TLDR
This work defends the higher-order view against several major criticisms, such as prefrontal activity reflects attention but not awareness, and prefrontal lesion does not abolish awareness.About:

Attentional routes to conscious perception
Ana B. Chica,Paolo Bartolomeo +1 more
TL;DR: Evidence is shown that distinct sorts of spatial attention can have different effects on visual conscious perception, and Fronto-parietal networks important for spatial attention constitute plausible neural substrates for the interactions between exogenous spatial attention and conscious perception.
Journal ArticleDOI
Using Neuroscience to Help Understand Fear and Anxiety: A Two-System Framework.
Joseph E. LeDoux,Daniel S. Pine +1 more
TL;DR: It is argued that failure to recognize and consistently emphasize a distinction between circuits underlying two classes of responses elicited by threats has impeded progress in understanding fear and anxiety disorders and hindered attempts to develop more effective pharmaceutical and psychological treatments.
Journal ArticleDOI
A signal detection theoretic approach for estimating metacognitive sensitivity from confidence ratings.
TL;DR: The measure meta-d', which reflects how much information, in signal-to-noise units, is available for metacognition, is called, and is found that subjects' metacognitive sensitivity was close to, but significantly below, optimality.

Confidence in value-based choice
Benedetto De Martino,Benedetto De Martino,Stephen M. Fleming,Stephen M. Fleming,Stephen M. Fleming,Neil Garrett,Raymond J. Dolan +6 more
TL;DR: These findings provide a mechanistic link between noise in value comparison and metacognitive awareness of choice, enabling us both to want and to express knowledge of what the authors want.

Conscious Processing and the Global Neuronal Workspace Hypothesis.
George A. Mashour,Pieter R. Roelfsema,Pieter R. Roelfsema,Jean-Pierre Changeux,Jean-Pierre Changeux,Jean-Pierre Changeux,Stanislas Dehaene,Stanislas Dehaene +7 more
TL;DR: The GNW hypothesis proposes that, in the conscious state, a non-linear network ignition associated with recurrent processing amplifies and sustains a neural representation, allowing the corresponding information to be globally accessed by local processors.

Journal ArticleDOI
The disunity of consciousness.
TL;DR: It is proposed that the quest for the NCC will remain elusive until it is acknowledged that consciousness is not a unity, and that there are instead many consciousnesses that are distributed in time and space.
Journal ArticleDOI
Unconscious Activation of the Prefrontal No-Go Network
TL;DR: It is demonstrated that an unconscious no-go stimulus also can activate prefrontal control networks, most prominently the IFC and the pre-SMA, and neural differences between conscious and unconscious control are revealed.
Journal ArticleDOI
What Is Consciousness
TL;DR: The paper takes a concrete example from Searle's review, reanalyses it within Freud's metapsychological frame of reference, and shows how this frame provides a radical solution to the problem.
Journal ArticleDOI
Integration Without Awareness: Expanding the Limits of Unconscious Processing
TL;DR: It is demonstrated that integration of objects with their background scenes can be achieved without awareness of either object or background scenes, and visual awareness is not needed for object-background integration or for processing the likelihood of an object to appear within a given semantic context.

The Nature of the Mind
TL;DR: Men have minds, that is to say, they perceive, they have sensations, emotions, beliefs, thoughts, purposes, and desires as discussed by the authors. But what is it to have a mind?
