Traditionally, 'metacognition' has been thought to be the purview of primates, but it is now shown that rats may compute and use estimates of their own confidence when making difficult perceptual decisions. The paper finds correlates of task difficulty and predictors of trial-by-trial outcome in the activity of orbitofrontal cortex, which may be most parsimoniously explained as a representation of subjective confidence.
