title: [Circadian rhythm of neurosecretion of the macrocellular hypothalamic nuclei under different lighting conditions].
abstract: Parameters of diurnal changes in the diameter of neuronal nuclei of the supraoptical and paraventricular nuclei in the hypothalamus of hybrid mice F1 (CBA X C57BL/6) depend on the duration of illumination and dark periods. Biwave character of variations is preserved at changing the illumination regime from 6C + 18T to 18C + 6T. Certain specificity in diurnal changes of neurosecretory activity of the nuclei under investigation is noted.
