Laminar distribution of SMI-32-positive neurons and neuronal body profile area were analyzed in intact animals (n=4) and in kittens (n=4) grown under conditions of rhythmic light stimulation with15 Hz frequency for 4 months. In light-stimulated animals, changes in laminar distribution of immunopositive neurons were detected in both LGN (decline in the percentage of the immunopositive cells in C M layer) and in PMLS area (decrease in cell count in layer V). Morphometric analysis has shown the significant reduction of cell body profile area in immunopositive neurons in light-stimulated kittens only in layers III and V of PMLS area. The data obtained suggest that Y channel functional disturbances in light-stimulated animals are caused by the structural and metabolic changes detected in Y neurons.</p></abstract><trans-abstract xml:lang="ru"><p>С целью изучения влияния искусственной бинокулярной ритмической световой стимуляции на развитие структурнофункциональной организации Y-нейронов зрительной системы кошки в онтогенезе исследовали распределение в наружном коленчатом теле (НКТ) и заднемедиальном поле латеральной супрасильвиевой борозды (PMLS) нейронов, иммунопозитивных к антителам SMI-32. Анализировали послойное распределение SMI-32-позитивных нейронов и площадь сечения их тел у интактных животных (n=4) и у котят (n=4), росших в условиях ритмической световой стимуляции с частотой 15 Гц в течение 4 мес. У стимулированных животных выявлено изменение в послойном распределении иммунопозитивных нейронов как в НКТ (снижение доли иммунопозитивных клеток в слое С М), так и в PMLS (снижение доли иммунопозитивных клеток в слое V). Морфометрический анализ показал, что у стимулированных котят происходит значимое снижение площади сечения тел иммунопозитивных нейронов только в слоях III и V области PMLS. Полученные данные позволяют предположить наличие у стимулированных животных функциональных нарушений Y-проводящего канала, обусловленных выявленными структурнометаболическими изменениями Y-нейронов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Y neurons</kwd><kwd>visual system</kwd><kwd>rhythmic light stimulation</kwd><kwd>SMI-32 antibodies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>зрительная система</kwd><kwd>Y-нейроны</kwd><kwd>ритмическая световая стимуляция</kwd><kwd>антитела SMI-32</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Меркульева Н.
