The human brain is constantly generating and updating predictions. The midcingulate cortex (MCC) is one of the areas that contribute to prediction processing, while MCC layer-specific function remains unknown. In the present study, we used a tactile index finger prediction task that consists of sequential finger poking during high-resolution (0.76mm) BOLD and VASO fMRI at 7T to investigate how the prediction activity changes across layers in the human MCC. We found the double-peak activity feature across MCC layers for all prediction tasks, and the enhanced activity within MCC superficial layers may reflect the prediction error processing.
