“…In healthy individuals, however, the effect of APOE on hippocampal volume remains unclear (Raz et al, 2015). Although some studies reported a negative relationship between the APOEε4 variant and hippocampal volume (Chiang et al, 2011;den Heijer et al, 2012), others did not find such an association (Troyer et al, 2012;Ferencz et al, 2013; see also Raz et al, 2015). Similarly, Troyer et al (2012) found a negative relationship between the APOEε4 variant and associative memory and a negative relationship between the APOEε4 variant and hippocampal volume in individuals with amnestic MCI.…”

Evidence from neuroimaging studies suggests a critical role of hippocampus and inferior frontal gyrus (IFG) in associative relative to item encoding. Here, we investigated similarities and differences in functional brain correlates for associative and item memory as a function of encoding instruction. Participants received either incidental (animacy judgments) or intentional encoding instructions while fMRI was employed during the encoding of associations and items. In a subsequent recognition task, memory performance of participants receiving intentional encoding instructions was higher compared with those receiving incidental encoding instructions. Furthermore, participants remembered more items than associations, regardless of encoding instruction. Greater brain activation in the left anterior hippocampus was observed for intentionally compared with incidentally encoded associations, although activity in this region was not modulated by the type of instruction for encoded items. Furthermore, greater activity in the left anterior hippocampus and left IFG was observed during intentional associative compared with item encoding. The same regions were related to subsequent memory of intentionally encoded associations and were thus task relevant. Similarly, connectivity of the anterior hippocampus to the right superior temporal lobe and IFG was uniquely linked to subsequent memory of intentionally encoded associations. Our study demonstrates the differential involvement of anterior hippocampus in intentional relative to incidental associative encoding. This finding likely reflects that the intent to remember triggers a specific binding process accomplished by this region.
