Popis:	A study was made of the possibility of obtaining uncoditioned reflex shifts in the cardiac activity of the chick embryo in response to exteroceptive stimuli in acute and chronic experimental conditions; a possibility of elaborating a reflex to the cardiac activity during the embryonic period was studied as well. Experimental results indicated that control of the cardiac activity was in the phase of formation up to the 17th day of the chick embryo development. Unconditioned reflex control of the cardiac activity was manifested begining from the 17th day of the embryonic development. At the same period it is possible to elaborate a temporary reflex to the cardiac activity, which points to a considerable widening of the regulation possibilities by the end of embryogenesis in representatives of birds which hatched mature.
