TL;DR

The neural mechanisms of visual binding in humans were investigated by measuring the brain's high-frequency electric responses to the subjective visual perception of a unified three-dimensional illusion and 40 Hz synchronization was found over occipital and right parieto-temporal areas.

Abstract

The neural mechanisms of visual binding in humans were investigated by measuring the brain's high-frequency electric responses (36-44 Hz) to the subjective visual perception of a unified three-dimensional illusion. 40 Hz synchronization was found over occipital and right parieto-temporal areas 500-300 ms before visual awareness of the three-dimensional Gestalt was reported, but not during the viewing of the illusion. At lower frequency bands (8-13 Hz and 13-20 Hz) no corresponding synchronization was found. 40 Hz synchronization thus directly correlates with the construction and emergence of a unified visual percept and may reflect the rapid formation of transient functional connections between spatially separated cortical areas.

Neuroscience

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

4,261 Citations1989Charles M. Gray, Peter König +2 more

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.

CognitionTime-locked multiregional retroactivation: A systems-level proposal for the neural substrates of recall and recognition

1,529 Citations1989António R. Damásio

This proposal rejects a single anatomical site for the integration of memory and motor processes and a single store for the meaning of entities of events and proposes an architecture constituted by neuron ensembles located in multiple and separate regions of primary and first-order sensory association cortices.

Current Opinion in NeurobiologyThe binding problem

1,134 Citations1996Anne Treisman

Deficits in neurological patients suggest a role for the parietal cortex in the binding process ofceptual representations, which depend on distributed neural codes for relaying the parts and properties of objects.

Electroencephalography and Clinical NeurophysiologyEvent-related synchronization (ERS): an electrophysiological correlate of cortical areas at rest

983 Citations1992G. Pfurtscheller

It was found that alpha band activity can be enhanced over the visual region during a motor task, or during a visual task over the sensorimotor region, which means ERD and ERS can be observed at nearly the same time.

Brain Research ReviewsLarge-scale cortical networks and cognition

562 Citations1995Steven L. Bressler

A substantial body of evidence is examined supporting the view that complex integrative functions are carried out by large-scale networks of cortical areas, and the functional topology of a large- scale cortical network is dynamically reorganized during visuomotor behavior.

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.

NeuroreportSimultaneous EEG 10 Hz desynchronization and 40 Hz synchronization during finger movements

213 Citations1992Gert Pfurtscheller, Christa Neuper

The EEG was analysed in the 10 Hz band and in four 40 Hz bands by calculation of ERD time courses and ERD maps, whereby a ERD is characterized by a movement-related band power decrease, and a close to C3 localized 10 Hz ERD was found.

Current Opinion in NeurobiologyTowards the neuronal correlate of visual awareness

71 Citations1996Christof Koch, Jochen Braun

Results suggest that the contents of visual awareness reflect neuronal activity in certain extrastriate, but not in striate, visual cortical areas.
