Conference in French : Neuroanatomical and neurofunctional correlates of human memory

Abstract
What we commonly name “memory” refers to episodic memory, a term originally coined by Endel Tulving in 1972. Episodic memory is the memory of autobiographical events embedded in a specific time and place, associated to phenomenological characteristics, such as emotions and contextual details (who, what, when, where, why). Hence, episodic autobiographical memory retrieval entails a complex set of operations, including self-reflection, emotion, visual imagery, attention, executive functions and semantic processes. Brain imaging represents an important contribution to the development of theoretical models of memory and recent methodological advances can tract the many cortical areas associated to autobiographical remembering, showing strong communication across distant cortical sites. Brain imaging has been used both in healthy subjects and patients affected by a memory disorder (Alzheimer’s disease, semantic dementia, post-traumatic stress disorder). Recent studies have explored the role of episodic memory in future thinking or the capacity of mentally projecting ourselves in the future, as a means to anticipate and evaluate upcoming events before they happen.
