Известно, что фокальная активность (ФА), регистрируемая в обонятельной луковице (ОЛ), в значительной степени генерируется в ее локальных нейронных сетях, имеет непосредственное отношение к обработке ольфакторной информации и подвержена влиянию различных факторов, в том числе анестетиков. С использованием 8-электродных матриц на шести взрослых самцах серых доминитицированных крыс в хронических экспериментах исследовали эффекты ксилазин-тилетамин-золазепамовой (КТЗ) анестезии на спектральные характеристики и когерентность ФА, регистрируемой с дорзальной поверхности ОЛ в частотном диапазоне 1–150 Гц в течение двух часов. Показано, что наиболее существенные изменения в ФА ОЛ крыс в КТЗ- наркозе наблюдаются в области высоких гамма-частот. Статистически значимое увеличение мощности (в 2–4 раза) и когерентности (до 50%) этих частот наблюдалось в ФА всех животных уже в течение 10–15 мин от начала наркотизации. При этом, если в бодрствовании модальные значения этих частот приходились на область 70–80 Гц, то по прошествии указанного времени – 110–130 Гц. В динамике наркоза наблюдалось постепенное смещение модального значения в распределении их мощности влево, в область более низких частот (90–110 Гц), при этом их суммарная мощность (но не когерентность) статистически значимо снижалась лишь на фоне выхода животного из наркоза.

Ключевые слова: обонятельная луковица, фокальная активность, гамма-активность, когерентность, ксилазин-тилетамин-золазепамовый наркоз
