    Noradrenaline blockade specifically enhances metacognitive performance

    Tobias U Hauser et al.
    The neurotransmitter noradrenaline selectively modulates metacognition, the conscious insight into one's performance, but does not alter perceptual decision making, revealing that different neuromodulators affect different stages of a decision making process.

    Neural evidence accumulation persists after choice to inform metacognitive judgments

    Peter R Murphy et al.
    Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.

    Unexpected arousal modulates the influence of sensory noise on confidence

    Micah Allen et al.
    Changes in physiological arousal – as revealed by pupil dilation and heart rate – shape our confidence in decisions about uncertain perceptual information.

    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

    Human observers have optimal introspective access to perceptual processes even for visually masked stimuli

    Megan A K Peters, Hakwan Lau
    Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.

    Distinct neural mechanisms underlie the success, precision, and vividness of episodic memory

    Franziska R Richter et al.
    Combining fMRI with continuous model-based measures of retrieval enables the behavioral and neural dissociation of multiple components of episodic memory.

    Neural basis of somatosensory target detection independent of uncertainty, relevance, and reports

    Pia Schröder et al.
    Neural correlates of somatosensory target detection are restricted to secondary somatosensory cortex, whereas activity in insular, cingulate, and motor regions reflects stimulus uncertainty and overt reports.

    Anterior insular cortex plays a critical role in interoceptive attention

    Xingchao Wang et al.
    Anterior insular cortex activity predicts how well we attend to our bodily signals, while lesions to this brain region disrupt this ability.

    Mesolimbic confidence signals guide perceptual learning in the absence of external feedback

    Matthias Guggenmos et al.
    Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.
