Aim. When transplanting the neurosecretory complex of the human’s diencephalon, the preservation of blood vessels that supply this area is a prerequisite. Material and Methods. Methods of brain extraction, which are used in pathoanatomical practice, do not provide this, since they lead to rupture of arteries of the hypothalamic-hypophyseal region, vessels of the epiphysis (G. V. Shor, 1925, A. I. Abrikosov, 1948, I. I. Medvedev, 1969). Methods of human brain extraction developed by V. D. Gvozdevich (patents № 548263, № 919663) are innovative methods. This method consists of several stages and involves the detachment of the dura mater from the base of the skull, the separation of the anterior inclined processes and the back of sella turcica from the sphenoid bone, the separation of tentorium cerebelli from the occipital bone. Results and Discussion. The brain extracted by this method contains a neurosecretory complex of the diencephalon and two patches of the dura mater: one - with the hypophysis and cavernous parts of the internal carotid arteries with the preserved pituitary stalk, the other - with a tentorium cerebelli with a direct venous sinus and an epiphysis. The brain drug extracted by this method preserves the natural relationship between the hypophysis, the hypothalamus, the thalamus, the epiphysis and the main sources of blood supply - the cavernous and supraclinoid segment of the internal carotid arteries, the basilar arteries, the anterior, middle and posterior medullary arteries, the anterior and posterior connective arteries. Conclusions. Such a preparation can be used as a neurosecretory transplant.
