On the model of interictal discharges synchronization, a study of reciprocal inhibitory connections was carried out. In rats in light narcotic sleep, after application of GABA A-receptor blockers to the cortex, interictal discharges occurred in neighboring cortical areas independently of each other, and then synchronization occurred. In the experiments in which the interictal discharges occurred simultaneously, the durations of the slow wave (inhibitory phase) were the same. During the registration in these and other experiments, there was an increase in the time delay between the moments of interictal discharges generation. Under conditions of increased synchronization, the duration of the slow wave (inhibitory phase) of interictal discharges increased. Interictal discharges, which occurred first, had a longer duration of inhibition compared to the duration in the neighboring point, because the inhibition from the neighboring networks via feedback inhibitory connections is added to its own inhibition in the neuronal network. When excitation occurred, it was followed by inhibition via feedback, which limited the period of excitation, and thus created a temporary integration window, and this also happened in the neighboring neural networks of the cortex.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324618208">Современные экспериментальные данные показывают, что интериктальные разряды состоят из короткого спайка и медленной волны, которая рассматривается как длительная гиперполяризация. На модели синхронизации интериктальных разрядов было проведено исследование обратных тормозных связей. У крыс, находящихся в состоянии легкого наркотического сна, после нанесения блокаторов ГАМК-А-рецепторов на кору интериктальные разряды возникали в соседних участках коры независимо друг от друга, а затем происходила их синхронизация. В экспериментах, в которых интериктальные разряды возникали одновременно, длительности медленной волны (тормозной фазы) были одинаковы. В процессе регистрации в этих и других опытах происходило увеличение временно́й задержки между моментами генерации интериктальных разрядов. В условиях усиления синхронизации происходило увеличение длительности медленной волны (тормозной фазы) интериктальных разрядов. У интериктальных разрядов, которые возникали первыми, наблюдалась больша́я длительность торможения по сравнению с длительностью в соседней точке, так как к собственному торможению в нейронной сети добавляется торможение от соседних сетей по обратным тормозным связям. При возникновении возбуждения вслед за ним по обратной связи начиналось торможение, которое ограничивало период возбуждения, и таким образом создавалось временно́е окно интеграции, и это также происходило в соседних нейронных сетях коры.</p></trans-abstract><kwd-group xml:lang="en"><kwd>synchronization</kwd><kwd>interictal discharges</kwd><kwd>GABA B-receptors</kwd><kwd>reverse inhibitory connections</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синхронизация</kwd><kwd>интериктальные разряды</kwd><kwd>ГАМК-Б-рецепторы</kwd><kwd>обратные тормозные связи</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Марченко В.Г., Зайченко М.И.
