TL;DR: It is suggested that various long-axis specializations arise out of differences between the anterior and posterior hippocampus in large-scale network connectivity, the organization of entorhinal grid cells, and subfield compositions that bias the aHPC and pHPC towards pattern completion and separation, respectively.

TL;DR: It is shown that the hippocampus, when separated into posterior and anterior segments, can reliably predict recollection in healthy young adults, and it is suggested that enhanced posterior-hippocampal postencoding processes may account for the memory benefit associated with larger posterior hippocampi.

TL;DR: It is argued that proposals that state that information is encoded better if it is novel are based on over-generalizations of effects arising from the distinctiveness of novel materials, regardless of whether familiarity is experimentally induced or based on prior semantic knowledge.

TL;DR: Investigating the impact of two negative, highly arousing, and withdrawal-related emotions-disgust and fear--on attention and subsequent memory suggests that disgust appears to have a special salience in memory relative to certain other emotions, suggesting that a purely dimensional model of emotional influences on cognition is inadequate to account for their effects.

TL;DR: Because episodic memory for repeated scenes was superior, the results also support traditional views of encoding emphasizing the role of prior representations, and illuminate one way in which humans use existing memories to help form new ones.
