There have been a number of advances in the search for the neural correlates of consciousness — the minimum neural mechanisms sufficient for any one specific conscious percept. In this Review, we describe recent findings showing that the anatomical neural correlates of consciousness are primarily localized to a posterior cortical hot zone that includes sensory areas, rather than to a fronto-parietal network involved in task monitoring and reporting. We also discuss some candidate… 
Are the Neural Correlates of Consciousness in the Front or in the Back of the Cerebral Cortex? Clinical and Neuroimaging Evidence
TLDR
This Perspective will critically review the clinical and neuroimaging evidence for the involvement of the front versus the back of the cortex in specifying conscious contents and discuss promising research avenues.
The Neural Correlates of Access Consciousness and Phenomenal Consciousness Seem to Coincide and Would Correspond to a Memory Center, an Activation Center and Eight Parallel Convergence Centers

TLDR
A review of the literature of the pathology called “neglect” confirms that the common correlates include 10: a memory center, an activation center, and eight parallel centers, and it can be deduced that these eight parallel center would operate as points of convergence in the third person linking the respective eight sensory-motor-emotional areas activated by external perceptions and the corresponding memories of these perceptions deposited in the memory center.
Neuropsychology of Consciousness: Some History and a Few New Trends
TLDR
A review of historical steps in the formulation of consciousness as a global brain function with arousal and content as principal ingredients, respectively, instantiated in the subcortex and the neocortex reports a few fresh developments in neuropsychology and cognitive neuroscience which emphasize the importance of the hippocampus for thinking and dreaming.
Consciousness: New Concepts and Neural Networks
TLDR
This review presents the latest progress in consciousness research and proposes the assumptions with regard to the network of consciousness.
Future directions for identifying the neural correlates of consciousness.
TLDR
Questions remain to be tackled about the role of posterior (and anterior) sensory areas in conscious phenomenology and which characteristics of this activity are related to consciousness, how this activity relates to the anatomy of these areas5,6, what the under lying mechanisms are and how this is connected to information complexity.
Neural Correlates of Conscious Motion Perception
TLDR
The role of P3b is extended as a content independent NCC to conscious visual motion perception, isolating local motion, a dorsally processed feature, as the primary feature being consciously perceived.
Physically Sufficient Neural Mechanisms of Consciousness
TLDR
The conception of NCC has important implications for research methodology, neuroethics, and the vitality of the search for NCC as well as a theoretical approach to consciousness studies.

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.

TLDR
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.
Distilling the neural correlates of consciousness
The neural correlates of conscious vision.
TLDR
The broad temporal and spatial distribution of activity argues against a unified, distributed fronto-parietal correlate of consciousness and suggests that correlates of consciousness are divided into primary and secondary network nodes, with early activity in the occipital lobe correlating with perception and later activity in downstream areas with secondary processes contingent on the outcome of earlier perceptual processing.

It is sought to show how Jon Driver's insights led to a deeper understanding of the causal connections between distant brain structures that are now believed to characterize the neural underpinnings of human consciousness.
