础产蝉迟谤补肠迟:听There have been decades of research illuminating the various ways in which memory is impacted in individuals with temporal lobe epilepsy (TLE), much of it focusing on medial temporal lobe damage and dysfunction. However, encoding and retrieving information in the clinic and in everyday situations clearly depends on a network of brain regions and their interactions, including but not exclusive to hippocampal processes and representations. Our lab has been using functional MRI, and particularly measures of functional connectivity, to examine the relationship between brain connectivity and memory integrity in individuals with TLE. I will discuss three lines of our research on this topic: (1) how connectivity is altered when retrieving memories from one鈥檚 personal past; (2) how intrinsic connectivity between hippocampus and neocortex relates to memory consolidation; (3) how divergence from normative connectivity relates to current memory performance and can be used to predict memory outcomes following temporal lobe resection. The evidence suggests that network dysfunction is the appropriate level to investigate the variety of memory deficits that emerge in patients with temporal lobe epilepsy.听
