The role of the cholinergic nervous system in behaviour had been hypothesised since 1963,1 but it was not until the 1980s that the biochemical link between cholinergic function and memory was specified in dementia, and the nucleus basalis of Meynert was identified as the key anatomical region.2 Throughout, the hippocampus has had an important role in our understanding of memory and is an attractive target for research because it is easily identified, is anatomically well organised, and the intra- and inter-regional connections are well defined.
With the advent of modern neuroimaging techniques, these inter-regional differences in anatomical clarity became more important. The basal …
