The medial temporal lobe revisited
Dr Tim Bussey
Dept of experimental Psychology, Cambridge, UK
The dominant view of the anatomical organisation of memory is that declarative memory is mediated by a medial temporal lobe memory system consisting of several distinct structures, including the hippocampus and perirhinal cortex. The strong version of this view assumes equipotentiality of function within this region and serial organisation, such that double dissociations between individual structures should not be possible. It is thought, furthermore, that structures in this region have a selective role in memory, but do not participate in other functions such as perception. I will present data that challenge these aspects of the dominant view, and will suggest an alternative model.
