Stimulus-dependent modulations of correlated high-frequency oscillations in cat visual cortex.

It is concluded that correlated neural activity is a potential candidate for coding of sensory information in the cortical representation of visual stimuli.

Synchronous High‐frequency Oscillations in Cat Area 18

The findings suggest that correlated oscillatory activity provides a potential neural code supporting sensory information processing in anaesthetized cats.

Functional coupling shows stronger stimulus dependency for fast oscillations than for low‐frequency components in striate cortex of awake monkey

Spectral coherence among pairs of signals recorded in the striate cortex of awake monkeys indicates that different frequency components can engage different coupling networks in the Striate cortex which probably support different coding tasks.

Synchronization Dynamics in Response to Plaid Stimuli in Monkey V1

The results suggest that the functional architecture of the cortex is a major determinant of the neuronal synchronization dynamics in V1, and may be that single gratings induce strong cooperative interactions among populations of cells that share similar response properties, whereas plaids lead to competition.

Relationship between spontaneous and evoked spike-time correlations in primate visual cortex.

Recordings from primary visual cortex of the anesthetized and paralyzed prosimian bush baby suggest that spike-time correlations present in evoked activity are generated by mechanisms common to those operating in spontaneous conditions.

Stimulus-Dependent Assembly Formation of Oscillatory Responses: II. Desynchronization

It is shown that appropriately designed excitatory delay connections can support the desynchronization of two-dimensional layers of delayed nonlinear oscillators and that the coherence of movement and location of two stimulus bar segments can be coded by the correlation of oscillatory activity.



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.

The results demonstrate that local neuronal populations in the visual cortex engage in stimulus-specific synchronous oscillations resulting from an intracortical mechanism, and may provide a general mechanism by which activity patterns in spatially separate regions of the cortex are temporally coordinated.

Relationships between horizontal interactions and functional architecture in cat striate cortex as revealed by cross-correlation analysis

Cross-correlation analysis in cat striate cortex found a tendency for facilitatory interactions between cells sharing the same eye preference and a high degree of interconnectivity between and within the columns.

Form, function and intracortical projections of spiny neurones in the striate visual cortex of the cat.

The neuronal circuitry and structure‐function relationships of single neurones in the striate visual cortex of the cat using a combination of electrophysiological and anatomical techniques were studied and two striking correlations were found between dendritic morphology and receptive field type.

It is found that individual neurons in the cat primary visual cortex can communicate over suprisingly long distances horizontally, in directions parallel to the cortical surface, by combining the techniques of intracellular recording and injection of horseradish peroxidase with three- dimensional computer graphic reconstructions.

Inhibition contributes to orientation selectivity in visual cortex of cat

Using cross-correlation analysis of the activities of two neurons recorded simultaneously, it is found that inhibitory interactions exist between cells with somewhat different, but not orthogonal, orientation preferences, which suggests that intracortical horizontal inhibition operates between 'orientation columns' to sharpen the orientation tuning of cortical neurons.

The cytochrome oxidase-rich patches or blobs of the monkey striate cortex have been shown to contain cells that have unoriented receptive fields, many of which are color selective. We studied the
