Functional brain imaging studies have further shown that medial temporal, parietal and prefrontal cortices are involved in recognition memory of prior episodes (Rugg & Wilding, 2000; Rugg & Yonelinas, 2003). The functional role that these regions play in memory retrieval, however, is still debated. Specifically, it is unclear whether recollection, the retrieval of specific context-based information about a past experience, and familiarity, an acontextual sense that an event has been previously experienced (Tulving, 1985), are mediated by dissociated neural systems or separate strong (i.e., remote) memories from weak (i.e., recent) memories. Some studies suggest that separate cortical networks (Yonelinas et al., 2005) and differential activation in the parietal cortex (Vilberg & Rugg, 2007) mediate these two distinct memory processes, whereas other studies suggest that recollection and familiarity reflect differences in the strength of a common memory trace (Donaldson, 1996; Dunn, 2004; Gonsalves et al., 2005; Squire et al., 2007; Wixted, 2007). Yago and Ishai (2006) found that activation elicited by new paintings in the parietal cortex was reduced with decreased similarity to old items, whereas in the hippocampus and precuneus, stronger responses were evoked by new, visually different paintings.

[...] Moreover, activation elicited by new paintings in parietal cortex was reduced with decreased similarity to the old items, whereas in the hippocampus and precuneus, stronger responses were evoked by the new, visually different paintings.
