Empirical support for higher-order theories of conscious awareness
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.

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.

Dopamine, the prefrontal cortex and schizophrenia:
TL;DR: Parts of the anatomy, physiology and pharmacology of the mesencephalic-frontal cortical dopamine system as they may relate to schizophrenia are described, and evidence for altered dopaminergic neurotransmission in the frontal cortex of schizophrenic patients is presented.
Journal ArticleDOI
How rich is consciousness? The partial awareness hypothesis.
TL;DR: It is argued that the empirical evidence for phenomenal consciousness without access is equivocal, resulting either from a confusion between phenomenal and unconscious contents, or from an impression of phenomenally rich experiences arising from illusory contents.
Journal ArticleDOI
Unconscious Activation of the Cognitive Control System in the Human Prefrontal Cortex
Hakwan Lau,Richard E. Passingham +1 more
TL;DR: The results suggest that the cognitive control system in the prefrontal cortex is not exclusively driven by conscious information, as has been believed previously.
Journal ArticleDOI
Causal role of prefrontal cortex in the threshold for access to consciousness.
TL;DR: It is concluded that PFC makes a causal contribution to conscious visual perception of masked stimuli, and a dual-route signal detection theory of objective and subjective decision making is outlined.

TL;DR: The unseen and the unknown, Deficits, degradation, and dissociations, and the question of "how?" are explored.
