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.

The Nature of Mind
TL;DR: Men have minds, that is to say, they perceive, they have sensations, emotions, beliefs, thoughts, purposes, and desires as mentioned in this paper. But what is it to have a mind?
Journal ArticleDOI
Hallucinations in Parkinson disease.
TL;DR: E epidemiological, phenomenological, pathophysiological and therapeutic aspects of hallucinations in PD are presented and better phenomenological discrimination, combined with neuroimaging tools, should refine therapeutic options and improve prognosis.
Journal ArticleDOI
The relationship between cortical activation and perception investigated with invisible stimuli
TL;DR: It is concluded that there is no terminal “perceptual” area in the visual brain, but that the brain regions involved in processing a visual stimulus are also involved in its perception, the difference between the two being dictated by a higher level of activity in the specific brain region when the stimulus is perceived.

Subliminal Instrumental Conditioning Demonstrated in the Human Brain
Mathias Pessiglione,Mathias Pessiglione,Predrag Petrovic,Jean Daunizeau,Stefano Palminteri,Raymond J. Dolan,Chris D. Frith +6 more
TL;DR: It is concluded that, even without conscious processing of contextual cues, the brain can learn their reward value and use them to provide a bias on decision making.
