The importance of the medial temporal lobe to episodic memory has been recognized for decades. Recent human fMRI findings have begun to delineate the functional roles of different MTL regions, most notably the hippocampus, in the retrieval of episodic memories. Importantly, these studies have also identified a network of cortical regions – each interconnected with the MTL – that are also consistently engaged during successful episodic retrieval. Along with the MTL these regions appear to constitute a content-independent network that acts in concert with cortical regions representing the contents of retrieval to support consciously accessible representations of prior experiences.

• Neural reactivation in parietal cortex enhances memory for episodically linked information (2018, neutral): “Furthermore, retrieval practice might result in reactivation in lateral and medial parietal regions, which is known as the “Posterior Medial” (PM) or “Default Mode” network (15, 16).”
• Contributions of episodic retrieval and mentalizing to autobiographical thought: evidence from functional neuroimaging, resting-state connectivity, and fMRI meta-analyses (2014, neutral): “continued debate surrounds the precise functional role of these regions in memory retrieval (Cabeza et al., 2008; Ranganath and Ritchey, 2012; Rugg and Vilberg, 2013; Vann et al., 2009; Vilberg and Rugg, 2008; Wagner et al., 2005).”
• The hippocampus and related neocortical structures in memory transformation. (2018, neutral): “The focus of our review has been on the hippocampus and mPFC, yet it is well known that episodic/context-speci fi c memory depends on the interaction of a variety of regions [59,60,104,178,179], only a handful of which were mentioned in this paper.”
• Episodic Memory and Beyond: The Hippocampus and Neocortex in Transformation (2016, neutral): “…network, these regions overlap substantially with those activated during recall of vivid, autobiographical memories (Cabeza & St. Jacques 2007, Rugg & Vilberg 2013, Svoboda et al. 2006) and include HPC, PHC, medial prefrontal cortex (mPFC), VPC (angular gyrus), and retrosplenial…”
• Discovering event structure in continuous narrative perception and memory (2016, neutral): “…Esteva, Beck, & Fei-Fei, 2016), are part of the “general recollection network” with strong anatomical and functional connectivity to the hippocampus (Rugg & Vilberg, 2013), and are the core components of the posterior medial memory system (Ranganath & Ritchey, 2012), which is thought to represent…”
• Precision functional mapping of individual human brains (2017, neutral): “…have been able to reliably identify central tendencies of both task-induced activation patterns (Martin, 2007; Petersen and Posner, 2012; Rugg and Vilberg, 2013; Wager and Smith, 2003) and the large-scale network organization of the brain (Beckmann et al., 2005; Power et al., 2011;…”
