UNASSIGNED: Effective visual memory encoding, a function important for everyday functioning, relies on episodic and semantic memory processes. In @entity1 with @entity1315 ( @entity1315 ), @entity2414 are common as the structures typically involved in @entity410 generation are also involved in acquisition, maintenance, and retrieval of episodic memories. In this study, we used group independent component analysis (GICA) combined with Granger causality analysis to investigate the neuronal networks involved in visual memory encoding during a complex fMRI scene-encoding task in @entity1 with left @entity1315 (LMTLE; N=28) and in @entity1 with @entity4265 ( @entity4265 ; N=18). Additionally, we built models of memory encoding in LMTLE and @entity4265 and compared them with a model of healthy memory encoding (Nenert et al., 2014). For those with LMTLE, we identified and retained for further analyses and model generation 7 ICA task-related components that were attributed to four different networks: the frontal and posterior components of the DMN, @entity227 , and an "other" network. For those with @entity4265 , @entity6455 produced 9 task-related components that were attributed to the somatosensory and cerebellar networks in addition to the same networks as in @entity1 with LMTLE. Granger causality analysis revealed group differences in causality relations within the visual memory network and @entity1315 -related deviations from normal network function. Our results demonstrate differences in the networks for visual memory encoding between those with LMTLE and those with @entity4265 . Consistent with previous studies, the organization of memory encoding is dependent on laterality of @entity410 focus and may be mediated by functional reorganization in chronic @entity302 . These differences may underlie the observed differences in memory abilities between @entity1 with LMTLE and @entity1 with @entity4265 and highlight the modulating effects of @entity302 on the network for memory encoding.
