Figure 1.8.1. Corticopetal basal forebrain projection system in primates. Schematic diagram of projections from basal forebrain to cortex. The arrowheads are at corresponding points on each figure. In the cortex the allocortex of the hippocampus is shown by filled circles and the olfactory area by hatching. The same symbols are used in the diagram of the basal nucleus: hippocampus (H); medial septal nucleus (MS); nucleus of the horizontal limb of the diagonal band (NDB); olfactory cortex (OLF). (From Pearson et al., 1983).
