Memory, amnesia, and the issue of recovered memory: Neurobiological aspects

The main thesis of this article is that the debate about the credibility of “recovered memories”—reports by adults of recovered memories of childhood sexual abuse and trauma that were allegedly repressed for many years—can be usefully informed by considering the biological and behavioral facts and ideas about how memory works. Accordingly, the first section of this review describes current facts and ideas about the neurobiology and neuropsychology of memory and amnesia, including what parts of the brain are important for memory, distinctions between different memory systems in the brain, and the phenomena of infantile amnesia and source amnesia. The second section takes into account the information about the biological and behavioral bases of memory and addresses two questions about memory that have become a focus of debate in the recovered memory controversy, that is, whether memories for traumatic events change over time, and whether memories can be created for traumatic events that did not actually happen.
