What does the hippocampus do during working-memory tasks? A cognitive-neuropsychological perspective

In this commentary, we highlight the role of the hippocampus as a binding device that may explain its recruitment during associative working-memory paradigms. Furthermore, we argue that both functional neuroimaging research, as presented in Slotnick (this issue), and carefully designed lesion studies in patients with selective bilateral hippocampal damage are crucial for advancing our understanding of the neural structures and processing involved in human memory in general and disentangling the role of the hippocampus proper and other medial temporal lobe structures in working-memory function and long-term encoding specifically.
