The Unconscious Mind
This chapter describes recent evidence that there is a limit of consciousness that presents a barrier between conscious and unconscious processes. The barrier is likely specifically related to
Modeling the Neural Basis of Cognitive Integration and Consciousness
A number of models are presented whose aim is to establish a computational basis for the hypothesis that conscious information processing in the brain is mediated by a mechanism of global broadcast.
Biology of Consciousness
The constraints on causal analyses of consciousness are examined and it is suggested that there is now sufficient evidence to consider the design and construction of a conscious artifact.
Consciousness: Theories and Models
How conscious experience and working memory interact
Do consciousness and attention have shared neural correlates
Some of the most relevant theoretical issues surrounding the concepts of consciousness and attention in the neuroscientific literature are reviewed, and the implications of these reflections for a coherent model of the neural correlates of these cognitive functions are presented.
Consciousness and Complexity

Applying measures of neural integration and complexity, together with an analysis of extensive neurological data, leads to a testable proposal-the dynamic core hypothesis-about the properties of the neural substrate of consciousness.


Temporal binding and the neural correlates of sensory awareness
Some Essential Differences between Consciousness and Attention, Perception, and Working Memory

The term "attention" may be best applied to the selection and maintenance of conscious contents and distinguished from consciousness itself, and is applied to Posner's (1994) brain model of visual attention.
Towards a cognitive neuroscience of consciousness: basic evidence and a workspace framework
A Neural Attentional Model for Access to Consciousness: A Global Workspace Perspective
An explication of the role of this "neural global workspace" in providing the essential basis for the central control of attention and the generation of unified, conscious percepts is explication.

The neuronal basis for consciousness.
The goal of this paper is to explore the basic assumption that large-scale, temporal coincidence of specific and non-specific thalamic activity generates the functional states that characterize human cognition.

The brainweb: Phase synchronization and large-scale integration
It is argued that the most plausible candidate is the formation of dynamic links mediated by synchrony over multiple frequency bands.

The author applied the common-sense distinction between attention and consciousness to the theoretical positions of M. Posner (1992, 1994) and D. LaBerge (1997, 1998) to show how it helps to clarify the evidence and concluded that clarity of thought is served by calling a thing by its proper name.
