Neurocognitive Development of Declarative Memory

Regions in the medial-temporal lobes (MTL) and prefrontal cortex are critically involved in declarative memory. These regions undergo structural and functional change during childhood and adolescence. To date, however, relatively little is known about how this neural development is related to developmental improvements in mnemonic behavior. In my presentation, I will focus on developmental changes in brain-behavior associations underlying episodic memory, operationalized as the ability to remember events in association with qualitative details. First, I will present the results of functional neuroimaging studies showing that changes in MTL recruitment may mediate age-related improvements in episodic memory encoding and retrieval. Second, I will present results of behavioral work with children suffering from Type-1 Diabetes; these data document specific episodic memory deficits in this population, which are putatively ascribed to hippocampal damage; deficits in other populations with selective brain damage will also be discussed. Finally, I will present preliminary behavioral and neuroimaging evidence of sex differences underlying the development of episodic memory. I will focus my discussion on questions about continuity and change in the network of brain regions involved in episodic memory.
