TLDR
It is shown that the same neurons that represent formation of a decision encode certainty about the decision, which in humans would be described as the degree of confidence in one's decision.Abstract:
The degree of confidence in a decision provides a graded and probabilistic assessment of expected outcome. Although neural mechanisms of perceptual decisions have been studied extensively in primates, little is known about the mechanisms underlying choice certainty. We have shown that the same neurons that represent formation of a decision encode certainty about the decision. Rhesus monkeys made decisions about the direction of moving random dots, spanning a range of difficulties. They were rewarded for correct decisions. On some trials, after viewing the stimulus, the monkeys could opt out of the direction decision for a small but certain reward. Monkeys exercised this option in a manner that revealed their degree of certainty. Neurons in parietal cortex represented formation of the direction decision and the degree of certainty underlying the decision to opt out.read more

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.

Diffusion Decision Model: Current Issues and History
TL;DR: This review relates the diffusion models to both earlier and more recent research in psychology to examine individual differences in cognitive and neural processes of speeded decision making.

Attention, Intention, and Priority in the Parietal Lobe
TL;DR: It is proposed that LIP acts as a priority map in which objects are represented by activity proportional to their behavioral priority and the spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention.

TL;DR: The ability to introspect about self-performance is key to human subjective experience, but the neuroanatomical basis of this ability is unknown as discussed by the authors, and it is unknown whether this interindividual variability was associated with a distinct neural basis.
