This study investigates whether stimulus detection and confidence evaluation in the human cortex use shared or modality-specific circuits, finding evidence for supramodal coding in detection and partial supramodal coding in confidence.

The paper uses human single neuron recordings to show that subthalamic nucleus and thalamus neurons modulate activity during vibrotactile stimulus detection, suggesting their role in consciousness.

This paper introduces a leaky evidence accumulation model to explain perceptual confidence and subjective duration in a face detection task under temporal uncertainty.

This study identifies overlapping neural mechanisms for evidence accumulation, confidence, and changes of mind in specific brain regions using intracranial recordings and computational modeling.

The paper shows evidence accumulation in brain regions explains perceptual experience and confidence, using neural data from 29 participants.

The paper investigates how prior information influences discrimination decisions and confidence, finding that priors are underweighted in decisions but more optimally used in confidence.

The paper shows that humans can adjust confidence ratings for unaware visuomotor deviations using summary statistics, challenging the idea of limited action monitoring.

The paper investigates whether numerosity estimations for self-generated words are attenuated, finding increased functional connectivity in the intraparietal sulcus during self-generated word estimation.

The paper shows that perceptual consciousness and reflexive monitoring are governed by evidence accumulation, using neuronal recordings and a computational model.

This study investigates how confidence in perceptual decisions arises by isolating decisional and post-decisional contributions using multimodal imaging.
