[The descending cortical pathways of the frontal lobe to the nuclei of the hypothalamic mamillary bodies in human craniocerebral trauma].
Structural organization of conducting ways of the frontal lobe cortex to hypothalamic nuclei was studied in sections of brain from 5 patients who died in short terms after craniocerebral trauma and during the experiment in 5 macaque rhesus monkeys with unilateral destruction of different cortical fields of frontal area. Series of brain sections were processed using silver nitrate impregnation after Bielschowsky [correction of Bilshovsky] with counterstaining of nuclear structures after Kavamura with cresyl violet. The presence of direct corticohypothalamic ways from the cortex of the orbital surface of inferior (field 47 and its subfields) and superior (field 11) frontal gyri and frontal pole (field 10) to nuclei of mamillary complex and lateral hypothalamus was established. Direct frontomamillary ways from these cortical areas terminate basically in medial mamillary nucleus. In monkey direct frontomamillary ways were distinguished in the cortex of field 47. In man widening of the area where corticohypothalamic ways arise is connected with progressive development of the telencephalic cortex and phylogenetically new formation of hypothalamus--mamillary bodies.
