This introductory chapter attempts to clarify the philosophical, empirical, and theoretical bases on which a cognitive neuroscience approach to consciousness can be founded. We isolate three major empirical observations that any theory of consciousness should incorporate, namely (1) a considerable amount of processing is possible without consciousness, (2) attention is a prerequisite of consciousness, and (3) consciousness is required for some specific cognitive tasks, including those that… Expand
Information generation as a functional basis of consciousness
TLDR
It is argued that the ability to generate information underlies a variety of cognitive functions associated with consciousness such as intention, imagination, planning, short-term memory, attention, curiosity, and creativity, all of which contribute to non-reflexive behavior. Expand
Information Generation as a Functional Basis of Consciousness
What is the biological advantage of having consciousness? Functions of consciousness have been elusive due to the subjective nature of consciousness and ample empirical evidence showing the presenceExpand
Representation Internal-Manipulation (RIM): A Neuro-Inspired Computational Theory of Consciousness
TLDR
The Representation Internal-Manipulation (RIM) theory of consciousness is proposed, a theory that links the main elements of consciousness theories to components and functions of goal-directed behaviour, ascribing a central role for consciousness to the goal- directed manipulation of internal representations. Expand
CONSCIOUSNESS IS COMPUTATIONAL: THE LIDA MODEL OF GLOBAL WORKSPACE THEORY
TLDR
It is argued that the functions of consciousness are implemented in a bio-computational manner, and it is proposed that machine consciousness may be produced by similar adaptive algorithms running on the machine. Expand
What are the computational correlates of consciousness
Abstract Cognitive phenomenology refers to the idea that our subjective experiences include deliberative thought processes and high-level cognition. The recent ascendance of cognitive phenomenologyExpand
The Endogenous Feedback Network: A new approach to the comprehensive study of consciousness
TLDR
A new theory, the Endogenous Feedback Network (EFN) will be introduced which, besides being able to accommodate the main tenets of the reviewed theories, appears able to compensate for the explanatory gaps they leave behind. Expand
An adaptive workspace hypothesis about the neural correlates of consciousness: insights from neuroscience and meditation studies.
TLDR
This paper advances an adaptive workspace hypothesis about the NCC based on the global workspace model emphasizing transient resonant neurodynamics and prefrontal cortex function, as well as meditation-related characterizations of conscious experiences, and develops a unitary theoretical framework for NCC. Expand
Mathematics and the Brain: A Category Theoretical Approach to Go Beyond the Neural Correlates of Consciousness
TLDR
It is concluded that CT, especially the application of the notion of natural transformation, highlights that the authors need to go beyond NCC and unravels questions that need to be addressed by any future neuroscientific theory of consciousness. Expand
Distilling the neural correlates of consciousness
TLDR
Evidence supporting conjecture that the NCC proper can be confounded with prerequisites for and consequences of conscious processing of the particular content is reviewed and experimental strategies to untangle it are suggested in order to further develop the otherwise valid and valuable contrastive methodology. Expand
Concepts, contents, and consciousness
TLDR
It is argued that there are a number of respects in which the contrast between conservative and liberal conceptions of the admissible contents of consciousness is more complex than Kemmerer’s discussion suggests. Expand

The neural correlates of conscious experience: an experimental framework
TLDR
It remains to be seen whether the neural signature of consciousness relates to the location of the neural activity, the temporal properties of the Neural Signature of consciousness or the form of the interaction between activity in different brain regions. Expand

A neuronal model of a global workspace in effortful cognitive tasks.
TLDR
A minimal hypothesis is proposed concerning the brain processes underlying effortful tasks and predictions for spatio-temporal activation patterns during brain imaging are outlined, particularly about the contribution of dorsolateral cortex and anterior cingulate to the workspace. Expand

Topography of cognition: parallel distributed networks in primate association cortex.
TLDR
The structure and functions of the frontal lobes, particularly the prefrontal "silent" portion, have recently again become the subject of intense interest and the availability of solid new findings in experimental animals and human patients and the promise of further discoveries are undoubtedly the basis of this renewed interest.

Memory, consciousness and neuroimaging.
TLDR
Evidence from studies with positron emission tomography and functional magnetic resonance imaging indicating that priming, a form of implicit retrieval, is associated with decreased activity in various cortical regions is considered, as well as recent efforts to probe the relation between the phenomenological character of remembering and neural activity.

Oscillatory gamma activity in humans and its role in object representation
TLDR
This article will focus on the literature on gamma oscillatory activities in humans and will describe the different types of gamma responses and how to analyze them, as well as convergence evidence that suggests that one particular type of gamma activity (induced gamma activity) is observed during the construction of an object representation.
