To detect GABAergic neurons, immunocytochemical method was applied, with the use of rabbit polyclonal antibodies against GAD-67. It was found that in the first postnatal week, ventral and lateral STN subnuclei demonstrated high GABA expression as suggested by a significant number of GAD-67-immunopositive neurons; their number in the ventral subnucleus was almost 1,3 times higher than in the lateral one. During the second and third weeks, GABA expression decreased and, simultaneously, the density of terminals and synaptic structures containing GABA in neuropil of both subnuclei increased. It was shown that prenatal deficiency of serotonin in ventral and lateral STN subnuclei resulted in sharp decrease of GABA expression in the early postnatal period. By the end of the third week, a loose network of GABAergic terminals remained in the neuropil, and the density of synaptic structures increased.</p></abstract><trans-abstract xml:lang="ru"><p>Изучена динамика формирования тормозной нейральной ГАМК-ергической сети в вентральном и латеральном субъядрах ядра одиночного тракта (ЯОТ) в раннем постнатальном периоде у крыс Вистар в норме и при пренатальном дефиците серотонина (n=27). Был применен метод иммуноцитохимического выявления ГАМК-ергических нейронов с использованием кроличьих поликлональных антител к GAD-67. Обнаружено, что в исследованных субъядрах ЯОТ в 1-ю неделю постнатального развития имеет место высокая экспрессия ГАМК, о чем свидетельствует значительное количество GAD-67иммунопозитивных нейронов, при этом в вентральном субъядре их почти в 1,3 раза больше, чем в латеральном. В течение 2-йи 3-й недели происходит снижение экспрессии ГАМК и одновременно с этим в нейропиле обоих субъядер увеличивается плотность сети терминалей и расположения синаптических структур, содержащих ГАМК. Показано, что пренатальная недостаточность серотонина в вентральном и латеральном субъядрах ЯОТ вызывает резкое снижение экспрессии ГАМК в ранние постнатальные сроки развития. В нейропиле к концу 3-й недели сохраняется рыхлая сеть ГАМК-ергических терминалей и увеличивается плотность расположения синаптических структур.</p></trans-abstract><kwd-group xml:lang="en"><kwd>solitary tract nucleus</kwd><kwd>respiratory nuclei</kwd><kwd>GABA</kwd><kwd>serotonin</kwd><kwd>early postnatal period</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ядро одиночного тракта</kwd><kwd>респираторные субъядра</kwd><kwd>ГАМК</kwd><kwd>серотонин</kwd><kwd>ранний постнатальный период</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Попова Н.
