The paper identifies multiple stable brain activation patterns for the same perceptual decision-making task using functional MRI and clustering analysis.

The paper shows that a frontoparietal brain network is domain-general for task learning, becoming more connected as learning progresses.

The paper decodes reaction time and confidence across the cortex at the individual level, finding broader brain-behavior relationships than previously observed.

The paper quantifies the contribution of subject and group factors in brain activation using a new method applied to a perceptual decision-making task.

The paper investigates neural circuits involved in perceptual decision making and confidence generation using fMRI, finding overlapping and some unique brain regions activated during these processes.

This study investigates suboptimal perceptual decision making in tasks with multiple alternatives and finds that most sensory information is lost during the transformation to decision-level representations.
