[Study of the medial mamillary nucleus of the human hypothalamus in fresh cadavers]

Morpho-functional state of the medial mamillary nucleus of the posterior hypothalamus in patients who had died from various diseases at the age of 18 to 80 years were studied by methods of quantitative histochemistry on the material of early necropsies. Nuclear changes were revealed depending on the age, type of main disease, character of thanatogenesis. The common and the earliest changes were those of microcirculatory bed resulting in the disturbance of interrelationships in the system neuron--neuropil--vessel.
