Abstract
Spontaneous and K(+)-stimulated release of noradrenaline from the hypothalamus, adrenal gland, and organ of Zuckerkandl under their flowing incubation was investigated in the perinatal period of ontogenesis of rats. The results suggest that, during the investigated period of ontogenesis, adrenal glands are the main source of noradrenaline in the blood, whereas the contributions of the organ of Zuckerkandl and the brain are not as significant and change during this period.
