Visual activity in areas V3a and V3 during reversible inactivation of area V1 in the macaque monkey.

abstract：:Recent findings indicate that monkeys can report their confidence in perceptual decisions and that this information is encoded in neurons involved in making decisions, including the lateral intraparietal area (LIP) and the supplementary eye field (SEF). A key issue to consider when studying confidence is that decision...
