A Novel type of confidence revealed by neural activities of the primate pulvinar

The primate pulvinar, a visual thalamic region, has showed remarkable expansion through evolution. However, its functional role has been enigmatic. Here, using a combination of neural recordings, pharmacological inactivation and computational modeling, we found that responses of pulvinar neurons encode a subjectís certainty of visual categorization and contribute to perceptual confidence. The current findings can open a new window for unraveling the neural mechanisms of normal and disordered sensory awareness.
