Neural Basis of Autobiographical Memory
The results of functional neuroimaging studies of autobiographical memory can inform our understanding of the neural correlates of recollection in several ways. First, autobiographical memory typically involves an integration of episodic and semantic memories, and thus, the extent of recollection during autobiographical memory retrieval varies depending on the relative contribution of these two forms of memory. Second, autobiographical memory construction involves a protracted retrieval time that allows for the examination of the multiple retrieval processes mediating recollection. Third, properties that might modulate recollection processes, such as emotion, vividness, and remoteness are more easily examined at the upper boundary in autobiographical memory. This chapter focuses on these three domains where functional neuroimaging studies of autobiographical memory can make unique contributions to our understanding of the complex nature of recollection. Before turning to these domains, the main functional neuroimaging methods for investigating autobiographical memory are first reviewed, which differ primarily in their ability to elicit recollection.
