...The developmental trajectory of brain regional volumes in humans has been studied (Giedd et al., 1996; Sowell et al., 1999; Gogtay et al., 2006; Demaster and Ghetti, 2013) and is generally similar to that found in rats (Calabrese et al., 2013; Oguz, et al., 2013)....

...DeMaster and Ghetti (2013) scanned children aged 8–11-year old and adults aged 18–25-year old who were asked whether a drawing shown on the screen had been presented before or not (item memory) and what colour was the border of the drawing during its first presentation (context or source memory)....

...2008) and based on research with fMRI showing the most sizeable differences from adults in the functional profile in the hippocampus (DeMaster and Ghetti 2012; Ghetti et al. 2010; Paz-Alonso et al. 2008; for evidence of developmental differences in hippocampal activation profile, see also Maril et al. 2010)....

...We had proposed the prediction that the hippocampal tail may be involved in episodic retrieval in children based on our recent results showing that children recruited the hippocampal tail bilaterally, but not the rest of the hippocampus, to retrieve episodic detail (DeMaster and Ghetti 2012); thus, it is possible that this region is the first during development to capture associations with episodic memory....

...…research; performance on these tasks has been shown to relate to typically developing hippocampal structure (DeMaster et al., 2013) and function (DeMaster and Ghetti, 2012; Ghetti et al., 2010a), and has been found to be sensitive to subtle purported hippocampal damage (Ghetti et al., 2010b)....

...Models of brain development underscore the importance of neurobiological changes occurring in adolescence (e.g., Casey et al., 2010; Crone, 2009; Dahl, 2004); recent studies document associations between levels of circulating sex hormones and hippocampal volumes during adolescence (Bramen et al.,…...

...Though debate on this differentiation is still ongoing (Chua et al., 2007; Greicius et al., 2003; Moser and Moser, 1998; Schacter and Wagner, 1999), recent fMRI work by Giovanello et al. (2009) provided evidence that anterior and posterior regions may be critical for distinct retrieval processes....
