КРАТКИЕ СООБЩЕНИЯ CHANGES OF THE STRUCTURAL ORGANIZATION OF THE NUCLEUS RAPHE PALLIDUS AFTER THE DECREASE OF ENDOGENOUS SEROTONIN LEVEL IN THE PRENATAL PERIOD OF DEVELOPMENT IN RATS L. <...> Shishko The role of serotonin in the nucleus raphe pallidus (NRP) development and the dynamics of its serotonin-producing neurons were studied during various time points of the postnatal period in normal Wistar rats and in animals developing prenatally under the conditions of serotonin deficiency. <...> It was shown that NRP contained 2 populations of serotoninergic neurons with different morphological characteristics. <...> At the initial stages of postnatal development (Day 5) serotonin-producing neurons included only large neurons, while the synthetic activity of small Морфология. <...> Serotonin deficiency during prenatal development lead to the disturbance of NRP structural organization. <...> In comparison with the control animals, the size and the number of serotonin-producing neurons of both populations was decreased, their size remained unchanged with the age. <...> The damage observed may change the serotoninergic innervation of the medullary nuclei, responsible for the cardiorespiratory the control, thus causing the disturbances of cardio-vascular and respiratory systems. <...> Key words: nucleus raphe pallidus, neurons, populations, serotonin Laboratory of the Nervous System Ontogenesis, RAS I. <...> Petersburg © Е.
