Its inactivation caused selective impairment of metamemory, but not of memory itself.<\/p>\n<p>The results pave the way to further study of the neuronal underpinnings of metacognition using an animal model, where metamemory has previously been difficult to evaluate.<\/p>\n<figure class=\"spip-document spip-document-17663 aligncenter\"><img decoding=\"async\" src=\"https:\/\/en-images.igihe.com\/jpg\/170112141210_1_540x360.jpg\" alt=\"Retrospection: Self-reflection of one&#039;s own past.\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>{Researchers have pinpointed a brain region monkeys use to evaluate their ability to recall memories.
