Analysis of confidence and accuracy. Activation maps for HC-Correct vs. LC-Correct (yellow) and HC-Incorrect vs. LC-Incorrect (red) are displayed on coronal slices: prefrontal regions shown on left at y = 27, and hippocampal regions shown on the right at y = −12). No significant overlap was found using a conjunction analysis at the threshold of P < 0.001, but at the lower threshold atP < 0.01 (shown in figure), the only region showing overlap between confidence and accuracy was found in the left inferior prefrontal cortex. There was bilateral activation in the anterior hippocampal formation for the HC-correct vs. LC-correct contrast, but no activation within the hippocampal formation for the HC-Incorrect vs. LC-Incorrect even at the lower threshold of P < 0.01.
