Fig. 7.

Sagittal summary diagram of the afferents to the VLPO. Major regions projecting to the VLPO are indicated bydots, with one dot indicating roughly 10 retrogradely labeled neurons (counted in every fifth section, average of 3 cases). Line thickness roughly indicates intensity of varicosity density in VLPO core, which does not always correlate with density of retrograde labeling. *Because the ventral subiculum does not appear in the sagittal level shown, retrogradely labeled neurons in the ventral subiculum are depicted more dorsally than they appear in the brain.
