title: [Changes in the dendrite ultrastructure of the cerebral cortex neurons in human tumors located in the hypothalamo-hypophyseal area].
abstract: By means of electron microscopy method of bioptic material structure of the neuronal islets of the cerebral cortex has been studied in 5 persons with benign tumors that immediately effect the hypothalamus. Certain changes in ultrastructure of dendrites are revealed according to the light and dark types, as well as axons, degenerating according to the dark type. The greatest changes, including degeneration according to the dark type, undergo small branches of the dendrites. Similar pictures reflect, evidently, reduction of the dendritic tree in slightly changed cortical neurons, connected with breaking of trophic influences in the hypothalamus, evoked in it by the tumor.
