“…For instance, rats with HPC inactivation or lesions rely less on the place strategy and more on alternative strategies during a conflict probe trial (McDonald & White, ; Packard & McGaugh, ). Hippocampus‐lesioned animals also show impaired acquisition of a place‐only‐relevant version of a plus‐maze task (Chang & Gold, ; Compton, ), a place‐relevant component of a dual‐solution water maze task (Pearce, Roberts, & Good, ; Kosaki, Poulter, Austen, & McGregor, ), and a passive place learning in the water maze, which precludes the involvement of a response component (Kosaki, Lin, Horne, Pearce, & Gilroy, ). On the other hand, Corbit and Balleine (), and Corbit, Ostlund, and Balleine (), demonstrated that HPC lesions did not impair rats' sensitivity to the expected value of the outcome.…”
