the mosaic of origin and termination of the various connections indicates that the convexity of the frontal lobe ( especially its caudal half ) is reciprocally associated with the parietal and temporal cortex , while the major associations with the hippocampal mechanism originate from two separate areas , viz . the caudal orbitofrontal cortex and a region dorsal to the sulcus principalis , frontal fields from which also the major fronto-hypothalamic connections arise .
