“…However, MTL activity is not always observed during feedback learning (Delgado, Miller, Inati, & Phelps, 2005; Delgado, Nystrom, Fissell, Noll, & Fiez, 2000; Dobryakova & Tricomi, 2013; Shohamy et al 2004a; Tricomi, Delgado, & Fiez, 2004; Wilkinson et al, 2014)—a process that seems to be more reliant on the integrity of the BG as evidenced by difficulties in learning via feedback expressed by patients with Parkinson’s disease (Foerde, Braun, & Shohamy, 2013a; Foerde, Race, et al, 2013b; Foerde & Shohamy, 2011a, b; Jahanshahi, Wilkinson, Gahir, Dharminda, & Lagnado, 2010; Knowlton, Mangels, & Squire, 1996; Myers et al 2003; Shohamy et al 2004a, b; Wilkinson, Lagnado, Quallo, & Jahanshahi, 2008), but not with patients with amnesia (Foerde, Race, et al, 2013b; Knowlton et al 1996; Knowlton, Squire, & Gluck, 1994; Myers et al 2003). Given the conflicting results and differences across paradigms, it is unclear what aspects of feedback learning engage the MTL, particularly the hippocampus.…”
