Theories of binding have recently come into the focus of the consciousness debate. In this review, we discuss the potential relevance of temporal binding mechanisms for sensory awareness. Specifically, we suggest that neural synchrony with a precision in the millisecond range may be crucial for conscious processing, and may be involved in arousal, perceptual integration, attentional selection and working memory. Recent evidence from both animal and human studies demonstrates that specific… Expand

Neural correlates of consciousness in humans
TLDR
Functional neuroimaging in humans and electrophysiology in awake mokeys indicate that there are important differences between striate and extrastriate visual cortex in how well neural activity correlates with consciousness. Expand
The Neural Basis of Perceptual Awareness
An understanding of the neural basis of perceptual awareness requires solving two problems. First, the brain mechanisms that regulate access to conscious perceptual experience need to be identified.Expand
Neuronal Oscillations, Coherence, and Consciousness
Evidence accumulated in the past two decades strongly suggests that synchronization of oscillatory neural signals is one of the key mechanisms for integrating and selecting information in distributedExpand
Auditory Awareness Due to Synchronous Neural Activity in Inferior Colliculus of Awake Cats
The previous report on the dynamics of spontaneous and evoked activities of the neural net within the cat inferior colliculus (IC) has been extended in relation to today's issues in the study ofExpand
Temporal dynamics of access to consciousness in the attentional blink
TLDR
It is concluded that the resources allocated to first and second target processing are directly mirrored by the P3 component and, moreover, that brain states before and during stimulus presentation, as reflected by oscillatory brain activity, strongly determine the access to consciousness. Expand
Oscillatory synchrony as a mechanism of attentional processing
TLDR
Findings suggest that oscillatory synchrony in specific frequencies reflects the biophysical properties of specific cell types and local circuits and allows the brain to dynamically switch between different spatio-temporal patterns of activity to achieve flexible integration and selective routing of information along selected neuronal populations according to behavioral demands. Expand
Dynamic predictions: Oscillations and synchrony in top–down processing
TLDR
It is argued that coherence among subthreshold membrane potential fluctuations could be exploited to express selective functional relationships during states of expectancy or attention, and these dynamic patterns could allow the grouping and selection of distributed neuronal responses for further processing.

I propose that primary conscious awareness arises from synchronized activity in dendrites of neurons in dorsal thalamic nuclei, mediated particularly by inhibitory interactions with thalamicExpand
The conscious access hypothesis: origins and recent evidence
  • B. Baars
  • Medicine, Psychology

TLDR
Recent neuroimaging evidence appears broadly to support the 'conscious access hypothesis', which has implications for perception, learning, working memory, voluntary control, attention and self systems in the brain. Expand
Binding Mechanisms in Visual Perception and Their Link With Neural Oscillations: A Review of Evidence From tACS
TLDR
Overall, the emerging picture seems to support a causal role of brain oscillations in binding processes and, consequently, a certain degree of plasticity for shaping binding mechanisms in visual perception, which, if proved to have long lasting effects, can find applications in different clinical populations.

Temporal Binding, Binocular Rivalry, and Consciousness
TLDR
The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. Expand
Neural correlates of visual and motor decision processes
TLDR
Whereas perceptual processing occupies a relatively constant amount of time for a given stimulus condition, the processes of mapping particular stimuli onto the appropriate behavior and preparing the motor response provide flexibility but introduce delay and variability in reaction time. Expand
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. Expand
Synchronization between prefrontal and posterior association cortex during human working memory.
TLDR
The results suggest that working memory involves synchronization between prefrontal and posterior association cortex by phase-locked, low frequency (4-7 Hz) brain activity. 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.

Conventional approaches to understanding consciousness are generally concerned with the contribution of specific brain areas or groups of neurons. By contrast, it is considered here what kinds ofExpand

During aroused states of the brain, electroencephalographic activity is characterized by fast, irregular fluctuations of low amplitude, which are thought to reflect desynchronization of neuronalExpand

TLDR
It is suggested that sensory and cognitive processing in the What processing stream of the brain obey top-down matching and learning laws that are often complementary to those used for spatial and motorprocessing in the brain's Where processing stream, which enables their sensory and Cognitive representations to maintain their stability as the authors learn more about the world.

Oscillatory activity is not evident in the primate temporal visual cortex with static stimuli
TLDR
It is put forward the possibility that temporal synchronization between neurons to implement binding may not be generally used in the visual system as a solution to the binding problem, at least when static objects are being processed and recognised in higher parts of theVisual system. Expand
From perception to action: temporal integrative functions of prefrontal and parietal neurons.
TLDR
A visuomotor task that dissociated the perceptual and executive aspects of the perception-action cycle in both space and time provides physiological evidence for the role of a prefrontal-parietal network in the integration of perception with action across time. Expand
