“…Notably, during CPP testing, entrance to the drug‐paired context is preceded by phase‐locked hippocampal theta rhythm (Takano, Tanaka, Takano, & Hironaka, ), suggesting the involvement of the hippocampus in reward memory retrieval of contextual cues. On a causative level, pharmacological disruptions or lesions of the hippocampus and dentate gyrus interfere with many stages of CPP, including the acquisition and retrieval of the drug/context association (Ebrahimian et al, ; Ferbinteanu & McDonald, ; Guo et al, ; Hernández‐Rabaza et al, ; Hitchcock & Lattal, ; Katebi, Farahimanesh, Fatahi, Zarrabian, & Haghparast, ; Meyers, Zavala, & Neisewander, ; Meyers, Zavala, Speer, & Neisewander, ; Milekic, Brown, Castellini, & Alberini, ; Rezayof, Zatali, Haeri‐Rohani, & Zarrindast, ; Sadeghi, Ezzatpanah, & Haghparast, ; Taubenfeld, Muravieva, Garcia‐Osta, & Alberini, ; Zarrindast, Nouri, & Ahmadi, ), and interfere with other animal models of addiction‐relevant behaviors (Fuchs et al, ; Ramirez et al, ; Paniccia et al, ). Such studies in laboratory animals support that the hippocampus and dentate gyrus play an important role in context‐dependent reward memory (Smith & Bulkin, ).…”
