Brief description Functional magnetic resonance imaging (fMRI) is a technique which utilises differences between oxygenated and deoxygenated blood to identify regions which are active when the brain is performing a task. This enables us to determine the regions of the brain which are involved in performing different functions. The brain regions supporting memory and learning functions include the hippocampus, the posterior cingulate cortex (PCC), and the frontal lobes. Research has already established the importance of the hippocampus in memory and learning. However, the exact role of the PCC and the interaction between the PCC and other memory regions remains unclear. This study will use fMRI to investigate the role of the PCC in memory and learning. Specifically, we will compare the activity associated with performance of a difficult memory task and an easier memory task in healthy subjects. The study will then be repeated in patients sustaining damage to the hippocampus. This part of the study will allow us to see how the PCC adapts to disease in the memory system. The results of this study will further clarify the role of the PCC in memory and learning. In addition, this work may be of great importance in the treatment and rehabilitation of patients with memory disorders.
