This review will focus on the phenomenon of functional facilitation after hippocampal lesion. It consists of the following parts: After a brief overview of hippocampal anatomy and its presumed functions, brain lesions as such will shortly be addressed regarding their general role in neuroscience, as well as critical limitations, which have to be considered when trying to interpret their outcomes. Then, facilitatory effects, mainly from humans, will shortly be addressed with respect to lesions outside the hippocampus, followed by a historical account of hippocampal lesion effects. In more detail, the roles of species, lesion techniques, and behavioral tests will be outlined and discussed in light of prevalent theories of hippocampal function. Here, active avoidance will receive special attention, since tests of active avoidance learning have provided the classical facilitatory effects. Other Pavlovian and instrumental tests will then be described, showing that facilitatory effects can actually be found in rather different paradigms, which makes it difficult to relate the consequences of hippocampal lesions to a unique mechanism. Special emphasis will be given to our own work with an instrumental serial reaction time task in rats, where we studied facilitatory effects of hippocampal lesions in detail, addressing factors such as instrumental versus sequential learning, post-reinforcement pauses, extinction, and action-outcome relationships. Compared to the rich evidence obtained in experimental animals, similar knowledge in human subjects is almost entirely lacking. Nevertheless, the facilitation issue might deserve more clinical attention in the future, since some facilitated function, possibly due to enhanced impacts of undamaged and learning-relevant brain structures (such as in the basal ganglia), might also be useful to help compensate for hippocampal losses in humans.
