Autobiographical and episodic memory--one and the same? Evidence from prefrontal activation in neuroimaging studies.

摘要: Laboratory investigations of episodic memory often require participants to encode and later retrieve lists items (words, pictures, or faces). The underlying assumption is that recollection from the list analogous events one's past, i.e. autobiographical re-experiencing. Functional neuroimaging studies have provided extensive evidence suggesting regions prefrontal cortex (PFC) play a role in retrieval. A review PFC activations reported imaging matched sub-sets list-learning reveals patterns similarity but also substantial differences. Episodic report right mid-dorsolateral PFC, such are absent studies. Additionally, ventromedial primarily on left, almost invariably found studies, rarely occur memory. It suggested these two mediate different modes post-retrieval monitoring verification. Autobiographical relies quick intuitive 'feeling rightness' monitor veracity cohesiveness retrieved memories relation an activated self-schema. for requires more conscious elaborate avoid omissions, commissions repetitions. present analysis suggests care caution should be exercised extrapolating way we recollect 'events' learned laboratory our lives.
