title: Blood supply of the rat hypothalamus. VII. The lateral hypothalamus (medial forebrain bundle).
abstract: Using the double ink-filling technique the arteries and veins of the lateral hypothalamus are described in detail. This region occupied mainly by the fibres and interposed cells of the medial forebrain bundle is supplied by some own arteries and branches of the large basal vessels. Most of the arteries running to the rostral part of the lateral hypothalamus originate from the internal carotid, others belong to the anterior and middle cerebral arteries. Blood supply of the middle part comes from the middle hypothalamic and three tuberal arteries. All arteries of the caudal part originate from the posterior communicans. The abundant drainage of the lateral hypothalamus is collected by the basal and anterior interpeduncular veins from the rostral two-thirds and the caudal one-third, respectively.
