This study has two related objectives. One is to improve our understanding of the sub- division of the parahippocampal cortex, the other is to investigate the terminal distri- bution of sulphide silver stainable fibre systems (explained below) in this region. The parahippocampal areas (comprising area entorhinalis, parasubiculum, area ret- rosplenialis e and presubiculum) transmit information to and from the hippocampus, a part of the brain which has been the subject of extensive neurobiological research. Much current anatomical work is therefore devoted to the study of the connections of the...
