TLDR
It is shown that introspective ability is correlated with gray matter volume in the anterior prefrontal cortex, a region that shows marked evolutionary development in humans, and this findings point to a focal neuroanatomical substrate for introspection ability, a substrate distinct from that supporting primary perception.About:

Experimental and Theoretical Approaches to Conscious Processing
TL;DR: Converging neuroimaging and neurophysiological data point to objective neural measures of conscious access: late amplification of relevant sensory activity, long-distance cortico-cortical synchronization at beta and gamma frequencies, and "ignition" of a large-scale prefronto-parietal network.

The structural basis of inter-individual differences in human behaviour and cognition
TL;DR: It is proposed that inter-individual differences can be used as a source of information to link human behaviour and cognition to brain anatomy.

Knowing your own heart: distinguishing interoceptive accuracy from interoceptive awareness.
Sarah N. Garfinkel,Sarah N. Garfinkel,Anil K. Seth,Adam B. Barrett,Keisuke Suzuki,Hugo D. Critchley +5 more
TL;DR: Empirical support for dissociation between dimensions of interoceptive accuracy, sensibility and awareness is provided and set the context for defining how the relative balance of accuracy, Sensibility and Awareness dimensions explain cognitive, emotional and clinical associations of interOceptive ability.

How to measure metacognition
TL;DR: Other measures based on signal detection theory and receiver operating characteristics (ROC) analysis that are “bias free,” are reviewed, and these quantities are related to the calibration and discrimination measures developed in the probability estimation literature.

The entropic brain: a theory of conscious states informed by neuroimaging research with psychedelic drugs

TL;DR: It is argued that the defining feature of “primary states” is elevated entropy in certain aspects of brain function, such as the repertoire of functional connectivity motifs that form and fragment across time, and that this entropy suppression furnishes normal waking consciousness with a constrained quality and associated metacognitive functions, including reality-testing and self-awareness.

Corpus callosal connection mapping using cortical gray matter parcellation and DT-MRI
TL;DR: The probabilistic subdivision of the corpus callosum by connecting cortical gray matter provides a more precise understanding of the CC.

The effects of viewing angle, camera angle, and sign of surface curvature on the perception of three-dimensional shape from texture.
TL;DR: The results reveal that the apparent patterns of relief from texture are systematically underestimated; convex surfaces appear to have greater depth than concave surfaces, large camera angles produce greater amounts of perceived depth than small camera angles, and the apparent depth-to-width ratio for a given image of a surface is greater for small viewing angles than for large viewing angles.

Dissociation Between Memory Accuracy and Memory Confidence Following Bilateral Parietal Lesions
Jon S. Simons,Polly V. Peers,Yonatan S. Mazuz,Marian E. Berryhill,Marian E. Berryhill,Ingrid R. Olson +5 more
TL;DR: In 3 experiments, patients with bilateral parietal lesions performed as well as controls at source recollection, confirming the previous unilateral lesion results and arguing against an explanation for those results in terms of contralesional compensation.
Persistent angular structure: new insights from diffusion MRI data
TL;DR: A statistic called the radially Persistent Angular Structure (PAS) is determined from samples of the Fourier transform of a three-dimensional function, which has applications in diffusion magnetic resonance imaging (MRI) and biomedical applications, where it reveals the orientations of microstructural fibres, such as white-matter fibres in the brain.

A higher order Bayesian decision theory of consciousness.
TL;DR: This work presents a model that is free from the strong assumption that consciousness predicts superior performance, based on Bayesian decision theory, and outlines three possibilities of how conscious perception might be affected by failures of 'higher-order' representation.
