[The structural characteristics of the dendritic apparatus of transplanted neurons from the embryonic amygdala].

Two main neuronal classes were studied in the grafts of basolateral nucleus of the rat embryonic amygdala stained by the Golgi method--sparsely and densely ramified cells. Transplantation resulted in the increase of dendrite length and ramification of sparsely ramified cells, in the decrease of cell body size and increase of ramification of densely ramified cells. The analysis of polar histograms of the dendritic orientation shows the selective increase of dendrite length and ramification of the both neuronal classes. The dendrites of the intact neurons of basolateral amygdala are distributed almost regularly, they do not display any dominant orientation. After transplantation the main orientation to the area of graft-host integration appears. The changes in dendrites are discussed with respect to the ability of the graft to take part in compensation of the damaged brain functions.
